Chan TG, Plageman J, Yu JL. The Repeatability of Pharyngeal Opening Pressure Under Drug-Induced Sleep Endoscopy. Otolaryngol Head Neck Surg 2024; 171:295-302. [PMID: 38606621 PMCID: PMC11211064 DOI: 10.1002/ohn.730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 02/01/2024] [Accepted: 02/09/2024] [Indexed: 04/13/2024]
Abstract
OBJECTIVE Pharyngeal opening pressure (PhOP) is a measure of upper airway collapsibility that can be obtained during drug-induced sleep endoscopy (DISE) using a continuous positive airway pressure (CPAP) titration. However, the stability of PhOP over the course of sedation during DISE remains unclear. This study aims to compare repeat measures of PhOP over the course of DISE. STUDY DESIGN Single arm prospective study. SETTING Single tertiary care institution. METHODS Patients had 2 CPAP titrations while undergoing DISE. Collected data included patient demographics, PhOP, patient sedation index (PSI), and duration of and between CPAP titrations. t Tests, test-retest coefficient analysis, and repeated measures correlation were performed. RESULTS Twenty-five patients completed the study between 2022 and 2023 with 22 patients having sedation depth (PSI) recording. Most were male (76%), obese (average body mass index: 30.24 kg/m2), with severe obstructive sleep apnea (average apnea-hypopnea index: 39.8 events/hr). Test-retest analysis showed good-excellent correlation between PhOP values (intraclass correlation coefficient = 0.892, P < .0001, n = 25). Average time between CPAP titrations was 15 minutes to 6 seconds. Over that time, PhOP increased by an average of 0.72 cmH2O (P = .06, n = 25) and PSI decreased by 9.5 units (P = .01, n = 22). Repeated measures correlation showed a weak negative correlation between PhOP and PSI (r = -.45, P = .03, n = 22). CONCLUSION The results showed repeatability of PhOP values over the course of DISE. When adjusted for sedation depth (PSI), deeper sedation was weakly associated with greater PHOP. However, the magnitude of this change was small and we conclude that PhOP remains relatively stable over the course of DISE (Effects of Lung Volume on Upper Airway Patency During DISE [DISE-Pulm], NCT05350332, clinicaltrials.gov).

Residual upper airway obstruction during nocturnal noninvasive ventilation despite high positive expiratory pressure. Impact of oronasal mask to nasal mask switch. Respir Med Res 2024; 85:101083. [PMID: 38232657 DOI: 10.1016/j.resmer.2023.101083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 12/08/2023] [Accepted: 12/15/2023] [Indexed: 01/19/2024]
Abstract
BACKGROUND Nasal mask (NM) and oronasal masks (OM) can be used to provide noninvasive ventilation (NIV). Recent studies suggested that OM is the most used interface and that there is no difference in efficacy or in tolerance between OM and NM for chronic use. However, studies focusing on video laryngoscopy underlined the impact of OM in residual upper airway obstruction (UAO) under NIV. We sought to assess the real-life practice of switching from OM to NM when UAO events persist despite high EPAP levels. METHODS In an open-label single center prospective cohort study, data from files and full night polysomnography on NM and OM were collected for patients wearing OM and presenting an UAO index ≥15/h despite an EPAP level ≥ 10 cmH20. RESULTS Forty-four patients were included in the study. In 31 patients (74 %), switching to a NM reduced UAOi to ≥10/h. Interestingly, 92 % of these patients still had NM at 3 to 12 months of follow-up. Switching to a NM was also associated with a trend in paCO2 reduction and significant improvements in Epworth, sleep quality and NIV compliance. Successful interface switching was significantly associated with female gender, and a trend was observed in non-smokers. CONCLUSION As for CPAP, switching to a NM improved NIV efficacy in a selected group of patients presenting residual UAO events despite high EPAP levels. Additionally, this switch has an impact on compliance and subjective sleepiness. Thus, in patients with persisting UAO on OM, switching to a NM could be a first-line intervention before considering further investigation such as polygraphy or video laryngoscopy. We also derive an algorithm for mask allocation and adaptation in acute and chronic NIV use.

Sleep Breath 2023; 27:1787-1794. [PMID: 36753005 DOI: 10.1007/s11325-023-02787-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 01/27/2023] [Accepted: 01/30/2023] [Indexed: 02/09/2023]
Abstract
BACKGROUND Continuous positive airway pressure (CPAP) therapy is recommended for moderate-to-severe obstructive sleep apnea (OSA). We aimed to investigate whether or not combining drug-induced sleep endoscopy (DISE) with CPAP titration may inform more appropriate pressure settings. MATERIALS AND METHODS A sleep CPAP titration study and DISE-CPAP treatment were performed on consecutive subjects with moderate-to-severe OSA under controlled sedation using bispectral monitoring. Video recordings of dynamic changes in UA with CPAP pressure ranges of 5 to 25 cm were assessed in accordance with the VOTE classification. The 95th percentile (95th PC) pressure of the CPAP titration trial was compared to optimal pressure for alleviating UA blockage. RESULTS We included 30 subjects (mean age 37.5, 17% women). All showed UA collapse at more than one level, with more than 80% of them collapsing completely at the levels of the velum and oropharynx. At the velum, 90% of subjects experienced improvement with CPAP. At the oropharynx, 75% of subjects experienced improvement with CPAP. The mean pressure and standard deviation (SD) of the 95th PC of the CPAP titration was 14.3 (3.5) cmH2O, while the pressure required to partially or fully open the airway (best possible pressure) was 16.1 (3.9) cmH2O; mean (SD) difference, 1.9 (2.2); P ≤ 0.001. The limits of agreement between the CPAP 95th pressure and the ideal pressure were - 6.32 to + 2.52. CONCLUSIONS The palate and lateral pharynx were more affected by CPAP than the hypopharynx. Most of the time, the mean 95th PC CPAP titration pressure was lower than the mean optimal pressure needed to alleviate the collapse.

Oronasal vs Nasal Masks: The Impact of Mask Type on CPAP Requirement, Pharyngeal Critical Closing Pressure (P crit), and Upper Airway Cross-Sectional Areas in Patients With OSA. Chest 2023; 164:747-756. [PMID: 36990149 DOI: 10.1016/j.chest.2023.03.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 03/08/2023] [Accepted: 03/15/2023] [Indexed: 03/28/2023] Open
Abstract
BACKGROUND CPAP delivered via an oronasal mask is associated with lower adherence, higher residual apnea-hypopnea index (AHI), and increased CPAP therapeutic pressure compared with nasal masks. However, the mechanisms underlying the increased pressure requirements are not well understood. RESEARCH QUESTION How do oronasal masks affect upper airway anatomy and collapsibility? STUDY DESIGN AND METHODS Fourteen patients with OSA underwent a sleep study with both a nasal and oronasal mask, each for one-half of the night (order randomized). CPAP was manually titrated to determine therapeutic pressure. Upper airway collapsibility was assessed using the pharyngeal critical closing pressure (Pcrit) technique. Cine MRI was done to dynamically assess the cross-sectional area of the retroglossal and retropalatal airway throughout the respiratory cycle with each mask interface. Scans were repeated at 4 cm H2O and at the nasal and oronasal therapeutic pressures. RESULTS The oronasal mask was associated with higher therapeutic pressure requirements (ΔM ± SEM; +2.6 ± 0.5; P < .001) and higher Pcrit (+2.4 ± 0.5 cm H2O; P = .001) compared with the nasal mask. The change in therapeutic pressure between masks was strongly correlated with the change in Pcrit (r2 = 0.73; P = .003). Increasing CPAP increased both the retroglossal and retropalatal airway dimensions across both masks. After controlling for pressure and breath phase, the retropalatal cross-sectional area was moderately larger when using a nasal vs an oronasal mask (+17.2 mm2; 95% CI, 6.2-28.2, P < .001) while nasal breathing. INTERPRETATION Oronasal masks are associated with a more collapsible airway than nasal masks, which likely contributes to the need for a higher therapeutic pressure.

[PMID: 36214944 DOI: 10.1007/s11325-022-02721-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 09/23/2022] [Accepted: 09/30/2022] [Indexed: 11/05/2022]
Abstract
PURPOSE The purpose of this study was to compare the effectiveness of nasal pillows with standard nasal masks in the treatment of patients with obstructive sleep apnea (OSA). METHODS A digitalized search was carried out in four different databases including PubMed, Scopus, EMBASE, and CENTRAL using relevant keywords along with a manual search in relevant journals. All comparative studies comparing outcomes of using a nasal pillow with the use of standard nasal masks for continuous positive airway pressure (CPAP) treatment in patients with OSA were included. The qualitative analysis was carried out by tabulating the demographic data. The quantitative data were subjected to meta-analysis. The quality of comparative studies (both retrospective and prospective cohorts) was evaluated using New-castle Ottawa scale (NOS). RESULTS A total of 14 studies (eight prospective and six retrospective) were included in the review. Of them, five studies were randomized and were of cross-over study design. No significant differences were observed in achieved CPAP and residual apnea-hypopnea index (AHI) levels between the nasal pillow and nasal mask with SMD - 0.05 95% CI [- 0.18, 0.09], p = 0.50 and SMD - 0.13 95% CI [- 0.28, 0.03], p = 0.12, respectively. However, nasal pillow usage was associated with better CPAP adherence with a difference of only + 0.29 min/night as compared to a standard nasal mask, with SMD 0.29 95% CI [0.07, 0.50], p = 0.009. CONCLUSION Nasal pillow and standard nasal mask were equally effective in terms of residual AHI level and achieved similar therapeutic CPAP pressures. However, the difference in CPAP adherence between groups, though statistically significant, is of questionable clinical significance.

Abstract
BACKGROUND Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). METHODS Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. RESULTS The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. CONCLUSION This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.

Fashanu OS, Quan SF. Factors associated with treatment outcomes after use of auto-titrating CPAP therapy in adults with obstructive sleep apnea. Sleep Breath 2023; 27:165-172. [PMID: 35284979 DOI: 10.1007/s11325-022-02590-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 02/18/2022] [Accepted: 03/02/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To determine factors that are associated with OSA therapy outcomes with auto-titrating positive airway pressure (APAP). METHODS We sequentially grouped patients from a retrospective cohort based on APAP efficacy (sufficiently vs. insufficiently treated; insufficiently treatment defined as residual AHI of ≥ 5), therapy adherence (adherent vs. non-adherent, non-adherence defined as < 70% usage for ≥ 4 h/night), and therapy outcomes (optimal vs. non-optimal and non-optimal outcomes defined as non-adherent and/or insufficiently treated). We subsequently compared each group. RESULTS The insufficiently treated were older (68.4 ± 12.5 vs. 60.4 ± 13.1 years, p < 0.01) and had lower BMI (31.9 ± 6.3 vs. 37.9 ± 9.1 kg/m2, p < 0.01). They had higher baseline central apnea indices (CAI), longer leaks, higher peak pressures, and were less compliant. The non-adherent were younger (61.1 ± 12.6 vs. 65.5 ± 13.2 years, p = 0.03) and comprised more females (56.1 vs. 43.9%, p = 0.04). The leak duration per usage hour was higher in the non-compliant (median: 1.5; IQR 7.9 vs. median: 0.3; IQR 1.9 min/h; p < 0.01). The non-optimally treated had lower BMI, longer leaks, and less nightly usage. Multivariate analyses showed that leak duration was the common factor associated with treatment effectiveness and optimal therapy outcomes. CONCLUSIONS Various demographic and clinical factors were associated with treatment efficacy and adherence. However, leak duration was the common factor related to treatment efficacy and overall optimal therapy outcomes.

Abstract
Until now, no study has directly network meta-analysed the impact of nasal masks, nasal pillows and oronasal masks on continuous positive airway pressure therapy in patients with obstructive sleep apnea. This study aimed to meta-analyse the impact of three kinds of nasal interfaces with both network meta-analysis and pairwise comparison. PubMed, EMBASE, CENTRAL and ClinicalTrials.gov were systematically searched from inception to December 2020 for studies that compared the three types of nasal interfaces for treating obstructive sleep apnea with continuous positive airway pressure. The outcomes were residual apnea-hypopnea index, continuous positive airway pressure, and nightly average usage. The network meta-analysis was conducted using multivariate random-effects in a frequentist framework where three interfaces were ranked with the surface under the cumulative ranking probabilities. The pairwise comparison was conducted using random-effects meta-analysis. Twenty-nine articles comprising 6378 participants were included. The pairwise comparison showed both nasal masks and nasal pillows were associated with lower residual apnea-hypopnea index, lower continuous positive airway pressure, and higher continuous positive airway pressure adherence compared with oronasal masks. The surface under the cumulative ranking confirmed that nasal masks were associated with the lowest residual apnea-hypopnea index and highest adherence, while pillows were associated with the lowest continuous positive airway pressure. The meta-regression identified that lower pretreatment apnea-hypopnea index and continuous positive airway pressure determined during continuous positive airway pressure titration (versus determined during continuous positive airway pressure therapy) was associated with lower continuous positive airway pressure with nasal masks and nasal pillows. In conclusion, compared with oronasal masks, nasal masks and nasal pillows are better interfaces, especially in patients with lower pretreatment apnea-hypopnea index and those with the therapeutic pressure determined during continuous positive airway pressure titration.

Abstract
OBJECTIVE Continuous Positive Airway Pressure (CPAP) is the gold standard treatment for OSA. A wide variety of masks are used during CPAP therapy. The aim of the study is to compare polysomnography outcomes during titration for different types of masks (oronasal, nasal and pillow) and assess the impact on PAP titration. METHODS We retrospectively analyzed all CPAP titration polysomnography for one year. Anthropometric data and baseline apnea severity were documented. RESULTS A total of 497 patients were evaluated. Nasal masks were used in 82.3% (n = 409), pillow in 14.1% (n = 70) and oronasal in 3.6% (n = 18). There was no difference according to body mass index and baseline apnea-hypopnea index among the groups. The oronasal group was older and had higher titrated CPAP pressure, higher residual apnea-hypopnea index, lower sleep efficiency, more superficial N1 sleep and longer wake time after sleep onset. All other polysomnography outcomes were similar among the groups. The mean CPAP level was 11.6 ± 2.1 cm H2O for the oronasal mask, 10.1 ± 2.1 cm H2O for the nasal mask and 9.8 ± 2.2 cm H2O for the pillow. The residual apnea-hypopnea index was 10.4 ± 7.9 for the oronasal mask, 5.49 ± 5.34 events/h for the nasal mask and 4.98 ± 5.48 events/h for the pillow. The baseline apnea-hypopnea index was correlated with of a higher CPAP pressure for all the groups (p < 0.001 for the nasal group, p = 0.001 for the pillow group and p = 0.049 for the oronasal group). Body mass index and residual AHI were correlated with of a higher CPAP pressure for the nasal and pillow groups only (p < 0.001). CONCLUSION The interface can have a significant impact on the effectiveness of PAP titration. Patients with oronasal masks have higher CPAP pressure, higher residual apnea-hypopnea index, lower sleep efficiency and higher wake time after sleep onset. Oronasal masks should not be recommended as the first choice for apnea patients. LEVEL OF EVIDENCE Level 3.

Abstract
Continuous positive airway pressure (CPAP) remains the major treatment option for obstructive sleep apnea (OSA). The American Thoracic Society organized a workshop to discuss the importance of mask selection for OSA treatment with CPAP. In this workshop report, we summarize available evidence about the breathing route during nasal and oronasal CPAP and the importance of nasal symptoms for CPAP outcomes. We explore the mechanisms of air leaks during CPAP treatment and possible alternatives for leak control. The impact of nasal and oronasal CPAP on adherence, residual apnea-hypopnea index, unintentional leaks, and pressure requirements are also compared. Finally, recommendations for patient and partner involvement in mask selection are presented, and future directions to promote personalized mask selection are discussed.

Abstract
BACKGROUND The optimal interface for the delivery of home non-invasive ventilation (NIV) to treat chronic respiratory failure has not yet been determined. The aim of this individual participant data (IPD) meta-analysis was to compare the effect of nasal and oronasal masks on treatment efficacy and adherence in patients with COPD and obesity hypoventilation syndrome (OHS). METHODS We searched Medline and Cochrane Central Register of Controlled Trials for prospective randomised controlled trials (RCTs) of at least 1 month's duration, published between January 1994 and April 2019, that assessed NIV efficacy in patients with OHS and COPD. The main outcomes were diurnal PaCO2, PaO2 and NIV adherence (PROSPERO CRD42019132398). FINDINGS Of 1576 articles identified, 34 RCTs met the inclusion criteria and IPD were obtained for 18. Ten RCTs were excluded because only one type of mask was used, or mask data were missing. Data from 8 RCTs, including 290 IPD, underwent meta-analysis. Oronasal masks were used in 86% of cases. There were no differences between oronasal and nasal masks for PaCO2 (0.61 mm Hg (95% CI -2.15 to 3.38); p=0.68), PaO2 (-0.00 mm Hg (95% CI -4.59 to 4.58); p=1) or NIV adherence (0·29 hour/day (95% CI -0.74 to 1.32); p=0.58). There was no interaction between the underlying pathology and the effect of mask type on any outcome. INTERPRETATION Oronasal masks are the most used interface for the delivery of home NIV in patients with OHS and COPD; however, there is no difference in the efficacy or tolerance of oronasal or nasal masks.

Efficacy of nasal masks versus nasal pillows masks during continuous positive airway pressure titration for patients with obstructive sleep apnea. Sleep Breath 2021; 25:1-8. [PMID: 33403598 DOI: 10.1007/s11325-020-02251-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 11/02/2020] [Accepted: 11/12/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE Nasal masks are usually the first choice for CPAP therapy, but patients may experience side effects. There are limited data regarding the efficacy of nasal pillows masks during CPAP titration. This study aimed to compare the polysomnography outcomes during CPAP titration while comparing two types of masks (nasal and pillows) and to assess whether or not the patient characteristics differed between mask preferences. METHODS In a sleep-disorders clinic, we prospectively analyzed all patients undergoing CPAP titration for three consecutive months. CPAP pressures were manually titrated. Anthropometric data (age, sex, body mass index, and neck and waist circumferences) and OSA severity were documented. Patients completed a self-administered questionnaire that measured nasal obstruction (NOSE scale). Before titration, both types of masks were presented to patients, and each of them chose the one they preferred. RESULTS Of 157 patients, 55% (n = 86) used nasal masks, and 45% (n = 71) used nasal pillows masks. There was no difference according to mask type chosen by age, sex, body mass index, neck and waist circumferences, and NOSE scale. Polysomnography outcomes were similar between the mask groups. The mean CPAP level was 9.4 ± 1.8 cm H2O for nasal masks and 9.1 ± 2.0 cm H2O for nasal pillows (p = 0.61). Residual apnea-hypopnea index was 3.0 ± 2.8 events/h for nasal mask and 3.5 ± 4.1 events/h for pillow mask (p = 0.28). Baseline AHI, body mass index, neck and waist circumferences, and residual AHI were independent predictors of a higher CPAP pressure for both groups (p < 0.0001). CONCLUSIONS Nasal pillows masks seem to be as effective as nasal masks and may be considered to be an initial choice for CPAP titration.

Abstract
Patient interface preference is a key factor in positive airway pressure compliance. Local side effects are common. Proper mask fitting and patient education are important. Masks should seal well and fit comfortably. Nasal, nasal pillow, and oronasal masks can be effective interfaces. Most patients with obstructive sleep apnea prefer a nasal mask. Oronasal masks can be a useful alternative. Nasal pillows can reduce mask size and improve comfort. Oronasal masks may require a higher pressure. A significantly lower pressure may be effective with a nasal interface. Proper mask fitting requires testing the mask seal under the treatment pressure.

Abstract
PURPOSE Mask type (nasal versus oronasal) can affect the optimal pressure required to correct the apnea/hypopnea index (AHI) in obstructive sleep apnea (OSA) subjects treated with CPAP. Our objective was to evaluate if mask type influenced CPAP titration outcomes in OSA patients. METHODS A retrospective study of individuals with a baseline AHI ≥ 15.0/h, who received an auto-adjusting CPAP titrating device (S9 AutoSet ResMed®) in a sleep-lab setting. The mask type oronasal (OM) or nasal (NM) was always selected by the patients. Optimal pressure requirements, leak, and residual AHI were compared based on mask type. RESULTS Overall, 436 patients were included: 283 with NM (64.9%) and 153 with OM (35.1%). At baseline, NM and OM cohorts had similar AHI (p = 0.160). Patients allocated to the OM cohort had a higher 95th percentile pressure, a higher 95th percentile leak, and a higher residual AHI than those with a NM: pressure requirement: 12.9 cm H2O (IQR: 10.6-15.0) versus 10.7 cm H2O (IQR: 9.2-12.3); leak: 21.6 L/min (IQR: 9.6-37.2) versus 9.6 L/min (IQR: 3.6-19.2); and residual AHI: 4.9/h (IQR: 2.4-10.2) versus 2.2/h (IQR: 1.0-4.4), respectively (p < 0.001 for all). CONCLUSIONS CPAP mask type based on individual preferences exerts profound effects on optimal CPAP pressures and efficacy. Patients titrated with OM showed higher pressure requirements, had higher a leak, and higher residual AHI when compared to NM, which may adversely impact treatment adherence and other health outcomes.

Abstract
Oronasal breathing may adversely impact obstructive sleep apnea (OSA) patients either by increasing upper airway collapsibility or by influencing continuous positive airway pressure (CPAP) treatment outcomes. Predicting a preferential breathing route would be helpful to guide CPAP interface prescription. We hypothesized that anthropometric measurements but not self-reported oronasal breathing are predictors of objectively measured oronasal breathing. Seventeen OSA patients and nine healthy subjects underwent overnight polysomnography with an oronasal mask with two sealed compartments attached to independent pneumotacographs. Subjects answered questionnaires about nasal symptoms and perceived breathing route. Oronasal breathing was more common (P = <0.001) among OSA patients than controls while awake (62 ± 44 vs. 5 ± 6%) and during sleep (59 ± 39 vs. 25 ± 21%, respectively). Oronasal breathing was associated with OSA severity (P = 0.009), age (P = 0.005), body mass index (P = 0.044), and neck circumference (P = 0.004). There was no agreement between objective measurement and self-reported breathing route among OSA patients while awake (κ = -0.12) and asleep (κ = -0.02). The breathing route remained unchanged after 92% of obstructive apneas. These results suggest that oronasal breathing is more common among OSA patients than controls during both wakefulness and sleep and is associated with OSA severity and anthropometric measures. Self-reporting is not a reliable predictor of oronasal breathing and should not be considered an indication for oronasal CPAP.NEW & NOTEWORTHY Continuous positive airway pressure (CPAP) interface choice for obstructive sleep apnea (OSA) patients is often guided by nasal symptoms and self-reported breathing route. We showed that oronasal breathing can be predicted by anthropometric measurements and OSA severity but not by self-reported oronasal breathing. Self-reported breathing and nasal symptoms should not be considered for CPAP interface choice.

Comparison of Auto- and Fixed-Continuous Positive Airway Pressure on Air Leak in Patients with Obstructive Sleep Apnea: Data from a Randomized Controlled Trial. Can Respir J 2019; 2019:6310956.

Abstract
Auto-CPAP may cause sleep fragmentation due to variations in pressure and unintentional leaks. The aim of this study was to compare air leak between fixed-CPAP and auto-CPAP after 4 months of CPAP treatment. This study is an ancillary analysis of a randomized, double-blind, parallel, controlled trial over 4 months, comparing fixed- and auto-CPAP in newly diagnosed patients with OSA. The following data were extracted from the CPAP devices: mean and 90th percentile pressure, residual apnea-hypopnea index, mean CPAP use, and amount of leak. Within each arm, patients were also randomly allocated to use of one of the three different brands of devices. Since the leak was reported differently for each device, median leak value was determined for each brand and leaks were classified as “above the median” or “below the median”. Data from 269 patients were analyzed. The univariate analysis showed that tobacco consumption, CPAP level, and oronasal masks were associated with leaks above the median value but not the type of CPAP. The multivariate analysis showed that only CPAP level and oronasal masks were associated with leaks below the median. There were no differences in the types of mask used between fixed- and auto-CPAP. There was no impact of the type of CPAP on leaks or the type of interface used. We used a method based on the median leak value to standardize comparisons across devices which report leaks with different definitions.

Abstract
BACKGROUND An oronasal mask is frequently used to treat OSA. In contrast to nasal CPAP, the effectiveness of oronasal CPAP varies by unknown mechanisms. We hypothesized that oral breathing and pressure transmission through the mouth compromises oronasal CPAP efficacy. METHODS Thirteen patients with OSA, well adapted to oronasal CPAP, were monitored by full polysomnography, pharyngeal pressure catheter, and nasoendoscope. Patients slept with low doses of midazolam, using an oronasal mask with sealed nasal and oral compartments. CPAP was titrated during administration by the oronasal and nasal routes, and was then reduced to induce stable flow limitation and abruptly switched to the alternate route. In addition, tape sealing the mouth was used to block pressure transmission to the oral cavity. RESULTS Best titrated CPAP was significantly higher by the oronasal route rather than the nasal route (P = .005), and patients with > 25% oral breathing (n = 5) failed to achieve stable breathing during oronasal CPAP. During stable flow limitation, inspiratory peak flow was lower, driving pressure was higher, upper airway inspiratory resistance was higher, and retropalatal and retroglossal area were smaller by the oronasal rather than nasal route (P < .05 for all comparisons). Differences were observed even among patients with no oral flow and were abolished when tape sealing the mouth was used (n = 6). CONCLUSIONS Oral breathing and transmission of positive pressure through the mouth compromise oronasal CPAP.

Abstract
OBJECTIVES To compare interfaces performance during home-based automatic titration (APAP). METHODS Retrospective study based on APAP titration from Obstructive Sleep Apnea Syndrome (OSA) patients. RESULTS 707 patients, 513 men (70.6%), were titrated. Masks were 104 pillows (14.7%), group I (GI); 532 nasal (75.2%), group II (GII); and 71 oronasal masks (10%), group III (GIII). We found differences in effective pressure to the device (P90/P95) (GI: 7.13±1.9 vs. GII: 8.3±2.1 vs. GIII: 9.3±2.6 cmH2O, p <0.001) but not in final pressure titrated manually (GI: 7.9±1.4 vs. GII: 8.6±1.6 vs. GIII: 9.2±1.9 cm of H2O, p >0.5), where lower residual AHI for pillows was p <0.001 and leaks for nasal were p <0.001. No differences were found in compliance (hours) (GI: 6.3±1.2 vs. GII: 6.2±1.1 vs. GIII: 6.1±1.0, p <0.4). CONCLUSION During auto-adjusting titration by CPAP-naïve patients, nasal masks had lower leak rates and nasal pillows presented a similar performance.

Abstract
INTRODUCTION The purpose of this systematic review is to provide supporting evidence for the clinical practice guideline for the treatment of obstructive sleep apnea (OSA) in adults using positive airway pressure (PAP). METHODS The American Academy of Sleep Medicine commissioned a task force of experts in sleep medicine. A systematic review was conducted to identify studies that compared the use of PAP with no treatment as well as studies that compared different PAP modalities. Meta-analyses were performed to determine the clinical significance of using PAP in several modalities (ie, continuous PAP, auto-adjusting PAP, and bilevel PAP), to treat OSA in adults. In addition, meta-analyses were performed to determine the clinical significance of using an in-laboratory versus ambulatory strategy for the initiation of PAP, educational and behavioral interventions, telemonitoring, humidification, different mask interfaces, and flexible or modified pressure profile PAP in conjunction with PAP to treat OSA in adults. Finally, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process was used to assess the evidence for making recommendations. RESULTS The literature search resulted in 336 studies that met inclusion criteria; 184 studies provided data suitable for meta-analyses. The data demonstrated that PAP compared to no treatment results in a clinically significant reduction in disease severity, sleepiness, blood pressure, and motor vehicle accidents, and improvement in sleep-related quality of life in adults with OSA. In addition, the initiation of PAP in the home demonstrated equivalent effects on patient outcomes when compared to an in-laboratory titration approach. The data also demonstrated that the use of auto-adjusting or bilevel PAP did not result in clinically significant differences in patient outcomes compared with standard continuous PAP. Furthermore, data demonstrated a clinically significant improvement in PAP adherence with the use of educational, behavioral, troubleshooting, and telemonitoring interventions. Systematic reviews for specific PAP delivery method were also performed and suggested that nasal interfaces compared to oronasal interfaces have improved adherence and slightly greater reductions in OSA severity, heated humidification compared to no humidification reduces some continuous PAP-related side effects, and pressure profile PAP did not result in clinically significant differences in patient outcomes compared with standard continuous PAP.

Abstract
Obstructive sleep apnea (OSA) is a common disease which impacts quality of life, mood, cardiovascular morbidity, and mortality. Continuous positive airway pressure (CPAP) is the first-line treatment for patients with moderate to severe OSA. CPAP ameliorates respiratory disturbances, leading to improvements in daytime sleepiness, quality of life, blood pressure, and cognition. However, despite the high efficacy of this device, CPAP adherence is often sub-optimal. Factors including: socio-demographic/economic characteristics, disease severity, psychological factors, and side-effects are thought to affect CPAP adherence in OSA patients. Intervention studies have suggested that augmented support/education, behavioral therapy, telemedicine and technological interventions may improve CPAP adherence. In this paper, we will extensively review the most common factors including age, gender, race/ethnicity, socioeconomic status, smoking status, severity of OSA, severity of OSA symptoms, psychological variables, social support, marital status/bed partner involvement, dry nose and mouth, mask leak, and nasal congestion that may predict CPAP adherence. We will also extensively review interventions that may increase adherence to CPAP.

Abstract
INTRODUCTION Continuous positive airway pressure (CPAP) therapy is a clinical treatment for moderate or severe obstructive sleep apnea (OSA). Commercial CPAP mask designs normally come in standard sizes and the configuration is not commonly tailored to the patients' characteristics such as face topology, skin sensitivity, and severity of OSA syndrome; however, an optimal mask/interface selection is a key factor influencing the compliance and effectiveness of CPAP treatment. AREAS COVERED This review investigates the conventional CPAP mask design, its effect on OSA treatment, and the related risk factors that can lead to skin damage after long-term repeated use. Through a literature search on common databases, Scopus, PubMed, and Google Scholar, we identified reported facts on the influence of the mask interface and current trends toward customized devices. EXPERT COMMENTARY There is potential for optimizing the CPAP mask fit by adapting the interface to the patients' individual characteristics. This holds particularly true for users with abnormal features or simply outside conventional industry sizing standards. Enabling technologies for undertaking this adaptation include reverse engineering, computational modeling, and additive manufacturing. There is to date no integrated system that integrates those elements into a standard solution, but several studies have shown its effectiveness for specific cohorts.

Abstract
BACKGROUND AND OBJECTIVE A major challenge with the treatment of obstructive sleep apnoea (OSA) is adherence to continuous positive airway pressure (CPAP) therapy. Mask tolerability is an important determinant of adherence, however evidence to guide selection of mask interfaces is lacking. METHODS We conducted a randomized crossover trial of mask interfaces in CPAP therapy for moderate-to-severe OSA to assess adherence and efficacy of CPAP therapy with nasal mask, nasal pillow and oronasal masks. Demographic data, Nasal Obstruction Symptom Evaluation (NOSE) scores and craniofacial measurements were also analysed for associations with adherence with oronasal masks. RESULTS Eighty-five patients were included in the study (mean ± SD age: 46 ± 12 years; body mass index: 29.9 ± 5.6 kg/m2 ; apnoea-hypopnoea index (AHI): 53.6 ± 24.0 events/h). Patients had better adherence with nasal masks (average night use: 3.96 ± 2.26 h/night) compared to oronasal masks (3.26 ± 2.18 h/night, P < 0.001) and nasal pillows (3.48 ± 2.20 h/night, P = 0.007). Residual AHI was higher with oronasal masks (7.2 ± 5.2) compared to nasal masks (4.0 ± 4.2, P < 0.001) and nasal pillows (4.1 ± 3.3, P < 0.001). Twenty-two (25.9%) patients had the best adherence with oronasal masks (4.22 ± 2.14 vs 2.93 ± 2.12 h/night, P = 0.016). These patients had lower NOSE scores (15 (0-35) vs 40 (10-55), P = 0.024) and larger menton-labrale inferioris/biocular width ratios (31 ± 3% vs 28 ± 4%, P = 0.019). CONCLUSION Nasal masks are the preferred interface during CPAP initiation. Patients with less nasal obstruction and a proportionally increased chin-lower lip distance to mid-face width may have better CPAP adherence with an oronasal mask interface.

Abstract
PURPOSE OF REVIEW Continuous positive airway pressure (CPAP) delivered by nasal mask is the gold standard treatment for obstructive sleep apnea (OSA). However, oral and oronasal masks are also available. We considered experimental evidence and reviewed clinical trials that evaluated the impact of oral and oronasal mask on OSA treatment. RECENT FINDINGS One recent study in 18 OSA patients that slept with a customized oronasal mask with two sealed compartments showed that the change of CPAP flow from nasal to oronasal and oral caused upper airway obstruction because of posterior displacement of the tongue demonstrated by nasoendoscopy. Oral masks use a mouthpiece that may stabilize the jaw and the tongue and have shown to be effective. However, oral masks are not widely used in clinical practice. Four out of five observational studies and all five reviewed randomized studies showed a worse performance of oronasal when compared with nasal masks. Oronasal masks were associated with higher residual apnea-hypopnea index, lower adherence, more leaks, and less satisfaction than nasal mask in the majority of the studies. SUMMARY Nasal CPAP must be the first choice to treat OSA. Patients on oronasal mask should be carefully followed. VIDEO ABSTRACT.

Abstract
STUDY OBJECTIVES To determine if the type of continuous positive airway pressure (CPAP) mask interface influences CPAP treatment efficacy, adherence, side effects, comfort and sleep quality in patients with moderate-severe obstructive sleep apnea (OSA). METHODS This took place in a hospital-based tertiary sleep disorders unit. It is a prospective, randomized, crossover trial comparing three CPAP interfaces: nasal mask (NM), nasal mask plus chinstrap (NM-CS) and oronasal mask (ONM) each tried in random order, for 4 weeks. After each 4-week period, patient outcomes were assessed. Participants had a new diagnosis of obstructive sleep apneas. Forty-eight patients with moderate-severe OSA (32 males, mean ± standard deviation apnea-hypopnea index (AHI) 55.6 ± 21.1 events/h, age 54.9 ± 13.1 years, body mass index 35.8 ± 7.2 kg/m2) were randomized. Thirty-five participants completed the full study, with complete data available for 34 patients. RESULTS There was no statistically significant difference in CPAP adherence; however, residual AHI was higher with ONM than NM and NM-CS (residual AHI 7.1 ± 7.7, 4.0 ± 3.1, 4.2 ± 3.7 events/h respectively, main effect P = .001). Patient satisfaction and quality of sleep were higher with the NM and NM-CS than the ONM. Fewer leak and mask fit problems were reported with NM (all chi-square P < .05), which patients preferred over the NM-CS and ONM options (n = 22, 9 and 4 respectively, P = .001). CONCLUSIONS The CPAP adherence did not differ between the three different mask interfaces but the residual AHI was lower with NM than ONM and patients reported greater mask comfort, better sleep, and overall preference for a NM. A nasal mask with or without chinstrap should be the first choice for patients with OSA referred for CPAP treatment.

Abstract
OBJECTIVES The primary objective of the study was to understand the differential impact of continuous positive airway pressure (CPAP) on the location, degree and pattern of airway collapse in obstructive sleep apnea (OSA) patients utilizing drug-induced sleep endoscopy (DISE). STUDY DESIGN Non-randomized trial. SETTING University Medical Center. PARTICIPANTS Fifteen consecutive OSA patients undergoing DISE. MAIN OUTCOMES AND MEASURES The patterns of airway collapse were videorecorded at baseline and under differential application of nasal CPAP (nCPAP) at 5, 10 and 15 cm H2 O. For each modality, the pattern and degree of airway collapse were analyzed by three independent observers using the velum, oropharynx, tongue base, epiglottis (VOTE) classification system. RESULTS The modest nCPAP pressures (10 cm H2 O) had the greatest impact on the lateral walls of the pharynx, followed by the palatal region. The collapsibility of the tongue base and epiglottis demonstrated significant resistance to nCPAP application, which was overcome by increasing nCPAP to 15 cm H2 O. Compared to 5 cm H2 O, nCPAP pressures of 10 and 15 cm H2 O improved complete collapse at least at one level of the upper airway (P=.016 and .001, respectively). Increased nCPAP pressures also led to changes in the configuration of airway collapse at the level of the velum. CONCLUSIONS The differential nCPAP effects observed in this study may help to understand some of the mechanisms responsible for inadequate patient response and poor nCPAP compliance. The use of DISE in combination with CPAP may serve as a first step in optimizing patients that failed to adapt to treatment with CPAP. This approach can help the physician identify patterns of airway collapse that may require varying pressures different from the one the patient is using, as well as anatomical factors that may be corrected to help with compliance.

Abstract
CPAP is the first-line treatment for moderate to severe OSA syndrome. Up to 25% of patients with OSA syndrome discontinue CPAP treatment due to side effects. Unintentional leakage and its associated annoying consequences are the most frequently reported adverse effects of CPAP. Successive technological improvements have not succeeded in addressing this issue. A systematic review was conducted (1) to assess the impact of different technological advances on unintentional leaks and (2) to determine if any patient characteristics have already been identified as determinants of unintentional leakage. No CPAP modality was superior to another in reducing unintentional leaks and, surprisingly, oronasal masks were associated with higher unintentional leaks. Nasal obstruction, older age, higher BMI, central fat distribution, and male sex might be associated with an increased risk of unintentional leakage. Such leaks remain an important problem. Further studies are needed to improve the understanding of underlying clinical factors so that patients at risk of unintentional leaks may be identified and individualized solutions applied.

Ebben MR, Narizhnaya M, Krieger AC. A new predictive model for continuous positive airway pressure in the treatment of obstructive sleep apnea. Sleep Breath 2016; 21:435-442. [PMID: 27878543 DOI: 10.1007/s11325-016-1436-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2016] [Revised: 10/10/2016] [Accepted: 11/06/2016] [Indexed: 12/20/2022]
Abstract
BACKGROUND Numerous mathematical formulas have been developed to determine continuous positive airway pressure (CPAP) without an in-laboratory titration study. Recent studies have shown that style of CPAP mask can affect the optimal pressure requirement. However, none of the current models take mask style into account. Therefore, the goal of this study was to develop new predictive models of CPAP that take into account the style of mask interface. METHODS Data from 200 subjects with attended CPAP titrations during overnight polysomnograms using nasal masks and 132 subjects using oronasal masks were randomized and split into either a model development or validation group. Predictive models were then created in each model development group and the accuracy of the models was then tested in the model validation groups. RESULTS The correlation between our new oronasal model and laboratory determined optimal CPAP was significant, r = 0.61, p < 0.001. Our nasal formula was also significantly related to laboratory determined optimal CPAP, r = 0.35, p < 0.001. The oronasal model created in our study significantly outperformed the original CPAP predictive model developed by Miljeteig and Hoffstein, z = 1.99, p < 0.05. The predictive performance of our new nasal model did not differ significantly from Miljeteig and Hoffstein's original model, z = -0.16, p < 0.90. The best predictors for the nasal mask group were AHI, lowest SaO2, and neck size, whereas the top predictors in the oronasal group were AHI and lowest SaO2. CONCLUSION Our data show that predictive models of CPAP that take into account mask style can significantly improve the formula's accuracy. Most of the past models likely focused on model development with nasal masks (mask style used for model development was not typically reported in previous investigations) and are not well suited for patients using an oronasal interface. Our new oronasal CPAP prediction equation produced significantly improved performance compared to the well-known Miljeteig and Hoffstein formula in patients titrated on CPAP with an oronasal mask and was also significantly related to laboratory determined optimal CPAP.

Abstract
Continuous positive airway pressure (CPAP) is the gold standard for the treatment of obstructive sleep apnea (OSA). Although CPAP was originally applied with a nasal mask, various interfaces are currently available. This study reviews theoretical concepts and questions the premise that all types of interfaces produce similar results. We revised the evidence in the literature about the impact that the type of CPAP interface has on the effectiveness of and adherence to OSA treatment. We searched the PubMed database using the search terms "CPAP", "mask", and "obstructive sleep apnea". Although we identified 91 studies, only 12 described the impact of the type of CPAP interface on treatment effectiveness (n = 6) or adherence (n = 6). Despite conflicting results, we found no consistent evidence that nasal pillows and oral masks alter OSA treatment effectiveness or adherence. In contrast, most studies showed that oronasal masks are less effective and are more often associated with lower adherence and higher CPAP abandonment than are nasal masks. We concluded that oronasal masks can compromise CPAP OSA treatment adherence and effectiveness. Further studies are needed in order to understand the exact mechanisms involved in this effect.

Abstract
PURPOSE It is known that oronasal masks are not as effective at opening the upper airway compared to nasal only continuous positive airway pressure (CPAP) masks in patients with sleep-disordered breathing. However, the physiological mechanism for this difference in efficacy is not known; although, it has been hypothesized to involve the retroglossal and/or retropalatal region of the upper airway. The objective of this study was to investigate differences in retroglossal and retropalatal anterior-posterior space with the use of oronasal vs. nasal CPAP masks using real-time cine magnetic resonance imaging (cMRI). METHODS Ten subjects (eight men, two women) with obstructive sleep apnea (OSA) were given cMRI with both nasal and oronasal CPAP masks. Each subject was imaged with each interface at pressures of 5, 10, and 15 cm of H2O, while in the supine position along the sagittal plane. RESULTS The oronasal mask produced significantly less airway opening in the retropalatal region of the upper airway compared to the nasal mask interface. During exhalation, mask style had a significant effect on anterior-posterior distance p = 0.016. No differences were found in the retroglossal region between mask styles. CONCLUSIONS Our study confirmed previous findings showing differences in treatment efficacy between oronasal and nasal mask styles. We have shown anatomic evidence that the nasal mask is more effective in opening the upper airway compared to the oronasal mask in the retropalatal region.

Abstract
BACKGROUND In some individuals with obstructive sleep apnea (OSA), oronasal continuous positive airway pressure (CPAP) leads to poorer OSA correction than nasal CPAP. The authors hypothesized that this results from posterior mandibular displacement caused by the oronasal mask. OBJECTIVE To test this hypothesis using a mandibular advancement device (MAD) for mandibular stabilization. METHODS Subjects whose OSA was not adequately corrected by oronasal CPAP at pressures for which nasal CPAP was effective were identified. These subjects underwent polysomnography (PSG) CPAP titration with each nasal and oronasal mask consecutively, with esophageal pressure and leak monitoring, to obtain the effective pressure (Peff) of CPAP for correcting obstructive events with each mask (maximum 20 cmH2O). PSG titration was repeated using a MAD in the neutral position. Cephalometry was performed. RESULTS Six subjects with mean (± SD) nasal Peff 10.4±3.0 cmH2O were studied. Oronasal Peff was greater than nasal Peff in all subjects, with obstructive events persisting at 20 cmH2O by oronasal mask in four cases. This was not due to excessive leak. With the MAD, oronasal Peff was reduced in three subjects, and Peff <20 cmH2O could be obtained in two of the four subjects with Peff >20 cmH2O by oronasal mask alone. Subjects' cephalometric variables were similar to published norms. CONCLUSION In subjects with OSA with higher oronasal than nasal Peff, this is partially explained by posterior mandibular displacement caused by the oronasal mask. Combination treatment with oronasal mask and MAD may be useful in some individuals if a nasal mask is not tolerated.

Abstract
PURPOSE The purpose of this study was to compare the therapeutic pressure determined by an automated CPAP device (AutoCPAP) during the titration period, between nasal and oronasal mask and the residual apnea-hypopnea index (AHI) on a subsequent poligraphy performed with the established therapeutic CPAP. METHODS As a retrospective study, 109 subjects with moderate and severe obstructive sleep apnea-hypopnea (apnea-hypopnea index≥15 events/h) were studied. CPAP titration was performed using an auto-titrating device. RESULTS There was significant difference in the mean pressure delivered with autoCPAP between the group of patients using the nasal mask (mean 10.0 cmH2O±2.0 SD) and the group which used the oronasal mask (mean 11.2 cmH2O±2.1) (p<0.05). Residual apneas were lower when using a nasal mask: average AHI of 2.6±2.5 compared to 4.5±4.0 using an oronasal mask (p<0.05). On multivariate analysis, the only independent predictor of the level of therapeutic pressure of CPAP was the type of mask used (r=0.245, p 0.008). CONCLUSIONS Therapeutic CPAP level for OSAH is higher when administered via oronasal mask, leaving more residual events. These findings suggest that nasal mask should be the first choice for OSAH treatment.

Abstract
INTRODUCTION It has been found that mask style can affect the amount of continuous positive airway pressure (CPAP) required to reduce an apnoea/hyponoea index (AHI) to < 5/h on a titration study. However, it was not previously known whether switching from one CPAP mask style to another post titration could affect the residual AHI with CPAP. The purpose of this study was to investigate the differences in residual AHI with CPAP treatment between oronasal and nasal masks. METHODS Twenty-one subjects (age mean (M)=62.9, body mass index (BMI) M=29.6 kg/m2) were randomised (14 subjects completed the protocol) to undergo an in-laboratory CPAP titration with either a nasal mask or an oronasal mask. Subjects were then assigned this mask for 3weeks of at-home CPAP use with the optimal treatment pressure determined on the laboratory study (CPAP M=8.4 cm of H2O). At the end of this 3-week period, data were collected from the CPAP machine and the subject was given the other mask to use with the same CPAP settings for the next 3weeks at home (if the nasal mask was given initially, the oronasal one was given later and vice versa). On completion of the second 3-week period, data on residual AHI were again collected and compared with the first 3-week period on CPAP. RESULTS A Wilcoxon Signed-Rank Test (two-tailed) revealed that residual AHI with CPAP treatment was significantly higher with the oronasal compared with the nasal mask (z = -3.296, p<0.001). All 14 subjects had a higher residual AHI with the oronasal versus nasal mask, and 50% of the subjects had a residual AHI >10/h in the oronasal mask condition, even though all of these subjects were titrated to an AHI of < 5/h in the laboratory. CONCLUSION A higher residual AHI was seen in all patients with the use of an oronasal mask compared with a nasal mask. Switching to an oronasal mask post titration results in an increase in residual AHI with CPAP treatment, and pressure adjustment may be warranted.

Abstract
RATIONALE In obstructive sleep apnea patients (OSA), continuous positive airway pressure (CPAP) adherence is crucial to improve symptoms and cardiometabolic outcomes. The choice of mask may influence CPAP adherence but this issue has never been addressed properly. OBJECTIVE To evaluate the impact of nasal pillows, nasal and oronasal masks on CPAP adherence in a cohort of OSA. METHODS Newly CPAP treated OSA participating in "Observatoire Sommeil de la Fédération de Pneumologie", a French national prospective cohort, were included between March 2009 and December 2011. Anthropometric data, medical history, OSA severity, sleepiness, depressive status, treatment modalities (auto-CPAP versus fixed pressure, pressure level, interface type, use of humidifiers) and CPAP-related side effects were included in multivariate analysis to determine independent variables associated with CPAP adherence. RESULTS 2311 OSA (age = 57(12) years, apnea+hypopnea index = 41(21)/h, 29% female) were included. Nasal masks, oronasal masks and nasal pillows were used by 62.4, 26.2 and 11.4% of the patients, respectively. In univariate analysis, oronasal masks and nasal pillows were associated with higher risk of CPAP non-adherence. CPAP non-adherence was also associated with younger age, female gender, mild OSA, gastroesophageal reflux, depression status, low effective pressure and CPAP-related side effects. In multivariate analysis, CPAP non-adherence was associated with the use of oronasal masks (OR = 2.0; 95%CI = 1.6; 2.5), depression, low effective pressure, and side effects. CONCLUSION As oronasal masks negatively impact on CPAP adherence, a nasal mask should be preferred as the first option. Patients on oronasal masks should be carefully followed.
