Abstract
Oxygen therapy is the first-line treatment for hypoxemic acute respiratory failure. In veterinary medicine this has traditionally been provided via mask, low-flow nasal oxygen cannulas, oxygen cages and invasive positive pressure ventilation. Traditional non-invasive modalities are limited by the maximum flow rate and fraction of inspired oxygen (FiO2) that can be delivered, variability in oxygen delivery and patient compliance. The invasive techniques are able to provide higher FiO2 in a more predictable manner but are limited by sedation/anesthesia requirements, potential complications and cost. High-flow nasal oxygen therapy (HFNOT) represents an alternative to conventional oxygen therapy. This modality delivers heated and humidified medical gas at adjustable flow rates, up to 60 L/min, and FiO2, up to 100%, via nasal cannulas. It has been proposed that HFNOT improves pulmonary mechanics and reduces respiratory fatigue via reduction of anatomical dead space, provision of low-level positive end-expiratory pressure (PEEP), provision of constant FiO2 at rates corresponding to patient requirements and through improved patient tolerance. Investigations into the use of HFNOT in veterinary patients have increased in frequency since its clinical use was first reported in dogs with acute respiratory failure in 2016. Current indications in dogs include acute respiratory failure associated with pulmonary parenchymal disease, upper airway obstruction and carbon monoxide intoxication. The use of HFNOT has also been advocated in certain conditions in cats and foals. HFNOT is also being used with increasing frequency in the treatment of a widening range of conditions in humans. Although there remains conflict regarding its use and efficacy in some patient groups, overall these reports indicate that HFNOT decreases breathing frequency and work of breathing and reduces the need for escalation of respiratory support. In addition, they provide insight into potential future veterinary applications. Complications of HFNOT have been rarely reported in humans and animals. These are usually self-limiting and typically result in lower morbidity and mortality than those associated with invasive ventilation techniques.

Abstract
Respiratory failure from tick paralysis (TP) is an important cause of mortality in cats and dogs in Australia, occurring from a combination of respiratory muscle paralysis, upper respiratory tract obstruction and pulmonary disease. Patients may require positive-pressure ventilation in management of any combination of hypoxemia, hypoventilation or respiratory fatigue, but may also require airway management due to laryngeal paralysis. No single ventilation strategy is recommended due to the heterogenous disease presentations. Lung protective ventilation should be used in patients with pulmonary disease. Due to local and systemic effects of TP, patients are at higher risk of complications such as aspiration pneumonia and corneal ulceration and may have additional intravenous fluid and nutritional considerations. Treatment with hyperimmune serum is associated with improved outcomes. Prognosis is considered good with documented survival to discharge (STD) of 52.6-77% for animals with TP ventilated with lung disease and 90.5% for animals without lung disease. Median reported duration of ventilation for TP ranges from 23 to 48 h (range 3 h-10 days). The severity of individual neuromuscular signs and the presence of associated conditions such as aspiration pneumonia and laryngeal paralysis may necessitate longer periods of mechanical ventilation. This review aims to summarize the current recommendations regarding indications, management and prognosis of cats and dogs undergoing MV for TP and to identify areas for future research.

Abstract
OBJECTIVE To describe the transportation and clinical outcome of 9 dogs transported to a referral hospital on mechanical ventilation (MV). DESIGN Retrospective case series (2015-2020). SETTING University teaching hospital. ANIMALS Nine dogs transported to a referral center on MV. INTERVENTIONS All dogs underwent MV during vehicular transport. MEASUREMENT AND MAIN RESULTS The medical records of 9 dogs transported on a MV to a university teaching hospital were reviewed. Data collected included signalment, reason for MV, ventilator settings, sedation protocol, monitoring in transit, distance traveled, complications, clinical outcome, and cost. All dogs transported survived transport to the referral hospital and 8 of 9 were successfully weaned from the ventilator and discharged home. CONCLUSIONS MV during transport in this setting was practical and safe. Dogs in this study had a high survival rate compared to previous studies of dogs undergoing MV, likely due to selection of cases assessed to have a correctable underlying disease.

Abstract
OBJECTIVE A prospective clinical trial was performed to evaluate the efficacy and tolerance of high-flow nasal cannula (HFNC) in dogs with hypoxemia. ANIMALS 20 client-owned dogs failing conventional oxygen therapy (COT). PROCEDURES Patients admitted to the ICU for treatment of hypoxemic respiratory failure were enrolled in the study. PaO2, SPO2, respiratory rate (RR), and acute patient physiologic and laboratory evaluation scores were obtained at the time of COT failure and after initiation of HFNC. Complications and patient tolerance while receiving HFNC were also recorded. RESULTS Compared to COT, the median PaO2 and SO2 were significantly higher when dogs were receiving HFNC (60.8 vs 135.6 mm Hg and 90.7% vs 99.25%, respectively). Dogs receiving HFNC had a significant reduction in median RR as compared to dogs undergoing COT (52 vs 36 breaths per minute). After the initiation of HFNC, all dogs showed clinical improvement as measured by PaO2, SO2, and RR. Of 20 dogs, 6 ultimately failed HFNC and mechanical ventilation was recommended. Nine dogs undergoing HFNC survived to discharge, and acute patient physiologic and laboratory evaluation scores had a significant positive severity correlation with death. Complications included pneumothorax in 1 dog. CLINICAL RELEVANCE COT has limited flow rates due to airway irritation caused by room temperature, nonhumidified oxygen. HFNC uses vapor humidification and heated oxygen, allowing for higher flow rates. In people, HFNC is used as escalation of oxygen therapy when COT fails. Dogs treated with HFNC had significant improvements in PaO2, SO2, and RR as compared to COT. HFNC is well tolerated and effective in treating hypoxemia in dogs.

Abstract
OBJECTIVE To compare the short- and long-term outcomes of dogs and cats with left-sided congestive heart failure (L-CHF) undergoing positive pressure ventilation (PPV) to patients undergoing PPV for other causes and to determine risk factors associated with outcomes in this population. DESIGN This retrospective study included dogs and cats that underwent PPV during 2018-2020. The study group included patients diagnosed with L-CHF. The control group included patients who were ventilated for reasons other than L-CHF. The risk factors evaluated included vital signs on presentation, ventilator settings, development of azotemia during hospitalization, cardiopulmonary resuscitation (CPR), complications, and medications used. SETTING University Teaching Hospital. ANIMALS Fifty (32 dogs, 18 cats) study group animals and 51 (39 dogs, 12 cats) control group animals were included in the L-CHF and control groups, respectively. MEASUREMENTS AND MAIN RESULTS Sixty-six percent (33/50) of L-CHF patients, compared with 35% (18/51) of the control patients, were weaned off PPV (P = 0.002). Fifty-four percent (27/50) of the L-CHF patients survived to discharge, compared with 26% (13/51) of the control group patients (P = 0.003). However, only 54% (12/22) of the discharged L-CHF patients survived for >2 months compared to 100% of the control patients. The median survival time for dogs and cats with L-CHF surviving to discharge was 240 days (range: 1-730 days). In dogs, factors negatively associated with survival included CPR in both groups and the development of azotemia in the L-CHF group. Anemia on presentation was negatively associated with survival for both cats and dogs in the control group. CONCLUSIONS Dogs and cats undergoing PPV due to L-CHF were more commonly weaned off the ventilator and survived to discharge compared to other causes necessitating PPV. However, these patients suffer from severe heart disease, and therefore, their long-term survival is guaranteed.

Abstract
OBJECTIVES To determine the complications associated with positive-pressure ventilation (PPV) in dogs and cats. DESIGN Retrospective study from October 2009 to September 2013. SETTING University Teaching Hospital. ANIMALS Fifty-eight dogs and 9 cats. MEASUREMENTS AND MAIN RESULTS Medical records were retrospectively reviewed; signalment, complications associated with PPV, duration of PPV, and outcome were recorded. Complications most commonly recorded during PPV included hypothermia 41/67 (61%), hypotension 39/67 (58%), cardiac arrhythmias 33/67 (49%), a positive fluid balance 31/67 (46%), oral lesions 25/67 (37%), and corneal ulcerations 24/67 (36%). A definition of ventilator-associated events (VAE) extrapolated from the Center of Disease Control's criteria was applied to 21 cases that received PPV for at least 4 days in this study. Ventilator-associated conditions occurred in 5 of 21 (24%) of cases with infection-related ventilator-associated conditions and ventilator-associated pneumonia identified in 3 of 21 (14%) cases. CONCLUSIONS Complications are common and diverse in dogs and cats receiving long-term PPV and emphasizes the importance of intensive, continuous patient monitoring and appropriate nursing care protocols. Many of the complications identified could be serious without intervention and suggests that appropriate equipment alarms could improve patient safety. Development of veterinary specific surveillance tools such as the VAE criteria would aid future investigations and allow for effective multicenter studies.

Abstract
OBJECTIVE To describe the clinical characteristics and outcomes in a population of dogs with negative-pressure pulmonary edema (NPPE) and to identify the main causes of the disease. To evaluate any associations with morbidity and mortality. DESIGN Retrospective study. SETTING Three university teaching hospitals and 2 private referral centers in the United Kingdom. ANIMALS Thirty-five client-owned dogs presented with NPPE. INTERVENTIONS None MEASUREMENTS AND MAIN RESULTS: Data collected included patient characteristics, clinical history, clinicopathological abnormalities, radiographic features, treatments, and outcomes. The median age was 4 months (range 2-90) and median weight was 7.1 kg (range 1.7-37.2). There were many causes of NPPE including leash tugs, near hanging, accidental choking, anatomical obstruction to airflow, and purposeful airway obstruction by people. The most common cause of NPPE was accidental choking (40% of cases). Dogs with an anatomical obstruction were older than 24 months. Hypoxemia with an increased alveolar-arterial gradient was common on presentation. The majority of thoracic radiographs (65.7%) showed an alveolar or interstitial pattern in the caudodorsal area as previously described in the literature. Oxygen therapy was administered to 33 (94.3%) dogs. Furosemide was administered to 18 (51.4%) dogs. The median length of hospitalization was 2 days (range 0-14). Twenty-eight (80%) dogs survived to discharge. Seven dogs were mechanically ventilated and only 2 of them (28.6%) survived to discharge. The requirement for mechanical ventilation was the only parameter associated with mortality (P < 0.001). CONCLUSIONS Most cases of NPPE occur in juvenile dogs. Different incidents associated with upper airway obstruction can produce an episode of NPPE. Choking on food or toys and near hanging have not been previously described in the veterinary literature as inciting causes of NPPE. The overall prognosis is good.

Abstract
BACKGROUND Mechanical ventilation is frequently performed in small animal critical care medicine with well-documented survival data; quality of life in these patients following discharge from hospital is unknown. KEY FINDINGS Owners of patients surviving to discharge following mechanical ventilation were surveyed with an open ended and ranking score questionnaire. Response rate was 57% (27/47). All respondents rated their pet's quality of life prior to the illness necessitating ventilation as good to excellent (8/10-10/10). Perceived recovery periods ranged from 0 days to 6 months (the most common response being 2-3 weeks). Fourteen owners stated that their pets' quality of life was as good or better than previously. Patients with persistent quality of life concerns (n = 3) had been ventilated for neurological disease. Four owners reported changed behaviors such as startling easily or being excessively responsive to noise. One cat became deaf and at time of survey had not regained hearing. Commonly reported problems included decreased exercise tolerance (n = 3). All respondents stated that they would ventilate their pet again. SIGNIFICANCE Cats and dogs that are mechanically ventilated appear to recover with minimal adverse effect on their quality of life. Patients ventilated for neurological conditions may be more likely to experience quality of life limitations.

Abstract
OBJECTIVE To describe patient recovery in dogs that had undergone mechanical ventilation (MV) and received atracurium as a continuous rate infusion (CRI). CASE SERIES SUMMARY Three dogs were treated with atracurium CRI while mechanically ventilated and were successfully weaned. All were pediatric patients (2-3 months old) ventilated due to respiratory fatigue and hypoxemia. All dogs experienced seizure activity in the initial 24 h following extubation and were treated with various anticonvulsant protocols; no patients experienced documented seizures after 48 h of discontinuation from MV. NEW OR UNIQUE INFORMATION PROVIDED All three successfully weaned dogs that had received an atracurium CRI experienced new onset seizures in their recovery from MV. Atracurium use in long-term MV has not been described previously, and seizures in dogs following atracurium administration has not been described in the clinical setting. Although causation cannot be proven in this case series, atracurium use should be carefully considered and be monitored appropriately when used for a prolonged duration.

Abstract
This report, issued by the ACVIM Specialty of Cardiology consensus panel, revises guidelines for the diagnosis and treatment of myxomatous mitral valve disease (MMVD, also known as endocardiosis and degenerative or chronic valvular heart disease) in dogs, originally published in 2009. Updates were made to diagnostic, as well as medical, surgical, and dietary treatment recommendations. The strength of these recommendations was based on both the quantity and quality of available evidence supporting diagnostic and therapeutic decisions. Management of MMVD before the onset of clinical signs of heart failure has changed substantially compared with the 2009 guidelines, and new strategies to diagnose and treat advanced heart failure and pulmonary hypertension are reviewed.

Abstract
BACKGROUND Pancreatitis in cats (FP) has been increasingly diagnosed in recent years, but clinical studies of large numbers of affected cats are scarce. OBJECTIVES To describe a large cohort of cats with FP requiring hospitalization. ANIMALS One hundred and fifty-seven client-owned cats. METHODS Retrospective study, including cats diagnosed with pancreatitis based on sonographic evidence, positive SNAP feline pancreatic lipase immunoreactivity test results, increased 1,2-o-dilauryl-rac-glycerol-glutaric Acid-(6'-methylresorufin ester)-lipase activity, histopathology, or some combination of these. RESULTS One-hundred and twenty-two cats (77.7%) survived to discharge. Median time from onset of clinical signs to presentation was longer (P = .003) in nonsurvivors. Causes of FP included recent general anesthesia, trauma, hemodynamic compromise, and organophosphate intoxication, but most cases (86.6%) were idiopathic. Ultrasonographic findings consistent with pancreatitis were documented in 134 cats, including pancreatomegaly (81.3%), decreased (31.3%), or increased (14.9%) pancreatic echogenicity, extra-hepatic biliary tract dilatation (24%), and increased peri-pancreatic echogenicity (13%). Lethargy (P = .003), pleural effusion (P = .003), hypoglycemia (P = .007), ionized hypocalcemia (P = .016), azotemia (P = .014), parenteral nutrition administration (P = .013), and persistent anorexia during hospitalization (P = .001) were more frequent in nonsurvivors, whereas antibiotics were more frequently administered to survivors (P = .023). Nevertheless, when Bonferroni's correction for multiple comparisons was applied, none of the variables was statistically significant. CONCLUSIONS AND CLINICAL IMPORTANCE Previously unreported, clinically relevant, potential prognostic factors, including hypoglycemia, azotemia, parenteral nutrition, and withholding antibacterial treatment were identified in this exploratory study. These preliminary results should be examined further in confirmatory studies.

Abstract
OBJECTIVE To retrospectively determine the population and outcome characteristics of a cohort of Australian elapid snake envenomed cats requiring mechanical ventilation (MV). DESIGN Retrospective observational study (2005-2014). SETTING Academic veterinary emergency and critical care service. ANIMALS Twelve cats undergoing MV for elapid snake envenomation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The medical records were searched to identify cats requiring MV as part of treatment for elapid snake envenomation. Signalment, the indication for, duration of and complications associated with MV, duration of hospitalization, and survival to hospital discharge were recorded for each of the enrolled cases. Seven cats (58.3%) underwent MV because of presumed unsustainable respiratory effort and 5 cats (41.7%) for respiratory arrest. Eleven cats (91.7%) were successfully weaned from MV and survived to hospital discharge. No cats developed ventilator associated pneumonia or pneumothorax. The median duration of MV was 19.5 hours for the survivors (range 7.0-37.0 hours) and median duration of hospitalization was 3.5 days (range 2.4-14.9 days). CONCLUSIONS Cats requiring MV for elapid snake envenomation have a favorable outcome and require a relatively short period of MV. Complications encountered are unlikely to influence outcome.
