Impact of wearing a surgical facemask during exercise on dyspnea in patients with chronic pulmonary infections: A randomized crossover study. Respir Med 2023; 220:107453. [PMID: 37993025 DOI: 10.1016/j.rmed.2023.107453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 10/25/2023] [Accepted: 10/30/2023] [Indexed: 11/24/2023]
Abstract
BACKGROUND Wearing facemasks in public is effective in preventing viral transmission. However, no study has evaluated the impact of wearing facemasks during exercise on dyspnea in patients with chronic pulmonary infections from multifaceted aspects, including sensory qualities and emotional responses. The aim of this study was to evaluate facemask-related dyspnea during exercise in this patient population. METHODS We conducted a randomized crossover study involving adult patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD) or bronchiectasis who participated in exercise sessions, both with (mask-on) and without (mask-off) surgical facemasks. The sensory and emotional dimensions of dyspnea during each exercise session were assessed using the Multidimensional Dyspnea Profile. Statistical analyses were performed to identify factors associated with worsening scores for each dimension. RESULTS Thirty-four patients (mean age [standard deviation]: 71.6 [8.6] years) were included in the analysis. The median [interquartile range] total scores for the sensory and emotional dimensions of dyspnea were 3.5 [1, 9.5] (mask-off) vs. 10 [5.5, 23.8] (mask-on) (P < 0.001) and 0 [0, 5] (mask-off) vs. 3 [0.8, 10.3] (mask-on) (P = 0.115), respectively. "Air hunger" was the primary sensory descriptor of mask-related dyspnea. Vital capacity (VC) < 80% of the predicted value was a significant risk factor for worsening sensory dimension scores when wearing masks (odds ratio [95% confidence interval]: 5.5 [1.16-26.1], P = 0.038). CONCLUSIONS The findings of this study indicate that patients with NTM-PD or bronchiectasis, particularly those with VC <80% of the predicted value, are likely to experience the sensory dimension of dyspnea during exercise while wearing surgical facemasks.

Abstract
Walking is a vital component of physical activity in patients with chronic obstructive pulmonary disease (COPD). Exertional multidimensional breathlessness in daily life can reduce walking speed and time in patients with established COPD [1]. Improvement in breathlessness beyond a minimal clinically significant difference brought about by pulmonary rehabilitation, pharmaceutical bronchodilators and opioids has been reported [2–4]. However, despite guideline-directed disease-specific therapy, some patients with COPD experience residual breathlessness. Therefore, the application of a novel symptom-based treatment that is widely available will benefit patients with long-term breathlessness. l-Menthol is a novel treatment option for breathlessness in patients with COPD. However, the clinical application of menthol for the treatment of exertional breathlessness in these patients warrants further research.https://bit.ly/3D6rLiJ
