The effects of continuous positive airway pressure (CPAP) on the metabolic cost and work of breathing at rest, and during exercise, in healthy individuals wearing a gas mask

Ventilation may limit exercise. Wearing a gas mask may further compromise ventilation by increasing airway resistance. Continuous positive airway pressure (CPAP) improves ventilation by reducing airway resistance. The purpose of this study is to investigate the effects of a gas mask with and without CPAP on pattern, metabolic cost, and work of breathing (WOB) during resting and exercise conditions. We hypothesize that in healthy individuals, a …
