Physiological Study of the Critical Closing Airway Pressure in a Population of Didgeridoo Players

Obstructive sleep apnea is characterised by an abnormal upper airway collapsibility. Upper airway collapsibility can be evaluated through critical closure airway pressure (Pcrit). Didgeridoo is a traditional australian musical instrument involving circular respiration, a breathing technique involving mouth muscles. We hypothesize that didgeridoo players have a lower risk of airway collapsibility due to circular breathing technique
