Psychological Factors in Noninvasive Home Ventilation Users

Continuous positive airway pressure (CPAP), a noninvasive respiratory therapy technique, is the main treatment for obstructive sleep apnea (OSA). OSA is a common sleep breathing disorder, defined as recurrent episodes of obstructed breathing during sleep. Such episodes cause repeated arousals, sympathetic hyperactivity, and intermittent hypoxia. The influence of OSA on psychological factors is still debatable.
