Abstract: Positive airway pressure (PAP) therapy is known to be an effective treatment for obstructive sleep apnea (OSA) that does not generally have serious complications. However, pneumothorax following lung barotrauma with the use of PAP has rarely been reported. We recently experienced the case of a 72-year old male patient with chronic obstructive pulmonary disease who developed pneumothorax after the use of automatic PAP (APAP). After 4 months of APAP use with a pressure of 4–8 cm H2O, he complained of sudden severe dyspnea at midnight. He eventually underwent surgical repair for pneumothorax. After 4 months, continuous PAP with low pressure of 5 cm H2O was applied without any complications. In summary, we emphasize the risk of barotrauma when PAP is used by OSA patients with lung disease.
