Introduction: Catathrenia is a rare, idiopathic, sleep-related respiratory condition characterized by irregular groans, which occur during prolonged expiration in sleep. The origins of Catathrenia remain inexplicable and the long-term prognosis unexplained.

Case Report: We report a case of Catathrenia with concurrent Obstructive Sleep Apnea complicated with pulmonary hypertension and treat the case with Continuous Positive Airway Pressure (CPAP).

Discussion: Treatment with Nasal CPAP resulted in marked improvement of Catathrenia obstructive sleep apnea, daytime dyspnea and respiratory failure for our patient. We think that nasal continuous positive airway pressure can be an option for the treatment of this case and more better outcomes on Dyspnea and respiratory failure are expected if done on large population with periodic follow up.
