31. Does continuous positive airway pressure treatment affect autonomic nervous system in patients with severe obstructive sleep apnea?

To evaluate whether Continuous Positive Airway Pressure treatment (CPAP) affect autonomic nervous system (ANS) in patients with severe obstructive sleep apnea (OSAS). We compared de novo OSAS patients, OSAS patients on chronic CPAP treatment and controls using the Scales for Outcome in Parkinson disease-Autonomic (SCOPA-AUT) questionnaire. All groups underwent autonomic function tests including head-up tilt test (HUTT), Valsalva maneuver, deep breathing, handgrip and cold face test. Twelve untreated OSAS, 17 OSAS on CPAP and 14 controls were studied.
