Impact of acetazolamide and CPAP on cortical activity in obstructive sleep apnea patients.

ABSTRACT:

Study objectives

1) To investigate the impact of acetazolamide, a drug commonly prescribed for altitude sickness, on cortical oscillations in patients with obstructive sleep apnea syndrome (OSAS). 2) To examine alterations in the sleep EEG after short-term discontinuation of continuous positive airway pressure (CPAP) therapy.

Design

Data from two double-blind, placebo-controlled randomized cross-over design studies were analyzed.

Setting

Polysomnographic recordings in sleep laboratory at 490 m and at moderate altitudes in the Swiss Alps: 1630 or 1860 m and 2590 m.

Patients

Study 1: 39 OSAS patients. Study 2: 41 OSAS patients.

Interventions

Study 1: OSAS patients withdrawn from treatment with CPAP. Study 2: OSAS patients treated with autoCPAP. Treatment w
