Abstract:Aim: to evaluate the acute effects of expiratory positive airway pressure on cardiac autonomic modulation in chronic obstructive pulmonary disease patients during spontaneous breathing and slow deep breathing. Methods: 17 patients were evaluated. The R-R intervals were collected (Polar ® S810i) during spontaneous breathing (10 minutes) and slow deep breathing (4 minutes), with and without 5 cmH 2 O expiratory positive airway pressure. Stable signals were analyzed by Kubios ®. Heart rate variability indices wer… Show more
