Randomized Controlled Trial
Performance of conventional and enhanced adaptive servoventilation (ASV) in heart failure patients with central sleep apnea who have adapted to conventional ASV.
Adaptive servo-ventilation (ASV) is a positive pressure ventilator support system to normalize ventilation in patients with Cheyne-Stokes respiration (CSR). The latest generation enhanced ASV device (PaceWave; ResMed) has a new feature--auto-adjustment of EPAP. This study tested the hypothesis that enhanced ASV with auto-adjustment of EPAP (PaceWave) is non-inferior to conventional ASV (AutoSetCS). ⋯ Enhanced ASV is non-inferior to ASV with fixed EPAP in patients with chronic HF and CSR, with a trend towards better control of respiratory events.
