The Performance of Two Automatic Servo-Ventilation Devices in the Treatment of Central Sleep Apnea

1693 AutoSV Devices in the Treatment of CSA—Javaheri et al ther by clinical judgment or automatically, and, if spontaneous breathing does not occur within that specific time frame, a mandated breath is delivered to abort any impending apnea. In the present study, we evaluated a new generation advanced adaptive-servo ventilator (BiPAP autoSV Advanced, Philips Respironics) in which the EPAP is adjusted automatically by algorithms aimed at correcting obstructive disordered breathing events in addition to other features aimed at treating CSA. Our primary aim was to compare the performance of the advanced servo-ventilator (BiPAP autoSV Advanced) with conventional servo-ventilator (BiPAP autoSV) in treating CSA. In order to address this aim we performed a randomized, doubleblind, crossover study. The preliminary results of this study have been published in the abstract form.23
