ObjectiveServo ventilation (SV) devices generate positive airway pressure with a variable pressure support that changes in response to a patient’s own respiratory output. Two currently available SV devices—VPAP-AdaptSV® and BIPAP-AutoSV®—have been used in treatment of complex sleep apnea (CompSAS), but no side-by-side comparisons are available.MethodsData of 76 consecutive patients with complex sleep apnea, who were prescribed a VPAP-AdaptSV® or BIPAP-AutoSV® in a non-randomized parallel design, were retrospectively analyzed. Patients underwent a diagnostic polysomnogram followed by a continuous positive airway pressure (CPAP) titration and a SV titration study. Objective compliance with the device was assessed at the first visit at 4–6 weeks of its use.ResultsThirty-five patients received a VPAP-AdaptSV® device, while 41 patients were treated with BIPAP-AutoSV®. Patients treated with BIPAP-AutoSV® had a significantly higher apnea–hypopnea index during their CPAP titration study than patients treated with VPAP-AdaptSV® [49/h (28–60) vs. 35/h (19.5–49.5), median (interquartile range), p < 0.001]. On follow-up, 56 patients (73.7%) were using their device. Mean nightly use was 5.0 h (2.8–6.4) for VPAP-AdaptSV® group and 6.0 h (3.5–7.2) for BIPAP-AutoSV® group (p = 0.081); an improvement in Epworth Sleepiness Scale score was higher in the BIPAP-AutoSV® group than in the VPAP-AdaptSV® group [4 (1–9) vs. 2.5 (0–5), p = 0.02].ConclusionOur retrospective data indicate that the two servo-ventilation devices are comparable means of controlling complex sleep apnea, and the compliance with them is high.
