Compared to sole HFNC, additional intervention with upper body elevation significantly decreased AHI-flow by 11.5
events.hour-1 (1.7 to 21.4, 95% CI) (p=0.022).

Background anthropometric and surgical characteristics did not differ between the groups. Preoperative apnea hypopnea index determined by both flow signal and Spo2 criteria was significantly greater in the flatbed/HOB30 group compared to the HOB30/flatbed group.
All participants underwent two preoperative sleep studies. First, at home on a flatbed and second, in the hospital on a HOB30 bed. Furthermore, two postoperative sleep studies were planned on N1 and N2 on the bed with different head-of-bed positions.
none
The primary outcome of this study was the modified apnea hypopnea index measured by the sleep study based exclusively on the air flow signal without Spo2 criteria (AHI-flow). The secondary outcomes included all sleep study variables described above characterizing severity and nature of OSA.
