Samenvatting

Introduction: Positional interventions might be beneficial for patients with positional sleep apnoea (POSA). The aim was to assess the effect of intelligent sleep apnoea beds (ISABel) on OSA severity and sleep fragmentation in POSA.

Method: Adults with POSA (apnoea-hypopnoea-index (AHI) ≥10/h) were eligible. Following a baseline polysomnography, patients were randomly allocated to intervention nights ISABel1 and ISABel2. In case of an apnoea or hypopnoea, ISABel1 elevated the upper body by 50° and ISABel2 induced a one-side bed-inclination of 30° for 10 minutes. Sustained trunk elevations (ISABel1) and position change from supine to non-supine (ISABel2) were successful interventions.

Results: Six men were included. Neither trunk elevation nor side inclination resulted in a significant reduction in AHI. However, only 13% of side inclinations resulted in a successful change into non-supine position. Supine AHI tended to be lower in response to trunk elevations. Non-respiratory related arousals did not change. The time to the next respiratory event following bed movements was longer in ISABel1 than in ISABel2.

Conclusion: Tilting beds might reduce supine AHI and prolong time to the next apnoea/hypopnoea.
