Key Takeaway
7.5° head elevation reduced mild-moderate OSA severity by 31.8% on average.
Summary
This study examined how head-of-bed elevation affects obstructive sleep apnea severity in patients with mild to moderate OSA.
Key findings:
- 7.5° incline reduced OSA severity by 31.8% average
- Improved oxygen saturation during sleep
- Reduced apnea-hypopnea index
- May be useful adjunct to other OSA treatments
The researchers note positional therapy (including bed elevation) is an underutilized approach for mild-moderate OSA.
