Interpretation

AHI came in at 0.82, with event mix of 0 OA / 1 H / 1 CA / 0 RERA. Leak_Avg was 0.00 L/min against a 30-day mean of 0.00 L/min.

Total sleep was 6.16 hours with sleep efficiency at 96.5%. Deep sleep held at 20.9% and REM at 16.6%.

Caveats

• Sleep-stage percentages are Apple Watch estimates, not lab EEG.
• Trailing 7d/30d windows include only nights with CPAP data through this date.
• Flags describe deviation from personal baseline, not absolute clinical severity. AHI <5 remains within well-controlled range.
