Critical — requires medical attention
Breathing disturbances avg 43.5 /hr over 3 months (peak 83.7) — 8× above clinical threshold of ≤5. Strongly indicative of severe obstructive sleep apnea.
SpO2 dropping to 62–87% on multiple nights — dangerous oxygen desaturation during sleep.
Deep sleep near zero on 13 of 18 nights — critical physical recovery deprivation.
