Your apnea events were down to 14 per hour, a 38% improvement from the baseline you set in the home sleep test two weeks ago. Your overnight blood oxygen stayed above 92% for 96% of the night, and your heart rate variability (HRV) is the highest it has been in 30 days.
Three things drove the change: you used your oral appliance for the full night (first time this month), you slept on your right side 84% of the time, and your evening alcohol intake was zero. Stick with this combination tonight.
Cardiovascular. Your overnight HRV reaching 52ms is meaningful. Sustained HRV in this range is associated with a measurable reduction in cardiovascular event risk over time. Your resting heart rate at 58 bpm is consistent with someone whose autonomic nervous system is recovering rather than under chronic stress.
Metabolic. Your continuous glucose monitor (Dexcom G7) registered an overnight average of 96 mg/dL with no nocturnal excursions above 140. Apnea events typically drive overnight glucose spikes via cortisol release. Your reduced event count last night correlates directly with this glucose stability.
Cognitive / Alzheimer's risk. Deep sleep at 1h 48m clears amyloid via the glymphatic system. Below 1h is the threshold associated with cognitive risk in the literature. You are well above that. Continued nights at this level over months is the protective signal we are tracking.
