Is it still working?

Sorry i meant to ask does the postition i lie in effect RERA readings. I do find if i lie on my back that my AHI readings are definately impacted.

The basics are simple. Breathing can range from
1. completely normal with no restrictions
2. Flow limits w up to 50% restrictions to
3. Hypopneas w up to 80% restrictions to
4. Apnea w 80 to 100% restriction.
CPAPs can't measure restrictions so they measure flows to determine how restricted the flow is.
RERAs are a series of flow limitations ending in arousal. Respiratory Effort Related Arousal.
RDI = AHI + RERAs
UARS, Upper Airway Respiratory Syndrome is Med#peak for flow limits
