Now that today morning I checked my daily stats in the device. Surprisingly my AHI values are just 0.5 and the 95th percentile pressure in the report is just 11.4. So is it advisable to carry on with the same pressure reading? Or should I change it back to 13.5 again?
When we have an overnight lab titration to determine what our treatment pressure should be, usually we are asked to sleep at least some time on our back, because that is usually the worst case, needing the highest pressure to prevent apneas.
If we can be sure that we are never sleeping flat on our back, our pressure needs will be lower.
So, try to totally avoid sleeping on your back.
Also, I suggest watching three things:
1. How you feel. (Keep notes, if this would help you to remember.)
2. AHI or RDI. The AHI is the Apnea Hypopnea Index, which is the average number per hour of apneas or hypopneas. The RDI is the Respiratory Disturbance Index, which is the average number per hour of apneas or hypopneas or RERAs. RERA means Respiratory Effort-Related Arousal, which is an arousal caused by needing to exert too much effort to breathe.
3. How long are the longest apnea events lasting? (For example, if I was not breathing at all for a whole minute, that would be especially concerning to me and I would definitely mention it to my doctor, who might suggest wearing a "recording" pulse oximeter to see how low my Oxygen level is dropping while asleep.)
