TL;DR: Been using my wife's old CPAP for a few weeks now and am sleeping better -- does this mean I need one?
My wife has OSA, so I'm pretty familiar with it. She recently replaced her Respironics Remstar AUTO (older one with smartcard) with a Resmed S9.
For probably the past year I've had issues with getting a REALLY good night sleep. I wake up often in the night, even if it is just a slight rousing without really opening my eyes and going back to sleep. I've always been a morning person so I wake up no problem. However I'm prone to dozing off in dark meeting rooms at work and I can fall asleep reading or watching TV after work pretty easily. No issues with daily driving; long drives can be a challenge, however.
I'm a 36 yo male, higher BMI, non-smoker. My wife only reports occasional snoring from me. I'm normally a side sleeper.
Since my wife replaced he CPAP I decided to give her old one a try. I set a base pressure of 6cm and max of 18cm with the machine in auto mode.
I've used it for about 3 weeks now and feel MUCH more refreshed in the morning. When I wake up I check the pressure; it's usually still at 6, but can be up to 9 or 10 at times (I realize it will fluctuate over the night).
I also bought a Contec CMS50D pulse oximeter and recorded things for a week without the CPAP, and a week after using the CPAP for a week first. In the SPO2 software I used 3% desat for 10 sec as the
Without CPAP, here is an average night:
With CPAP, here is an average night:
So I'm not dropping below 90 much for O2 saturation, but clearly the CPAP keeps my O2 saturation consistent throughout the night.
I guess I'm not sure if my results without the machine are typical, or if they are indicative that I should pursue seeing a sleep doc.
