The CPAP machine records data and upload it to a website you can track. This is a screenshot of the app I downloaded with my data from my nap this afternoon. My sleep study said I had 86 events per hour, so three is much better. The sleep study track snoring episodes though too, as well as low oxygen levels, so there is a bit of a different comparison here.
My insurance is paying the monthly rental fee for 10 months, and then I own it out right. But since this tracks usage, you have to demonstrate compliance with it or they stop paying. I believe compliance is six hours a day for 21 days a month.
If you feel you're not sleeping well or are chronically fatigued, John we consider getting a sleep study.
I'm not sure if your insurance is different, but mine requires the same regulations as DOT which is at least 4 hrs per night and 70% of the days (which I think comes out to 20-21 days per month).
