After starting on CPAP I had improved a great deal but was still spending long periods awake every night. After reading this thread and seeing GratUncleBill's suggestion for getting an inexpensive pulse oximeter I purchased the CMS-50F and started recording my nights. Even though last night was night three for recording I can already see a pattern of events where my O2 levels drop way down to 80, and occasionally below, leading up to the timeframe I am typically awake. I can tell from looking at the chart when and how long I am awake since the O2 levels are stable. Another interesting part to the graphs is where my pulse rate will shoot up over 120 at least once a night; bad dream?
It will be interesting to show the doctor what this little device is coming up with and see what he might have to say. Wish I had a CPAP machine that would record data instead of the brick I bought.
