Overnight Pulse Ox Test results, advice please

My sleep/pulmonologist doctor ordered an overnight pulse ox test recently. I wore my CMS-50F both nights while wearing the overnight pulse ox equipment given to me by my doctor.

I dont know what the guidelines are for adding supplemental oxygen. My appt with my doc is in 2 days, I want to go to my appt prepared and ready with information on whats best for my health. I started on Cpap 3rd Aug 2015. The Overnight Pulse Ox tests were done wearing my cpap.

Below is both nights of pulse ox testing reports along with my CMS-50F pulse ox to compare.

Do I need supplemental oxygen? I do drop to 84% some nights while wearing the CMS-50F, thats why the overnight pulse ox was ordered.

I don't see any significant desats in the data. The worst statistic is one minute below 88% and that's not enough to be at all concerned about. Your CPAP treatment is working.

Agree, I don't see any cause for concern about O2 levels.

Now the reason why a pulse ox test was done was because of this data I had a week before.
