you have data (according to your sig) from the machine available in multiple programs, instead of assuming that it was an apnea, why don't you check the data and see what it says.
What else would it be? What besides an apnea causes a heart rate spike concurrent with a sharp O2 dip?
It is easy to find the time because I pulled the hose of the mask to go take a pee when I woke up. My machine is set for auto-shutoff when the hose is disconnected so Sleepy Head and ResScan marked the time of awakening. There is nothing out of the ordinary recorded by SleepyHead or ResScan before the awakening and the time of the event that the oximeter captured immediately before awakening.
I am still puzzled by your replies.

Cryptic replies can be tough to understand I agree...

Realizing I am *NOT* a doctor, I would say a large number of different things *could* cause the above, and if you can't prove it to be an OSA-related event, and if it happens again, I would strongly think about discussing this with my doctor.
A heart 'event' could cause the O2 drop - besides it being the other way round. Just a thought? Classic 'CHF' issue (Congestive Heart Failure) - please note - a thousand different issues could be the cause, as well as just a random issue.
:I have had all kinds of heart tests done and passed with flying colors. I am pretty fit for age 68. A couple weeks ago I did a 110 mile bike ride in 90* Texas heat. I ride my bike 100+ miles a week with young "roadies," so it is not like I should be expected to huff and puff getting out of bed to walk to the pee-pot.
I am going to:
A: Try to sync the clocks on the pulse oximeter and the CPAP tighter. But the pulse oximeter clock doesn't keep time great.
B: Keep comparing the two.
Last night I had greater pressure on the CPAP and it blew a lot of leaks. The pulse oximeter reading showed far fewer events than the CPAP -- the opposite of what had been happening.
