Consumer grade oximeters aren't fast enough to indicate the small timespans of desat's the happen anyhow. I talked at length about this with my doctor. I wore a pulse-ox for three nights and when I brought him the data he was UN-impressed. Basically dismissed it as not telling him anything. The only way to know for sure is a PSG.
I have a CMS-60D pulse oximeter. It reads my SpO2 in real time. When I set the alarm to go off at a particular threshold, it goes off as soon as it reached that point. In real time.
The above statement about consumer grade oximeters is not true for my oximeter, and I doubt that it is true for most other user oximeters that have an alarm. Wearing a pulse oximeter for 3 nights proves nothing about the efficacy of the alarm system, but what the doctor says about the oximeter results sure indicates something is going wrong somewhere.

Desat is not the ONLY danger related to apneas. For true "safety", you must minimize the apneas themselves...and not only be concerned with the desaturation they cause.
I will be looking into this, as I trust Link-C not to be a spoiler. More details of how apneas that do not cause desaturation are harmful would be helpful, given that up to 5 per hour in normal people, possibly causing desaturation, are not considered harmful by the medical profession.

Mars, I think its really an individual thing. For you, sleeping in a sitting position seems to avoid apneas.

I am also taking this post on board, as exploring what is said may give me some insight into why I have such good outcome's with my naps.
So I am thinking about getting back to my Sleep Doctor and checking all this out with him. Looking further at my sleep study report. And I am also thinking of having a nap with the recorder function operating, and the alarm turned off, and also a full nights sleep, without the machine, but with the oximeter recording.
Nobody is more determined than me to put this oximeter stuff to rest. This and the No-Nap device has been like a baptism of fire on this Forum. And both posts were intended to just be one-off information posts for those who were interested.
So using the leads that Link-C and SleepRider have given me, I am going to do some more personal research, get more factual information, make a final post, and then hopefully put all this distraction behind me -
for good!
I will not be posting on this thread again, or about the oximeter protected naps, until I have sorted this out.
cheers
