What do you think causes artifacts to occur more often at sleep onset in the beginning of the night? Don't know but I would suspect simply moving around more at the beginning of the night and when transitioning to sleep. You are asking questions that we can't answer. Sorry but if you really think t...

Any idea what is causing the sleep onset 70s? My first thought is loss of contact artifact if it looks like the other ones above. last night at the first sleep onset my SPO2 dropped to 74 - it would have stayed there had my alarm not gone off and woken me up. Incorrect assumption that waking causin...

Your time below 90% for the 10 hours is 0.9%, which is 5 minutes over 10 hours. It is not significant. But you clearly do not believe me, so let your Dr figure it out and refer you to a good specialist for health anxiety. You are probably right. That being said, last night at the first sleep onset ...

Did you really sleep for 16 hours?

No - sleepyhead has a weird habit of dilating the times on the data. The starting times will always be correct but for some reason the end times are way later than when I actually wake up,

Ah, okay - here is the CMS50 software data - it is helpful in showing how long each event is and percentage time spent in each saturation range.

Your SPO2s that drop into the 70s are brief spikes, known as artifacts, that are not accurate or true readings. You are being more than a little paranoid about this. In fact, I don't see much that convinces me that your actual SPO2 ever drops below 90. They are all artifactual spiking. I base this ...

Your low numbers are "spikes" from the sensor moving around on your finger. There is nothing that I see in your SPO2 levels to be concerned about

Thanks. You don't think the SPO2 in the 70's is something to be worried about? I thought anything below 90% was bad?

I am not on CPAP as I am waiting to do my in-clinic sleep test. I have told my doctor about symptoms of suspected central sleep apnea and he is very curious/open to exploring this diagnosis. I am scheduled to hopefully get the treatment I need but in the meantime, I am a bit worried about my SPO2 da...
