Oximeter Normal Graph
#1
Hello, I'm a new member here. Getting a sleep study done in the next couple weeks and hoping to get some better sleep because of it!

This question is mainly out of my own curiosity, but I haven't been able to locate a "normal" oximeter reading example to compare mine to. Does anyone know what a normal overnight reading would look like? A doctor hasn't reviewed mine in detail yet, I started tracking it on my own after some research into my symptoms.

Hi shermantank45,

Welcome

What is your average value? Most oximeters will record low spikes (outliers or artifacts) if you move your hand fast or they are bumped so the lowest value recorded may not be accurate. My understanding is anything 95% or above is good and you need to mention to your doctor is it's 89% or less. The 90% to 94% is a gray area.

That's the best that I can offer you. Good luck with your sleep study!

My average for last night was 90.81%, which seems to be on the low end. My lows are in the upper 60's about 4 times and I oscillated between upper 70's - 95 for a good 5 hours out of 8 last night. The upper swings being about 15-30 seconds apart.

Thanks!

If the low is not an artifact, then it is cause for concern.

Huh. justMongo, that was not even my lowest, just lowest last night. I have been down to 53% before. I don't think it's a fluke as there's a definite downward and upward motion: 95-70-87-65-80-59-75-53 and back up stair step like that.

Thanks for the info everyone!

I started tracking stuff because I've been feeling worse the past few months, tired all the time, confused, forgetful and generally not well. I'm only 29 years old, was exposed to some toxic inhalants (unidentified) in Iraq during a deployment with the Army. Came home and couldn't pass a fitness test, they diagnosed me with constrictive bronchiolitis in 2010. Apnea hasn't even been on the radar, despite complaining of waking up feeling like I haven't slept. I went to a civilian doctor and started tracking my oximetry a week ago. I'm really hoping the CPAP helps my overall well being, tired of being tired!

If you have not already done so, I'd alert your doctor to these oximeter readings now. They may be able to expedite your sleep test. Some of those readings are pretty low.

Does that happen when you're awake, say watching TV or reading?

I'll let my doc know tomorrow, had no concept of the severity I guess.

Lowest it's ever been awake was while testing my limits, ran until I couldn't, got to 78%. General TV watching and such it hovers between 93-95% usually. Consistently drops 2 points when I lay down, which is interesting.
