Hi, newbie here.

Hi,
I've suspected for a while I might have mild apnea just through waking up snorting when lying on my back and the fatigue I get. I also snore really badly. I'm not overweight in fact I'm thin.
I bought a CMS50D+ just to see if it showed anything up. The first night I've posted below as I'm unsure of what it is saying. My heart rate is all over the place when I sleep as well.

Welcome to the forum!!! We are glad you joined us!!! Welcome

Not sure what is going on with your graph but there is definitely something on in the 4 - 4:30am timeframe.

Keep in mind we are not doctors here nor do we provide medical advice. In addition, I did not stay at a Holiday Inn Express last night. Laugh-a-lot

If that were my chart, I would definitely check with a medical professional. Sleep-well

Hey Eclipse.
Welcome

Looks like something bad happening @ 4:23am there.
A really big desaturation event accompanied by pulse rate going up. quite dramatic.
That would be your body going into the "wake up fool! You forgot to breathe again!!"
Possible signature of some kind of really-not-good apnea event.
Not a Dr. here but looks like danger signs to me.
I was getting those too.
Get checked out by pulmonary doc or at least PCP and make best possible speed.

Good luck!

You have zoomed into that one event so that its details are quite clear. As Shastzi has indicated, this is pretty clearly an apnea event. You stop breathing (one assumes), your blood oxygen drops, your heart rate increases as a result, and then you obviously start breathing again and the levels return to normal.

Your blood oxygen level appears to be quite good, except during that event. Your sleeping heart rate seems to be a reasonably consistent ~70-75. I'm not sure what you mean when you say "all over the place".

If this is the only event in your entire evening of sleep, you have an AHI of less than 5 (actually less than 1), which is in the normal range. On the other hand, if you are having these constantly through your sleep period, you should figure out a rough hourly average for the events. A value of 5-15 per hour is classified as "mild", a value of 15-30 is classified as "moderate", and a value of 30+ events per hour is classified as "severe". If it's moderate and especially if it's severe, get thee to a sleep doctor immediately.

Could it be an arrhythmia or a palpitation? Interesting that the change in heart rate seems to lead the dip in oxygen, not the other way around. That could be a sensor / measurement issue, too.

Is it common in apnea events that oxygen levels can dip and recover by over 15 percentage points in just a matter of seconds?


Echo what others said; see a doctor.

That depends on where you place the start of the change in heart rate. That initial ramp-up also fits within the range of fluctuations seen elsewhere. To my mind, the telling point is that the recovery in SpO2 clearly leads the recovery of heart rate. It also doesn't look like a sensor glitch, since the SpO2 and heart rate readings both react, and they both react with a phase difference (time lag). A sensor glitch would have both readings reacting at exactly the same time.

I do agree that the SpO2 drop was surprisingly instantaneous. However, if you zoom into the screen shot, you will see that both graphs in the short period before the drop appear in a different colour. I wonder if there was a sensor glitch, possibly an arrhythmia, at the start of the event which put the graphs into "repeat last reading" mode.
