Pulse/Ox 50F - Questions on the number of events!

Thanks to help from responses to a thread I started last night, I had a successful first night recording. But I need some guidance on the events.

My numbers look fairly good to me:

PR: min. 51; median 64; 95% 72
SpO2: min 88 (0.1%); median 94; 95% 97

But there are tons of events.

Pulse Change 110 events
SpO2 162 events

The default criteria in SH is set to flag these with a rapid change for at least 8 seconds of at least 3% in SpO2 and at least 5 bpm for pulse. The actual numbers are good, but there are so many actual events. I was awake for the last hour this morning with everything still hook up and recording (trying to go back to sleep but couldn't.) And I got up once in the middle of the night. But even if you take those out, there are still a lot. I can't imagine this is normal?

Oh, is the number in parenthesis supposed to be the duration of an event in SH:

#012: 03:35:23 (3)

If so, why is it flagging, for instance, this one when for pulse change when it's set to flag when it's a rapid change of at least 5 bpm?

Thanks!

Are they obstructives? Hypopneas? Clear airways?

Julie, none of the above. AHI = 0. FL, RERA, and snoring, plus all the events from the pulse/ox.

EDIT: These are events produced from the pulse/ox once uploaded to SH.

if you are concerned i would do several nights to get a true picture
then discuss it with yuor doctor

I'm definitely doing this for more than one night. For this one night anyway, it doesn't appear the PR or O2 are issues, which is great. Just wondering if the number of events for O2 and PR changes are a sleep disturbance in and of themselves. Always feel horrible. I know bad sleep can have a lot of causes, so I have a list of things I'm checking on.

Heart rhythm irregularities are common during sleep. Sometimes their variability tends to get in the way of evaluating what is actually going on.

One thing to pay attention to is the %artificts recorded. This tells you how many times the signal was lost and things had to work at getting reconnected.

Numbers are a starting place but sometimes a graph shows more. Is there anyway you can post a graph?

From SH or the SpO2 Assistant?

The events I mentioned are from SH. SpO2 Assistant events are lower even after I adjusted the parameters to the same as SH. Probably just a different in each calculates things. Which begs another question: Which event counts are more reliable, SH or Assistant?

Does SH have an artifact percentage somewhere? I see it in Assistant.

I am used to Assistant.

Part a graph of about an hour in the middle of the night. http://imgur.com/1ncHUID

Not sure how to get the whole night in one image across the screen, if that's even possible, or even more than just about an hour. First time using it today.

And the events listed on the report at the above image are less than the ones I originally mentioned because those were from SH.

Your data doesn't look that bad.

Deeper sleep stages look something line what you see in the 3:15 to about the 3:35 range. Usually there are several of these stages each night. If you only have one you may be missing out on deeper restorative sleep.

Your artificats are not significant so you are tolerating the device well.

Your oxygen levels seem reasonable.

The next step is to collect a few more nights of data and see what changes. If everything stays about the same you can rest assured that your oxygen levels are adequate to maintain quality life while you sleep.

There are a couple more in the graph that look something like the 3:15 to 3:35 range, but not as pronounced.

Yep, it's all charged and ready to go again tonight.

Thanks, HoseCrusher!

Would anyone say that these two major drops/spikes right before a break in contact are to be ignored? Heart rate for that straight spike both times was 150 and both times at the exact same time a straight drop to 64 on O2, then immediately a break in contact.

Looks like artifacts to me. Ignore them.

My thoughts, too, but being a novice at this, just need a little feedback. Thanks, HoseCrusher!
