Intermittent desaturations during sleep

[Geer1]

Try higher pressure (either by increasing in CPAP mode or changing to APAP mode and letting machine increase pressure as it feels fit) and see if it improves your average SPO2 and ODI values. APAP mode could help by increasing pressure only at times when you need it.

OK here is the snippet from the Viatom Wiki:
[quote]
The downloaded session files will be stored in /Users/YourUserNameHere/Library/Containers/com.viatom.O2PCViewer-BLE/Data/Library/Application Support/O2_Insight_Pro/DATA/SerlalNumber.

The "Library" folder is hidden by default, but you can still reach it by pressing cmd-shift-G and entering "~/Library" in the file selection dialog.

This is from a member that had the same problem.  He added this after using the steps above:

You have to go to the menu all the way too left of the screen “Apple icon, File, View, Data, Help.

Select Data select Import Viatom Data it brings you right to the folder with the serial number that is on the back of your device, hit open.

Since I'm not a Mac-ie, the above is Greek to me.  

Upon clicking on the Oximetry Import Wizard (icon on right side of OSCAR), it states:

"OSCAR is currently compatible with Contec CMS50D+, CMS50E, CMS50F and CMS50I serial oximeters. (Note: Direct importing from bluetooth models is probably not possible yet)"

I am therefore confused because it allows Viatom data to be imported to OSCAR here:

Couple more questions:

Is this all the data VIATOM reports to OSCAR?

Why doesn't the data above correlate with anything reported on the 02 Insight Pro report?

[Crimson Nape]

OSCAR reads everything that is in the Wellue/Viatom data file. Besides the statistical data that you listed, it provides graphs in the Daily and Overview screens and provides an output on the Statistics page. To make it easier, what are you wanting that isn't there?

Re-reviewing my oximeter readings. Does anyone know what a normal 02 score is? I seem to get over 9% on most nights.

Dude, you are over emphasizing on your O2 saturation. You need tol relax. As most people here have already told you, general spikes on O2 saturation are meaningless. Your O2 saturation seems well withing the normal average as your device is indicating (averaging between 94 to 97% ) and its pretty good and "normal".
There, happy?:-)
No one is 100% average. Maybe only the lord himself, depending on how many Budweisers he has had:-)

Re-reviewing my oximeter readings. Does anyone know what a normal 02 score is? I seem to get over 9% on most nights.

The maximum O2 Score that O2 Insight will report is 10.0. Before I was using the CPAP mine was literally 0 most nights. Now with the CPAP I'm above 8.0 all the time, good nights are above 9.0. I don't know what "normal" is but all the other data I get from OSCAR tells me the CPAP is mostly working for me. Note that O2 Score is some synthetic measure that Viatom made up. I've never been able to find a precise definition, all they say is "O2 Score is a measure of oxygen shortage during whole sleep. It combines frequency, duration,and depth of oxygen drops." It's helpful comparing the score from one night to the next but I wouldn't get hung up on what it means by itself.

It's worth understanding the underlying numbers. The graph of oxygenation (SpO2) is the primary measurement; normal health people are well above 90% the whole time they're asleep and don't have major drops. Also the "ODI 4%" number, which is the number of times per hour your SpO2 drops more than 4% in a short period of time. Ie: desaturation events. ODI 4% is a measure of your blood oxygenation similar to how AHI is a measure of the interruptions to your breathing. (ODI 3% is the same thing, just with 3% drops instead of 4. The medical literature differs on which measure they use so the software reports both.)

[MCS2014]

Noticing a pattern in that the majority of my drops occur within the first hour of sleep. Any significance to this?

[SarcasticDave94]

Some kind of malfunction in wake to sleep handoff or lots of SWJ/sleep wake junk?

[Stephenie.welch]

Hey MCS did you ever get to the bottom of why your oxygen drops with cpap? I’m going through the same thing

Sorry for the delay, just saw this now. No, still a mystery.
