I guess I was expecting more red flags and shiny lights on the report.

I did some research on pulse oximetry and it seems that a oxygen desaturation index (ODI) of 5 or more typically correlates with a sleep breathing disorder (SBD).

My wife had a ODI of 1.1
With CPAP I had a ODI of 2.3
Without CPAP I had a ODI of 6.4

I feel relatively comfortable now that I have leared what I need to be able to give this to my SPO7500 to my mom or father-in-law and be able to make some sense of the reprort. As someone said before in another thread, hopefully I dont get picked up for practicing medicine withour a license.

MUSE-INC:

Great info but my CPAP machine did not register a hypoapnea at that time either. So I wonder if something else can cause the DeSat or if the CPAP machine may not have picked up on apnea or hypoapnea.




Treehorn,

One other little tidbit ...

You just posted the ODI (O2 Desaturation Index) for with and without CPAP.

Those that read the oximetry reports view the ODI as the equivalent of reading the AHI in a CPAP report.

The numbers correlate, so that the ODI can be interpreted as the AHI.

Check the two numbers ... you should find them the same or very close.

Some of your 'desats' could actually be movement artifacts and not true desats at all.
