Help with Interpreting my WatchPAT ONE results

Hello, I recently did a home sleep study with a WatchPAT ONE device through Lofta and was diagnosed with mild sleep apnea (low AHI, RDI = 9.7, and REM RDI = 20.4). CPAP treatment was prescribed but I am unsure about the benefits given my low AHI. What is the significance of the REM RDI? I do usually wake up not feeling well-rested and sometimes experience moderate to severe daytime drowsiness. I am a 20 year old male with a BMI of 21.7. I would appreciate any help with interpreting the results from the test. I have attached the report. Thank you for your help!

I don't think you have anything and need to look elsewhere for your issues.

What, aren't you going to ask why?

I'd love to know why!

Why?

It isn't RDI, it's pRDI- PAT events that with other criteria are used to score respiratory events. Oxygen desaturations are minimal (perhaps not even valid). If there were pulse events, in a 20 year old they would be about 6-10, not 40-50.

See the area where most of the issues are claimed to occur:



That's scored artifact, but that area is probably all artifact. Doubt this was reviewed by a qualified (or even unqualified) individual.

IMO - Train Wreck Sleeper.

OK, I get it that PAT RDI can't be treated like EEG RDI.
But what about the snores during that period?

And I don't understand what numbers you're referring to in the following sentence

Namely: What do you call a "pulse event" and what does the 6-10 vs. 40-50 refer to?

A pulse event would be an increase in heart rate usually >6 BPM. HR increases follow respiratory events (sympathetic/parasympathetic response and now you have some extra blood to move). In practice, they're like 6-10, as seen in the validated WatchPAT report.

The OP HR increases are 50-60! Undoubtedly motion artifact.

Real snores are much tighter, but IMO that whole area is jumping around-- the snores are artifact as well.

Are we to believe the scored REM is real?

Well, maybe some of it...

Thanks, Rubicon!

Thank you for the information! Do you have any ideas as to next steps/ possibilities I might look into if it's not sleep apnea?

Sure!

Start out with a complete physical by a good internal medicine guy (gender-neutral).

If they (gender-neutral) think you have a sleep issue, see a real sleep medicine guy (gender-neutral).
