AHI comparison to home sleep study results
AHI comparison to home sleep study results
I am interested in comparing the AHI reported by the Resmed Airsense device and the report of my home sleep study that initiated CPAP therapy.
The Airsense 11 is set up for APAP with an initial ramp of 4 cm for 30 minutes, max pressure of 15.
So the home study (reported by the doctor was 68 hypopneic events, 10 apneic events (1 central) over a 7 hour 14 minutes recording period.
The doctor reports a respiratory Index of 11.
So my question is: Can I compare my home sleep study results with my experience on apap.
MyAir app is telling me that my AHI is (on average) 3.5 over the past week. Is that an improvement over the sleep study (which did NOT involve any sort of pap) ?

Re: AHI comparison to home sleep study results
Are you asking if an AHI of 3.5 is an improvement over an AHI of 11?
Re: AHI comparison to home sleep study results
No, I’m asking if a “respiratory index” is exactly the same as “AHI”. And if they are somehow different, how does one compare to the other.

Re: AHI comparison to home sleep study results
"Respiratory Index" isn't a common term. Perhaps it was "RDI" for Respiratory Disturbance Index?
However, no, and RDI isn't the same as an AHI, AHI is how many apneas or hypopneas you had, on average, per hour. And RDI is how many times breathing issues disturbed your sleep per hour, which is usually higher than the AHI.
Get OSCAR

AHI - https://www.cpaptalk.com/wiki/index.php ... pnea_Index
RI (Respiratory Index) is a bit informal.
RI (Respiratory Index) is a bit informal.
If you add the apneas and hypopneas and divide by 7 hours 14 minutes, you get 11 which is what this doctor is reporting. So, it seems she is referring to AHI as RI.
Re: AHI comparison to home sleep study results
Are you sure Respiratory Index???
Is it maybe RI and someone assumed Respiratory Index??
ResMed's ApneaLink home sleep study reports do use RI term but it is Risk Indicator.
see what I said here

Re: AHI comparison to home sleep study results
Quoting from the Drs written report: “An Apnealink air monitoring device was used for the study.”
SUMMARY:
“RESPIRATORY EVENT INDEX: The respiratory event index is 11.”
“IMPRESSION:
1. Mild obstructive sleep apnea
2. Mild nocturnal hypoxia
3. Mild snoring”

Ahhhh.

Re: AHI comparison to home sleep study results
If you do the math on the numbers he quoted, RI is equal to AHI. This would mean either they mean AHI by RI, or he had no RERAs during the study. He had a HST which doesn't score RERAs.Pugsy wrote: ↑Mon Oct 18, 2021 8:11 pmAhhhh.

But as a practical matter, it seems reasonable to say he is getting significant benefit from CPAP. Also, using OSCAR to optimize his therapy may result in even greater benefit.
