Been using CPAP for years. Finally got Compliant about 3 or 4 years ago.
My question is when I read the data in Res Scan, are the number of Obstructive Apneas and Hypopneas the number per hour it saw and prevented? Or are these events occurring with the therapy?
For instance, Apnea Index: 4.4, Hypopnea Index 1.0, and Central 4.1 with and AHI of 5.4.
Is this how I am doing because of the CPAP or is this what it saw and corrected?
Do you get where I am going with this?
The AHI is the number per hour of events that occurred WITH treatment. It tells you how you are doing under CPAP therapy.
I don't think there is any simple way to be sure of what apnea events it actually prevented (how do you measure what isn't there?), except that likely many of the hypopnea events would have been apneas but for the machine.
If you know what your sleep study showed, then subtracting your AHI when on the machine from your AHI when off it in the sleep study should give you a rough idea, but the night of the sleep study is only a sample of one and it's dodgy to compute statistics from one sample.
The above is my opinion. It is just possible that I may, occasionally, be mistaken.
I am neither a Doctor, nor any other kind of medical professional.
Everything put together sooner or later falls apart.
Your brain is not the boss.
WELCOME! to the forum.!
Hang in there for more help with interpreting ResScan.
Much success to you as you continue your CPAP therapy.
