[Diagnosis] Interpreting Data on Res Scan
#1
Res med S9 Autoset. In Auto, Min 7CM, Max 20.
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.

G'day bstill57, welcome to Apnea Board. As Ed said, the results are what the machine is report with therapy. I see that all your apneas are central with no obstructives. Have a look at the pressure graphs and see if there is a correlation between the apneas and high pressure. With your upper limit set to 20 it's quite possible the pressure is causing the apnea

You might want to bring the maximum pressure down to say 15 and see if that makes a difference. (As always, only make changes once a week or longer - you're looking for a long term trend, not a one night special).
