AHI meaning on M series LCD screen

[ddpelp]

Question on the meaning of the AHI screen on the LCD of my Respironics M series auto CPAP. When it shows AHI = 3.3 does that mean I had 3.3 or the machine reacted to 3.3 or I just had 3.3 that were NOT treated with increased pressure? Thanks I know this is an average and have read the LCD info is not very accurate but would like to know what it is trying to say thanks

It means that you had 3.3 averaged during the night.

Could be both hyponeas and apneas.

I would assume the machine reacts to all it sees.

If not corrected it would show up as NR on the data. ( Non responsive)

I was not sure. I had hoped it meant that the machine reacted to apneas. I am guessing the 3.3 is average during the full session?

I am testing two mask sizes from my doctor a medium and a large please read this question as I have updated that info a little thanks

I am trying to understand what I just read in these posts. Lower AHI's are good but if the machine responds to all of them, and does not say non-Responsive isn't the problem being treated?

Will a higher AHI number mean that you feel worse that day or not?

I have not gotten lower than 8.8 and had 20 last night on an M-Series. I don't want to worry about things that are being treated.

Hi All,

If I have a straight CPAP machine (which it happens I do), how would "the machine react" - how can it correct when it is at a set pressure? On an APAP I can understand this, as the machine can vary its pressure when needed.

Bottom line - I figure that with my straight CPAP, the AHI I see on the software are the "ones that got away", true apneas ("A") and almost apneas ("H") or hypopneas. And there would be no such thing as a NR on a straight CPAP.

Is this accurate?

It is very confusing - on an APAP, if the event registers as an Apnea or a Hypopnea - isn't that a NR??

Help out there!

thanks...
