Event defined in Resmed P10

Post by Plunder » Wed Jan 29, 2025 8:59 pm

Hi, Im a new user of a P10 Resmed.I need an explanation on something.

When I see an event per hour of five, it seems to me that that's telling me that I'm having a sleep apnea event 5 times per hour.

When that event is happening, does the machine force more air through to open up the throat and fix the event?

Therefore, is this just a message of how many times it has to do that? I mean, it registers the event. Does it fix it by increasing its pressure temporarily?

I've always understood it to be the number of times the cpap has to increase its pressure to open up the throat.

Is that it is that what an event is ? And does this cpap then increase the airflow when it detects this event to prevent this event from continuing? Isnt that the main function?

Thank you if someone could clarify the definition and how the cpap does its thing.

G'day Plunder, welcome to the forum.

First, a question for you - what machine are you using (make and model)? P10 is not a machine, it's a type of mask. And what are your settings?

To address your questions, I'll have to assume that you're using an auto-titrating CPAP/APAP machine such as the Resmed Airsense 10/11 Autoset. These machines will typically operate at the lowest pressure in the set range, and will increase pressure in the case of a precursor such as snoring or flow limitation. They will not increase pressure during an apnea, as they can't generate enough pressure to "open the throat". They will wait until the apnea is finished, then increase pressure to head off any further events. After a while, the pressure will drop down again.

To get a better idea of what's happening, use one of the free software apps such as Oscar or SleepHQ - links in my signature. These programs will give you a detailed breath-by-breath chart, so that you can see the precursors, apneas and hypopneas. And you'll be able to see when the pressure changes.
