Another new AirSense user with a couple questions

RE: Another new AirSense user with a couple questions
You get centrals using pap when your CO2 drops and your body Pauses to let it build up. Cpap with EPR does a better job of getting rid of the CO2. When your body gets use to the therapy it will breathe with less CO2 and the centrals will go down. Then you can add the EPR back

RE: Another new AirSense user with a couple questions
CO2 provides our main drive to breathe, the need to remove CO2 from the system and lower blood acid levels. It is NOT to breathe in O2. Needing O2 can cause you to breathe faster, but it will not cause you to initiate a breathe.

ANY CPAP/APAP/BiLevel will improve the mechanics of your breathing, this includes flushing CO2 out of the system, As the CO2 approaches your apneic threshold your breathing volume gradually becomes less until it passes it and you stop breathing (Central Apnea, one cause, a common one with PAP therapy). Having stopped breathing CO2 levels build and you gradually take deeper and deeper breaths resulting in the typical pattern of waxing and waning breaths with central apneas frequently at the nadirs.

I turned off the EPR last night. AHI 1.8 this morning.

I've seen those numbers before with EPR on, and then 4.x the next day. I'll leave things alone for a week or so and see what happens.

I haven't looked at details this morning though, so I don't know how many were CA vs obstructive.

OK - it's been a week or so since I turned off the EPR.

Since then my AHI numbers have been <= 1.8. I've seen a few < 1.0, and most seem to hover around 1.2.

I have not downloaded the details into Oscar, so I don't know if that EPR change took out the CA events, but something definitely changed.

I did order a ResMed F30 full face cushion/mask. I'm looking forward to seeing how that works for me. I've lost a lot of weight in the last 6 months, and I now have a problem with air pressure pushing out of my mouth even though I sleep with my mouth closed. This wasn't a problem until that weight loss, so I'm going to switch from nasal to nasal/mouth and see what happens.
