Can pressure be too high?

[NRA_Bear]

For the past several weeks I have had A.I.s of less than 1 (typically 0.0 - 0.1) and A.H.I.s of less than 5. I have lost 25lbs. since I had my split-night study and am wondering if I should consider lowering my pressure? Can having a pressure that is too high reduce the effectiveness of CPAP, or is it more of a comfort issue? I've noticed that I'm starting to feel a little more tired lately then when I first started treatment back in March. Just curious what y'alls take is on it.

Thanks,
Bear

My doc tells me that if its too high you introduce the risk of central apneas

I think it can be higher than needed. It doesn't hurt to tinker with it. If it is to low, your gonna know. But I think too low is bad. so drop it a point at a time and see how you feel.

I agree with your thinking. Have been in a situation where the lab told me to set my machine to 15 CMs but the lab tech had messed up & transcribed what should have been 13 into a 15 - so for about 14 months I was on too high a pressure.

At 1st I felt a bit 'super charged' but spent an awful lot of time grappling with mask management issues + aerophagia.

After experimenting on my own I settled on Bilevel set at epap 10 & ipap 13 - then 2 years after the 1st study did a 2nd (plus had lost a lot of weight) & guess what ! - they titrated me at 13 CMs. They did say that 12 CMs would be okay if I preferred it. But 13 seems to work fine.

I don't really believe there is too much harm in having a bit more than is needed (as in the case just explained) but it is he side issues of having more pressure than you need that are likely to be a problem.

Also the comment posted above that too much pressure may trigger centrals is generally borne out for some people who developed what is called CompSA (Complex Sleep Apnea). CompSA is where someone starts off with OSA & then when on cpap therapy begin exhibiting a measurable amount of CAs (centrals). The CAs go away when the cpap therapy is dropped.

MixedSA is when someone always did have both OSA and CA (Obstructive Apneas & Central Apneas).
