Tweak with pressure settings?

[andy2016]

Not to be overly picky, I have managed to get my AHI to about 1.7 on a regular basis. My avg. pressure is little over 12 and my min. is 10. I want to get my AHI to below 1, should I increase the pressure to an 11? Could it make a difference?

Thanks!!

Are you concerned about the number or how you are sleeping and feeling? If you are sleeping well, you could increase the min pressure...it might make a slight difference. Your pressure is also hitting max 17 for a short period...you might increase that to 18. Personally, I would be inclined to leave it alone since you are so new to all this. Numbers do not stay constant AHI can vary from night to night.

No, not so much the number but rather the quality of sleep. The less hypopneas, the better the sleep I am assuming.

If I were you, I'd suspect the pressure changes. I'd suggest narrowing your pressure range to 10 - 13 cm. for awhile. Or, even at some point trying a straight pressure within that range and then tweak from there.
Not all events are worth chasing and sleep quality is of primary importance (along with eliminating as many events as possible). It can be a balancing act, but it's doable.

generally yes, the less events, the less sleep disturbances. as lsat said, it's a balancing act, more pressure will make for less events but at some point, the pressure may bother you, or the side effects.

feel free to try what wulfman... suggests, he's a big proponent of single pressure, and often repeats his idea that the gradual pressure changes the apaps make disturb sleep.

I think his suggested pressures are too low for you though. but, feel free to try it for yourself... give it a few days, and try what LSAT said, and give that a few days, sleep varies from night to night, contingent upon many conditions.

Perhaps bump my min. to 11 and see if that does anything? Can increasing min. affect how high the max pressure goes throughout the night?

yes, interestingly though, raising min to where it needs to be sometimes causes the max reached to be lower, since the machine prevents more things happening in the first place, and is able to reach needed pressures for exceptions faster.

Maybe.......maybe not. It depends on the person's breathing characteristics........Flow Limitations, Snores, Hypopneas, Apneas......can all affect what the pressure will do if you're using ranges. If increased minimum pressure alleviates some of those, then there is less chance that the pressure will climb higher. If it doesn't, then it will regardless. No "concrete" answers.

Makes total sense. Hope that's the case.

I did the straight CPAP pressure with great results. (thanks to wulfman) I find sleep quality better with limited pressure changes.
Hope you can get your AHI below 1.
