RE: Massive AHI increases after septoplasty? - Sleeprider - 02-20-2024
Well you did better with a lower range and lower pressure. Go review your previous thread and get back to what you were doing before, and we can go from there. Also, don't include the big calendar on your graphs, we can't see the settings and respiratory data.

Alright. The biggest reason i was told for the pressure increase was my oxygen as i was desating more at 3-8, into apparently close to 89-87. So unsure. I will go back and also include my o2 stats during the night.
RE: Massive AHI increases after septoplasty? - Dread - 02-20-2024
I think I agree with merging threads. Sorry, should of added this to previous one. I had a question. Are the UAs I’m seeing mouth breathing or PA or both? Like are they just positional?
RE: Bilevel ASV - Resuming After Septoplaasty - Sleeprider - 02-20-2024
I'd like to get back to settings like where we left off. If you have oximeter data, let me know what we're dealing with or include it in charts if possible. Elementary ventilation mechanics, we use EPAP min which acts like positive end expiratory pressure (PEEP) for oxygenation, and pressure support for ventilation. Your doctor's advise and explanation seems to be inconsistent with that established approach.

Okay. So PS MIN MAX 3-8? What would EPAP Min and Max be?
RE: Bilevel ASV - Resuming After Septoplaasty - Sleeprider - 02-20-2024
Let's start with 3 min and 8 max and go from there.

Kinda sounds like a case of over-treatment with ASV for treatment emergent CA. Nice. What Sleeprider has said about those prior settings is on the right track from what's shown.
BTW you're going to be hard pressed to treat flow limits on the ASV. It's not going to play well chasing those, the CA algorithm doesn't care about the FL. It's job is eliminate CA.

My confusion is why is it much worse after nasal surgery? Before the surgery I had insane nasal resistance, pressure wouldn’t go up my nose at all, that’s why I was told it was increased along with with more range to let the ASV do it’s job and stop o2 debating. It was alright before, but now it’s like the pressure is either causing more apneas or less resistance

You said the procedure was on the 15th? Like 6 days ago? Your nose just got sliced up, be a little more patient. Most of the time they do more than just the septum because the other internal structures in the nose adjust to the wonky shape and need to be tweaked all at the same time. I had a three-in-one done on the 12th of January and I'm only just starting to feel like it's really settling in after six weeks. You probably have some post-op inflammation that's affecting your results.

Hi SleepRider. I've been slowly implementing the drop from 3-8. Im slowly adjust the pressure down over the span of a few days. I was wondering if you mind taking look at this. AHI was pretty good last night but still feel tired. Got the leak down. Im wondering if these are arousals from leak, flow limitation or both and how to treat them?
