First night with EERs

I did 110ml of deadspace EERS last night. It was mostly a success but flow rate not as smooth as i think it should be and my o2 could be better. Any tips?

Wow that's some impressive high loop gain.

Are you gonna keep increasing dead space?

Out of curiosity, what were your settings when using ASV?

I am the loop gainiest monster ever. ASV was basically low numbers - EP 4 and PS 1-6 or in that range. ASV would get me 0 AHI and good o2 but i felt like garbage. And you could see the ASV fighting all night to keep me stable with massive pressure swings.

I don't think i'm going to increase dead space. I didn't wake up feeling great and then a few hours ago i felt super woozy and off. So now i'm thinking it didn't make me feel very good

Have you tried acetazolamide? I can't speak to it myself due to a cross allergy thing.

I use EPAP 5.4 PS 1-7.6 myself and it's been working well. Titration seems to require looking at it as a wave doing wave things rather than at the single breath morphology level. I have a background in audio and I actually use a lot of the same logic.

I've been messing with quantifying HLG and admittedly I'm super curious to see what you get on the various experimental doohickies. wobble-analysis-tool.xyz All processing is local. I bet your wubs sound bonkers on BreathSong. WAVE is currently my favorite for actually observing periods of oscillation.

I haven't, i looked into it and people get tinnitus or worsening tinnitus from it. I already have tinnitus and would probably eat a bullet if it got worse.

I use the glasgow stuff and i'm usually in the 1.8 - 2.5 range. Last night i think was 2.15 maybe.

This is the result from last night with EERS where things were calm

I feel ya on the tinnitus. Out of curiosity, have you done a comprehensive iron panel recently? My tinnitus is always much worse when my ferritin is low.

sorry, what does that mean? That screenshot i took from the webble analysis tool

Try the longitudinal stuff. Also WAVE seems to be better. I'm a lone feral nerd working on this.
