Low testosterone and lousy sleep can exacerbate one another. See this: https://pmc.ncbi.nlm.nih.gov/articles/PMC3955336/ For you,, here's the take-away: "Testosterone deficiency may have a deleterious effect on sleep quality that may be improved with testosterone replacement." I'm betting that you'l...

Many thanks for the information and the link. I think your settings are fine, but you're having a lot of arousals. (You can identify arousal breathing because it is deeper and messier-looking than regular asleep breathing.) With just a little bit of luck, you'll have fewer arousals as you get more u...

Thanks for the additional postings. Could you let us know the answers to these questions: Did your doctor prescribe the VAuto machine? And did he prescribe the settings? If yes to either, do you know why? I think we could make some suggestions about revising your settings, but it'd be good to get an...

Welcome! Keep using the mask and machine during the day or evening to help you get used to it. You don't have to try sleeping with it right away. Did your doctor prescribe the VAuto machine? And did he prescribe the settings? If yes to either, do you know why? I think we could make some suggestions ...

It'd be great if you could use Oscar. I'm reluctant to suggest changes to your settings without more data. Your AHI isn't horrible, but with PAP treatment a good goal is below 2, and a very good goal is below 1. Then again, if you're sleeping soundly and feeling rested during the day, I'd say you're...

Welcome! It sounds to me as though your sleep test did not have an adequate number of channels. More here: https://www.acc.org/latest-in-cardiology/articles/2014/07/18/15/42/home-sleep-testing Did you get a copy of the sleep study report? If so, could you post a scan of it? You might want to blank o...

Definitely keep the appointment with the pulmonologist/sleep doctor. Think ahead of time what information you want to provide and what questions you want to ask. I don't have an oximeter, so I can't really help you with that. I looked at the manual for yours, and one question is whether yours can do...

Higher CPAP pressures can induce CAs in some people. CPAP pressure can lead you to blow off more CO2 than you'd normally do when you exhale. With less CO2 in your blood, there can be a delay in the "breathe-now" neuro-chemical signalling that controls your breathing during sleep. Sometimes this will...

What a remarkable improvement! I'm very glad to see it. With EPR off, your flow limitations have increased, but in your place I'd continue for now to do without EPR. I hope someone with expertise will give you advice based on the zoomed-in snippet. You're having some periodic breathing, which isn't ...

Lindsay, your doctor's response is not acceptable. Your AHI should be under 5, ditto your CA index. And the pattern of your CA clusters is suggestive of Cheyne-Stokes breathing, which absolutely requires investigation. Your doctor's insistence on looking at a 90-day average, rather than a recent tre...

A few observations: You go to bed at around 1 a.m. most nights, it seems, but your sleep schedule is pretty irregular aside from that. I'm especially curious to know why there are so many breaks in therapy, some of them quite long. What's going on there? Maybe the colitis? Or something else? I also ...

OK, good; that's what I thought. But when the OP starts inhalation, there isn't smooth acceleration at the outset; instead there's a pointy bump or lump. Maybe it doesn't have any significance, but I thought it was a bit unusual. I've pasted in the screenshot again so you can take a look. Screenshot...

...the bumps or lumps in the inhalation trace. That's actually part of the expiratory limb, so IMO probably cardioballistic artifact. I'd love to learn why the "bump" in the first part of inhalation is part of the "expiratory limb." Probably I don't know what "limb" means here. I googled the term b...

Nocibur, thanks for swinging by. I'd love to get your thoughts about the bumps or lumps in the inhalation trace. (See screenshot.) These seem pretty frequent in semblables's graphs.

I'm still hoping an expert will be able to help you. About the leaks -- you might check to make sure that you don't have any little holes in your hoses and that the hose attachment to your machine is secure. Do you take any medications? Any special stress and strain going on in your life? Is your sl...
