Good idea. I'll read about obesity hypoventilation syndrome again. If I remember right, it doesn't fit me as a diagnosis: I can breathe well enough to burn as many calories-per-hour as anyone else at the gym, and OHS sounded completely incompatible with that. But it might provide some insight.

What is behind this? What are you really concerned about? Do you feel energetic during the day? Do you have excess sleepiness during the day? Just before bedtime, do you feel tired but not stressed? Reading this forum, one might think the objective is to achieve fine statistics and pretty line grap...

Thank you. I'm not trying to fool it. I'm trying to get it to accurately detect that my airway is open, when my airway is open. And of course, now I was trying to make sure I haven't been fooling myself into thinking my airway is open when it's closed. And no, it was open. I was inhaling, which I co...

FOT?

Having one nostril blocked isn't necessarily a problem, if you can get enough air through the other. My out-of-date browser won't show me your SleepHQ info, and even if it did I'm a newbie at looking at CPAP squiggles. But from what I've heard, if the tops of the squiggles are flat-ish (of outright ...

When I say "hold my breath with my airway open", think of it as breathing in or out very, very slowly until I can't tell which I'm doing from one fraction of a second to the next. The air flow absolutely is stopped only by trying to hold my diaphragm as still as possible. It's been a while (I didn't...

I've only been using CPAP for a few months. Now it's cool-weather time of year here in the northern hemisphere, so I've just encountered condensation in the hose. (Aka rainout -- if that's not the same thing, someone please correct me.) The obvious solution is a heated hose, to keep the temperature ...

I use an ordinary light-blocking mask that I already had, and just have it do what it can. Lots of light gets through, but it's better than nothing.

Thank you. That's what I thought -- as far as it goes. But what kind of flow response is it looking for, and what can cause that? As I said, i tried holding my breath while keeping my airway open, with all the variations I could think of, and none of them got flagged as a "central apnea" by the mach...

When I was getting acquainted with my machine (it's an ibreeze, in case the auto text isn't working), trying it out while awake, I wanted to understand what it was responding to. I could generate as many "obstructive apnea" flags as I wanted, just by pausing for fourteen seconds between breaths. Usu...

Yeah, that was tricky... Thank you. So it looks as though what I need to do is view the image on the image-hosting website, right-click to get "copy image link", and use that in the BBCode instead of the URL that the hosting site gave me. Let's see if it works this time: https://i.ibb.co/rfyHmgHc/1...

You could set user flags in Oscar ... My machine isn't compatible with OSCAR (yeah, in retrospect I probably should have spent the extra money for an OSCAR-compatible machine), but most mornings I've been looking through my flow-rate graph on the software it does use. In a typical night's squiggles...

Let's see if this works ... .



Apparently not.

Maybe this one ...

Or does it work as just a link?

Well, the link works, at least. But how do I post it so it shows up as an image?

I'll second the point that the machine has no idea whether you're awake or asleep: it's a CPAP, not an EEG. All it can do is guess, based on your breathing. Mine is a cheaper one, that doesn't even try. But I'm clueless about CA-flagged events. I can generate an "apnea" with every breath for as long...

What stops you from using it longer? Can you zoom in on the flow rate graph? I have a machine that's incompatible with OSCAR, so all my graphs look different. But it seems to me as though that might be too much leakage. Wearing the mask while you're awake should help you notice whether there's too m...
