P.S. Also, this guy on YouTube seems quite smart and talks about HRV in relation to sleep and the Oura Ring: https://www.youtube.com/watch?v=AK47cav1i28 But I agree we don't have to talk more about Heart Rate Variability in this thread if it's too off-topic. (Oh, I also wanted to add that when I'm ...

I read your citation from Harvard, and while interesting, it seems replete with "may", "might" "possible-type terms that doesn't instill confidence in the assertions. That Harvard piece, written 6 months ago, makes it plain that researchers are just "exploring" HRV. The Oura citation seems to ampli...

So, it is probably useful to know for sure the details on how Wellu calculates pulse rates and the interval used for each data point. ( my suspicion is 4 seconds - but that actually seems like overkill) Is the following helpful, by any chance? I just Googled: wellue o2 measures pulse every how ofte...

Question on pulse rate reported by O2 ring. [...] I see that during the every night, especially for the first couple hours, my pulse rate changes a lot (as shown in the OSCAR report). Is this a normal thing Hi Ropo. Thanks for posting this question! I, too, wear a Wellue 02 ring every night and I'v...

I think you're right. I think I just don't understand it because it's not an ability I have--yet. I hope one day I will acquire it. You're lucky to have it. Thanks again!

But I guess I don't understand how you could use this feature (ability) while asleep if you are hoping to benefit from the pressurized air, because you need to let that air in through your nose and into your lungs. Big difference between what we can do while awake and have it transition to have it ...

I even breathed through my mouth using my lungs and mouth to move air and NO PRESSURIZED air entered my mouth from the airway that was getting air via the nasal mask....and no air came out that was under pressure.. It was like the mask and machine wasn't on...but they were indeed on. I can do this ...

forum friend dog slobber has taken my image and stuck it on bodies of others, making his own "memes". let's see if i can get him in here to post a few. https://www.cpaptalk.com/viewtopic.php?f=1&t=178094 :lol: :lol: :lol: Pretty sure I haven’t laughed this hard or this long in weeks. Dog Slobber, y...

i wouldn't trust him if'n i were you. doesn't know what he's talking about, most of the time! :lol: :lol: :lol: Oh, I had no idea this was a photo of you! I thought you were posting this photo of someone else or maybe of jimbud. That's why I didn't join in on the teasing. But now that I know, then ...

I can open my mouth and stick out my tongue and blow raspberries at you and the tongue certainly isn't stuck in the backwards blocking the airway position and zero air enters my mouth. I don't do anything with my tongue at all to keep the back door closed because it's not tongue related. I can talk...

and you wouldn't have to feel like the wife if trying to strangle you. :lol: :lol: I'm a woman, so that would be my husband trying to strangle me. I chose the name Chris because I assumed that was gender-neutral but my husband informed me too late that usually a woman is spelled Kris (I'm half-Fren...

I am having a hard time figuring out how the tightness of a cervical collar has anything to do with chipmunk cheeks happening. Pugsy, I feel exactly the same way. I don't understand it either. In fact, last night I was pacing around my living room wondering how in the world the tightness of the cer...

you mean, THIS guy? i wouldn't trust him if'n i were you. doesn't know what he's talking about, most of the time! :lol: :lol: :lol: i think you may have the wrong sized collar. i snap it closed but it's not so tight as to choke me. also, are you using the scunci hairbands, too? Yes, this was the ph...

Overtime, chipmunk cheeks began to resolve itself, pressure was causing my throat to croak, and over time that went away, I was introduced to arophagia,. I prefer chipmunk cheeks over arophagia. Architect, very sorry to hear you developed arophagia. I agree it sounds much worse than chipmunk cheeks...
