Severe mixed apnea at the age of 35

It can, but usually only in phasic REM, and as I'm sure you've noted, usually not like this.

But it do look like more than a coincidence!

The arousals numbers in the NPSG don't seem to add up. It claims a lot of respiratory arousals, but there doesn't seem to be enough respiratory events. At any rate, big arousal numbers.

Does long-haul Covid create respiratory instability? Certainly a good thought.

Yo Herb, did you say you have oximetry data?

actually when i did some research on covid and possible links to newly established apnoe i read in one or two early studies, that covid has been observed to affect respiratory stability. somehow it can affect brain stem or the chemo receptors.

and yes I have oxymetry data. unfortunately I was not yet able to import it to Oscar or sleephq. it was possible in the past, but somehow they changed the app, so the export data is not compatible anymore. I could share it as csv, but it would be really a lot of work just scrolling through the timestamps in excel format. what exactly do you suspect to see? any specific timing on which date? the i can check

How about some DWing? CPAP 5.0 cmH2O and EPR Off.

Virtually all the central apneas occurred on Right Side, and disappeared upon position change.

Obstructive apneas occurred supine.

only in one of the studies. in the last one right side was my best with least apneas, so maybe coincidence?

and where did you spot obstructive events? the hypopneas? can't they also be of central origin? I might have heard sth like that

What means "DWing"? So you suggest to turn pressure down to 5? in the studies 5 seemed to less as i still had hypopneas in it. but this could also be coincidence. epr is off to my knowledge, but I will check once again.

Find any software to run reports. More interested in Heart Rate especially as it relates to periodic breathing.

The Covid/respiratory data suggested the presence of chronic hyperventilation tho, and your Minute Ventilation doesn't really scream that.

Ahhh...our old friend crappy sleep from maybe some spontaneous arousal stuff????
It does beg the question "why the crappy sleep"...which came first the instability or the arousal??

I just looked at my own RR graph....looks absolutely nothing like this guy's above.
Mine is all over the place all night long and every night. I never thought much about it since it's one of those things I really can't do anything about anyway. I have never been into doing much extra work about something when I don't have any way to do anything about it. Waste of my time and very limited energy.

here is the report of the night of 27th last Friday. don't know it this format is of any use or if you can read it. But basically my heart rate is very low at nights. average mostly in the 50's.

DWing is "dial wingin"-- changing parameters with basically NFI what we're doing, or for that matter, expecting.

But in this case see if PB lessens. Hypopneas/apneas could increase, unless they're actually central.

I think you do the reverse experiment (add pressure or EPR 3.0) and get the same information (is it CompSAS/increased chemo responsiveness).

The instability is always there, you just need a disturbance to trigger the cascade. I'll find a couple good ones.

does the heart rate itself relate to PB or only the heart as in suffciency?

Second part: if i get it right my resp rate doenst look like chronic hyperventilation and thus it's unlikely to be covid? Just want to make sure that I can follow ..

Can you change HR scale to 30-90?

The Covid data is very preliminary. I wouldn't be taking anything off the table just yet.

That's what we're gonna find out as soon as you blow it up.

And it probably does (it looks like that in the coarse graph), that's kinda how HRV works.

unfortunately not with the app I have. but you can give me a time and in can zoom in.

Also what's the Covid story. Severity, oxygen, ventilator, etc. Specific lung involvement.
