Hypopneas correlated with flow reduction?

RE: Hypopneas correlated with flow reduction?
Last night's session was the new "normal". 0.52 hrs of hypopnea in 4 events, nothing else remarkable, no leaks, but SPO2 only 90% this morning. Rising concern among my ALS/RT team, with telemedicine appointment (I'm beginning to like those) with neuromuscular pulmonologists scheduled for Tuesday. The oximeter (50F) ran out of juice early on, and the Oximetry Wizard couldn't find any valid data. I'll try again tonight.

An oxygen bleed addition to the the existing machine is a pretty easy modification. We have a wiki on Oxygen Bleed for CPAP if you're interested. I hope you will inquire about the Resmed Aircurve 10 ST-A and iVAPS (intelligible volume assured pressure support). It is a far more sophisticated and comfortable non-invasive ventilator and I'm interested to hear your medical team's feedback on that.

I'll pass their wisdom along. They're talking about mouthpiece ventilation during the day, but no significant changes to the nighttime regimen so far. Tuesday's meeting should be interesting.

RE: Hypopneas correlated with flow reduction?
Finally got everything to work. Good session with oximeter running. Only odd thing was when I first tried to use the Oximetry Wizard, it complained there was no data on the device. I then fired up SPO2 Assistant, which found the data OK. Back to the Wizard, this time it found data, but it complained about the name of the SPO2 device being different. This is my 2nd device, so I'll look into that. Bottom line: same pattern of hypopneas, no dramatic O2 changes. Large gap in data at about 10:42 is when I got back into bed after a potty break, the machine didn't really turn on when I tapped the button. Didn't notice it immediately, but after struggling to breathe for a while I checked it and made sure it was on. That single toggle for on/off has always struck me as bad design. May turn SmartStart back on, as it's a major job for me to get in and out of bed.

FYI:  Ever since SleepyHead, the CMS-50 importer has always complained about a different user name.  It always uses, "User", as the name. This has no bearing on the data, so just ignore it.

Does the Oximetry Wizard need an underlying CPAP dump to operate? I wore my CMS-50 all day today just to see what happens, and I'd like to use the Wizard instead of the SPO2 Assistant to display the data.

RE: Hypopneas correlated with flow reduction?
Nothing too scary about the SpO2. If you look at the respiration rate, it varies a lot, and it does that because your pressure support is fixed. With ST-A and iVaps, your respiration rate would stabilize and the pressure support of the machine would vary. Think about which one would result in better sleep. Pleae self-advocate for the ST-A.

I'll try, but the medical establishment in Seattle is pretty messed up right now, Medicare is getting very fussy and denying all kinds of things, and ROI on my health-related expenses looks pretty dismal.

Last night, something new: a ton of UAs in the early AM. Tried to sleep on my back, which the mask prefers, but my body doesn't seem to tolerate well. Struggled to turn onto my side, then slept OK until the mask started to burp to wake me up a little before 6. Time to get up anyway to watch NASA Live for the SpaceX docking.

RE: Hypopneas correlated with flow reduction?
Last night we had a good pass of the ISS with clear conditions. I watched the ISS climb in the northwestern sky and about 25 seconds after seeing the ISS a second object appeared on the same trajectory, the SpaceX Dragon capsule in pursuit. As we watched, the Dragon entered the Earths umbra while the ISS remained visible, so the spacecraft was still in a lower orbit at 9:50 PM EDT. I figure seeing those two in the sky at the same time ahead of the docking was a once in a lifetime sighting.

I don't suppose you had your oximeter on during last night's events? Looks more obstructive from here.

RE: Hypopneas correlated with flow reduction?
Great sighting. Time to buy a serious telescope.
No, oximeter is such a PIA to use, I only use it once in a while. I wore it all day yesterday, and when I went to stop it, it had already stopped recording. Nevertheless, I got over 10 hours of data, nothing terribly exciting.
The UAs may be related to sleeping position, cervical spine issues, and use of the collar. Probably not worth the time and effort to determine which.
