Strange Night -- Power Went Out w/BiPAP

[FatBruno]

Last night, one of the breakers in my house was tripped and my BiPAP machine lost power briefly. (See data attached below)

I have no idea what caused the breaker to trip. This has never happened before. But I woke up 10-15 minutes after it happened, reset the breaker, the Resmed came back on, and I tried to resume sleeping.

However, I noticed something wasn't quite right after turning the machine back on. Maybe it's all in my head, but it seemed to me the airflow wasn't as strong as it normally is. I had wondered if the clinician settings were reset on the machine, so I checked those. Everything seems to be the same. I'm not sure how to describe it really. The airflow feels like it's passing through a screen, or whatever (fans?) mechanisms are running are not performing as well as they did before. It's just not very strong. At least, I think so.

I tried turning the machine off and on several times; I tried changing the hose because I thought maybe there was a leak in it; I tried raising the EPAP by 1 point just to see if I noticed a difference. Eventually, I just sort of gave up and went back to sleep. You will see in the data below that the machine was being turned off and on several times, so that's why you're seeing those gaps.

Looking over the data this morning, Oscar definitely reports that the machine was working, though around 5:45 there's a cluster of high flow limit (not sure what that even is), a few apneas, and the leak rate seems to spike; but so too does the pressure. It's not unusual for leaks to increase on me during high pressure. I've tried tackling this with an extra strap, different masks, etc. Nothing really works to be honest to eliminate the leaks.

Anyway, the airflow just seems different to me. I am worried maybe the machine was damaged during the power loss, but I have no way of verifying it. I bought the machine only two months ago. I do not notice any other functional issues with it. If I'm reading the data correctly, it is clearly still "working" and even reached max pressure after the power loss.

I realize this is a very specific scenario I'm describing here; but I'm wondering if anyone here might have had this problem (or something like it)?

I tried attaching my Oscar data, but it says "board attachment quota has been reached".

I seriously doubt your machine was damaged with the power outage.
What I think may have happened is you were using the much higher pressures when the outage happened.
Your body and brain was used to those higher pressures but when you restarted the machine and it went back to the normal lower start up pressures the brain was wanting and expecting the higher pressures that it was used to and the brain was rebelling and sending out "something isn't right" signals.

The pressures really weren't any lower than usual but they seemed a lot lower to your brain because the brain was expecting the higher pressures that it had grown accustomed to.

See what happens tonight now that the brain will have to do a normal reset and expect the lower starting pressures as being normal and not abnormal.

If it really bugs you and you are really worrying about pressures being delivered you can get or make a manometer and test the pressure being delivered.

This makes sense. I hope you're right. I'll see what happens tonight. Thanks for the input!
