Respironics Dreamstation BiPap Suddenly Weak / No Pressure / BiFlex

Respironics Dreamstation BiPap Suddenly Weak / No Pressure / BiFlex
I have a Dreamstation Auto BiPap and my treatment lately has been pretty good, my AHIs have been under 3 until the other night suddenly my machine stopped making pressure.  It seems like BiFlex is suddenly acting differently (is BiFlex supposed to be an adaptive/learning function?).

The night before last I thought I was just having a bad night I was so tired I ended up taking off the mask and passed out.  So last night I get in bed and I realized there was suddenly no usable pressure.  The machine ran and blew air but with the mask on my face it was weak and didn't make enough pressure to help inhalation.  The pressure was suddenly so low that I couldn't even create my normal leak at the bridge of my nose even when trying. It actually felt like I was drawing against the machine when inhaling.  I tried unplugging/plugging, I tried upping the min pressure, disabling ramp.  Nothing helped.

This morning I called my vendor and went through tech support, they had me turn off BiFlex.  It seems this was the problem, the machine now blows hard enough like it's supposed to.    Hopefully disabling BiFlex won't have an effect on my comfort/how well I sleep, but at least I don't have to figure out how to get an exchange machine during a pandemic.

I'm posting this to help others because last night I tried searching the forum and google and found nothing in terms of useful information.  (The closest I found were some threads on another forum where people were more concerned about demanding the people wit the problem demonstrate the pressure was low by making a DIY manometer before anyone would actually help).

TLDR; If your machine suddenly stops making pressure, try disabling BiFlex.

I had a similar problem, but don't know if BiFlex was involved. See http://www.apneaboard.com/forums/Thread-...sure-drops for the details. Resolved (almost) by changing to a ResMed machine, but it's a work in progress.

You probably can check into potential repair, if deemed necessary, but it's possible the machine blower died on you. If true, maybe it'll get replaced. If that's not the case, a newer ResMed would make a great replacement that would serve better and more reliable.
