Mellen Bipap Help

Mellen Bipap Help
Hello everyone,

I've been having sleep issues for many years now and finally decided it was bad enough that I should try to get it taken care of! I had to leave my last job soon after I had my at home sleep study so I decided to purchase a used Aircurve 10 Vauto instead of waiting a couple more weeks to go through this whole process of acquiring a cpap through my next employer's insurance. Any help you all can give me would be very much appreciated!

I had to take individual screenshots of my Watchpat sleep study because the fax they sent me was of terrible quality. It appears with an RDI of 11.5 I might possibly have UARS? I also have the symptoms to go along with it such as daytime tiredness, fatigue, brain fog. If the sleep stage data is correct I don't appear to be going into REM sleep like I should? That's why I decided to purchase a used bipap as that seems to be what's suggested on here for treating UARS.

I had my first night of using the AirCurve last night. I'll attach the OSCAR data in a comment post below this. I just used generic suggested starting settings that I found on here. They were as follows:


Mode: VAuto
Min EPAP: 4
Max IPAP: 15
PS: 4
Tmin: 0.3s
Tmax: 3s (I take long breaths so I extended this. Was that a mistake? I think I have fairly narrow airways)
Trigger: Medium
Cycle: Medium

I was using a Nasal mask. The first like 2 hours of data I didn't really fall asleep, I was just drifting in and out of light sleep, probably because I wasn't used to the mask. Then there's the flow gap in the middle where I took it off for a little bit and put it back on. The rest of time from like 4am-7am is where I actually fell asleep with the mask on. I believe I may have woken up a couple times intermittently though.

Attached is the OSCAR data. I believe I did this right. Why does my flow rate and Tidal volume drop so much towards the end?

Welcome to the forum.
Your numbers look good so no change in settings.
I would like to see what happened when your breathing went shallow (comparatively).  You are right that this MIGHT be UARS, only MIGHT.

So I would like to see the transitions, where your flow rate shrank considerably. at
5:10
5:52
6:30 and
6:40 
That is a 2-3 minute view, I want to clearly see the breath wave form.  Only the first graph please. This way ewe can see what happened

RE: Mellen Bipap Help
Hi Bonjour,

Thank you so much for your response! I have attached waveforms from several points. I don't know if I see the transition you mentioned at 630 and 640, but I included them anyways. It seems that my breathing before those events, around 4:40 are regular and what I think is correct, and then shortly before those transitions the waveform stretches out around the 0 flow rate mark.

It seems that it has possibly improved my symptoms? I'm as tired as I normally am, however I got significantly less sleep than normal and still feel about average.
