New to Bipap auto

[FernandoC]

Hello everyone. I’m new here. I’ve been on Bipap( Dreamstation Pro) for about 5 years now. When the doctor wrote the prescription , the recommended pressure was 13/9. That was December 2017. Over the following months I adjusted the pressure myself because I was still suffering some bad episodes of apnea. After some experimentation I finally set for 12.5/14. I sleep fairly well and my AHI is almost always under 1 ( a lot of times under 0.5) 
My only concern is I have to sleep on my left side    otherwise I still have episodes.
Recently, Phillips finally sent me a replacement machine ( because the recall). I was very excited to find is a Bipap auto because I thought I finally will be able to get rid of those remaining apnea episodes. And now the reason of this post.
I’m not very familiar with these machines. I have an idea of how they work but I’m a little confused about how the min/max pressure support works and how to get the maximum benefits in my case.Should I change the pressure? So far It’s still 12.5 /14 but I set the machine to auto. It shows pressure support 1.5 (min/max) what it is? What should I do?
Thanks a lot in advance for your help!

Fernando, you can request the clinical manual which details the functionality and settings of these machines. Just follow the link for Setup Manuals at the top of this page.

The BiPAP Auto has the ability to set a minimum and maximum EPAP, and PS, which is the difference between IPAP and EPAP. With the BiPAP-S you were settled in on 14/12.5 pressure, which would be the same as EPAP 12.5 and PS 1.5. Not sure how you got to those settings, but we usually raise EPAP to address obstructive apnea, and increase pressure support or raise IPAP for flow limitation, hypopnea and snores. It sounds like you have decreased pressure support from 4.0 to 1.5, and I'm not sure why. Strongly recommend you download the Free OSCAR program so you can better visualize your therapy and share some charts on the forum. I am going to suggest some settings for the BiPAP auto based on the history you related.

Mode: Auto B
EPAP min: 9.0
IPAP Max Pressure 14.0
PS min 2.0
PS max 3.0

These settings will acquaint you to the auto BiPAP in a narrow range. If you download OSCAR, we can evaluate the results and decide better where to go from there.
