Not new to CPAP, minus one lung - Tyler NZ - 01-19-2024
Just found this board, a bit of my background in summarized:
* Got referred for a sleep study 11 years back (public funded here in NZ). Result was 47 AHI
* Got a philips system one supplied, pressure 13 CPAP. Used it for about 7 years, the when it went in for a service it came back with no humidifier (lol)
* Fast forward another 4 years, then last year found out I had lung cancer, consequently had my whole right lung removed a few months ago
* Surgeon recommended 6 weeks no CPAP post surgery, which I did
* Decided I wanted to prioritize my sleep quality, so started researching for a new machine. Realized through this process that the philips machine I was using for the last 11 years was recalled years ago, so stopped using it immediately. Still furious that I wasn't notified
* Got sent a replacement Resmed A10 through our public system, have been using it 3 days now. Really enjoying it
I have downloaded Oscar ready to start looking at me data and optimizing my therapy. I have set the A10 up on APAP 8-18, so far average pressure is showing as 12.7.
I think it will be interesting to see if/how my data & therapy are different now I am living on only one lung. I am quite focused on my 02 saturation, I know that's not normally a metric that's in high focus but for me my ability to maintain & recover my 02 levels is a lot less than a normal (2 lung) person.
I would be really interested to hear from anyone on here that has therapy that have also had a pneumonectomy (lung removed) and your experiences with therapy.
Also looking at the possibility of using an 02 sensor that can feed into Oscar, though I will need to figure out how to actually do that. If anyone has any links or guidance for the process of how I can get both sets of data aligned into Oscar (a10 and 02) and how that even works, that would be great.
Sorry for the long post!!

Tyler, I'm glad to hear you got a Resmed Airsense 10 in place of the Philips unit. One of the advantages of the Resmed is that it can provide bilevel pressure using the exhale pressure relief (EPR) feature. This is true bilevel with a exhale (EPAP) pressure channel and higher inspiratory (IPAP) pressure channel, with up to 3-cm of difference between them. This can give you a slight mechanical assist in obtaining a normal tidal volume, although you will certainly see some volume difference with only one lung. I'm looking forward to helping you to optimize, and would like to suggest that you start in Autoset Standard mode with a minimum pressure of 9.0, maximum pressure 13.0 and EPR full-time at 3.

[attachment=58615][attachment=58615]thanks Sleeprider, yes if nothing else it should be interesting! I have just purchased a card reader so I can get a first look at my data. Its only 3 days, but I will attempt to attach them, and keen for any initial feedback. If you want any zoomed in stuff, or I have the screenshots wrong let me know!
Also thank you for the tips, I havent touched my EPR settings yet, but based on your feedback I definitely should! really keen on if anything in those charts changes your initial view?

The baseline data looks good, and lets us know your 95% flow limit is about 0.13 and your tidal volume is 480 mL which is remarkable considering you have one lung. Adding EPR should reduce flow limitation which results in higher pressure and potential arousals. I'm curious to see how you react or benefit from use of EPR.

I was camping last night so no machine, but I will try using the EPR this week and reupload/report back! Thank you for the advice
