Hi all, new member here, recently self-diagnosed with OSA and finding my way with the help of great info from here and some of the other forums.
I was reading these guidelines: http://jcsm.aasm.org/articles/040210.pdf
And noticed that my current APAP settings of 15-20 cm H20 put me at a pressure level where consideration of a change to BPAP is recommended:
"If there are continued obstructive respiratory events at 15 cm H2 O of CPAP during the titration study, the patient may be switched to BPAP."
Furthermore, there is this comment regarding BPAP:
" An optimal minimum IPAP-EPAP differential is 4 cm H2O"
The level evidence provided for those recommendations has not been graded, nor has the evidence been summarized in any detail, so I am left wondering whether I should spring for a BPAP machine (I am doing this all out of pocket), and whether I would be better off with PS 4 than I am now with EPR 3.
Here is my data from last night as an example. I feel great and have no residual OSA symptoms to speak of.
Those early in the night clusters of OAs seem common for me. I'm guessing that they correlate with REM sleep.
I have only been on CPAP for a few weeks total now and have been working on optimal gear and improving sleep hygiene as well as weight loss (the eternal struggle), so it's possible that my results will improve over time without further increasing my pressure settings.
I really don't mind buying a BPAP if there is a good reason to do so. Fwiw, comfort has not been an issue for me. I am very comfortable at the current settings.
I guess my question boils down to this: Are the two recommendations I quoted based solely on achieving comfort, or is there some health benefit to having a higher PS when working with larger pressures? I have no asthma, COPD, or anything like that.
