First Night on Bipap-Pretty Rough
#11
I also just started bi-pap with a resmed aircurve st machine .  Used a airsence apap since Feb and it cleared up my obstructive apneas but did not clear up my central apneas.  Started Friday and that was a rough night, pressures 14-19.  The second night was better and last night was great.  I absolutely need a full face mask as that is a lot of pressure with a lot of mouth leak. Using airtouch f20 with memory foam. It's a matter of allowing yourself to adjust to this crazy amount pressure but it is worth it to keep trying. First sleep study AHI was 90.  My third sleep study with just 40 with CPAP. With bi-level it was less than 3.  It's what I need to do to sleep well after year of not. Good luck.

Any thoughts on why you were prescribed ST instead of ASV?   Unless you have a low left ventricular ejection fraction ASV is the best solution for complex (obstructive + central) apnea.

Not sure, that's what my pulmonologist prescribed. My guess is insurance/Medicare climbing the latter of justification. May ultimately go to asv I'd st fails.

"A possible optimal pressure of 14cwp/9cwp was achieved: however supine sleep was not observed. (stayed on right side all night because of the wires-not typical-I move a lot)."

You will likely find you will move around a lot less once you get this sorted out. Pre-cpap I would wake with blankets twisted and wrapped all over me and a very unhappy wife. She now also has a cpap machine and we both sleep a LOT better. Good luck!
I use my PAP machine nightly and I feel great!

Astrodancer, the ST imposes constant high pressure support which will increase your central apnea, and make you dependent on the backup function, assuming it is strong enough. ASV is such an elegant approach because it simply targets your normal minute vent and lets you overcome hypopnea and apnea with just the amount of pressure support needed, and it leaves you alone to breathe on your own when you don't need it. ST is not the solution, but be patient and don't forget to complain frequently. It's your right to get the right treatment.

In australia the ST is more expensive than the ASV. It really depends on whether you have obstructive, restrictive or OHS lung function, that need the ST or the auto ST avaps/ivaps. The ASV is for normal lung function and not is as specialised for patients requiring more advanced treatment.

From machine or charts for auto-cpap, set the min 1cm below median pressure, or 2cm below 90/95%. max at 20cm for now. Forum will help you fine tune settings

Nearing a week of bi-pap.  Started Friday with ahi 14.1 and a lot of leaking and getting the hang of it with 5.9 3.8 2.7 2.7 1.7 0.7 with low leaks at 14 and 19 ramp 15 min.  Very happy with my progress.  My  sleepyhead charts are kind of boring now.
