Aircurve 10 ST Pressure Drop - palmisland - 04-13-2016

Using a ResMed Aircurve 10 ST with pressures of 8 and 14, central apnea. Can't seem to adjust to sudden drop off of pressure when reaching the 14 pressure and exhaling, it goes immediately to 8. Any ideas on machine adjustments? Thanks for the help.

G'day Palmisland, welcome to Apnea Board.

You can obtain the clinician manual for your machine via the link at the top of this page. Please read the instructions carefully and make sure you select the exact right machine - there are hundreds of manuals available and it's easy to get them confused.

The clinician manual will give you all the details to interrogate your machine and see exactly how it's set up. Probably the second most important thing is which mode is it set in? Your machine can work in modes S, ST, T and CPAP, and each one behaves differently.

However the most important question is why are you using an ST to treat central apnea? It is indicated for obstructive apnea - you need an ASV for central. These are very expensive so it may be that you're being "tested" on the bilevel. If you "fail" that, the insurance company will then consider forking out for an ASV. Crazy stupid system but what can you do?

Hi palmisland,
WELCOME! to the forum.!
Hang in there for more responses to your post, much success to you as you continue your CPAP therapy.
Good luck to you with getting your problems straightened out.

I've split out the discussion about the definition of a ventilator. Perhaps members can now chime in and address Palmisland's original question.

I know of no way to tailor the transition from ipap to epap in ST mode. in S mode, you can turn on easybreath.

Thank you for the tips, I fear you're correct regarding insurance companies. The ST function has reduced my CA episodes from 37+ per hour with the ResMed S9 to less than one per hour with the Aircurve 10 ST so they (prescribing Dr. and clinician) are satisfied as am I with the performance. But there is still the little problem of the exhaling feeling like the air is being sucked from my lungs, yikes. I'll wonder around the clinician's manual for some ideas. Great form, thankful I found you all.

Progress being made. After moving my lower pressure of 8 to 9, absolutely no help, but then moving my higher pressure 14 lower to 13 things became easier on the exhale. The theory behind the lower upper pressure was the shorter distance to fall from 13 to 8 would be less abrupt and seem more natural to my breathing pattern. I doubt if there's any scientific support on the above but it's working, all events below 1.0 and 7 hours average per night. Palmisland
