new guy here. I realize this is an old thread. Google has found it for me when researching for BIPAP use for central apnea. At home I use AirCurv3 10 ASV and with success so far (whole 3 months) fighting severe complex apnea. Efore treatment started it was giving me AHI of 50
However for travel I cannot afford a second ASV and was researching other options. After reading this discussion I decided to give an Aircurve 10 Vauto a try. Bought it used with low milage from Supplier #2 (great transaction, helpfull people).
After experimenting using the info from this thread:
1. So far I am not able to find settings which would work for me (reduce central apnea enough) in BIPAP. Niether “S” mode nor “VAuto”.
2. Best results achieved so far are in CPAP mode with pressure 10 and EPR 3 cmH2O. I was able to reduce AHI to 9 - 10, which I think is OK for the purpose of travel, definitely better than 50.
I hope the below helps somebody.
Please note that the trigger/cycle settings in BIPAP mode on the AirCurve 10 are not direct sensitivity settings. Page 15 of the manual states:
————————
Trigger: Set the level of inspiratory flow above whichthe device changes from EPAP to IPAP.
Cycle : Set the level of inspiratory flow below whichthe device changes from IPAP to EPAP.
————————
And the low flow means the higher sensitivity. So if you want highest sensitivity than set those parameters to “very low” and not to “very high”. If you set it to “very high”, then you will have to create a lot of flow on your own before the machine starts helping you. Counterintuitive.
Cheers.
