difference between APAP and BI Pap - jerry1967 - 03-22-2018
What is the difference between APAP and BI Pap and ASV please?
RE: difference between APAP and BI Pap - Gideon - 03-22-2018
CPAP - Fixed Pressure (IPAP)
APAP - Any class of machine, CPAP, BiPAP, ASV that has an algorithmic control of the machines pressures
Auto CPAP - Automatic control of IPAP
BiPAP/BiLevel - Fixed pressures based on EPAP with PS Pressure Support. Capable of higher pressures than Fixed CPAP, Vairants are capable of timed backup breathing
Auto BiPAP - Automatic control of EPAP and PS (IPAP = EPAP + PS)
ASV - a specialized variant of CPAP that automatically detects events and intervenes to prevent OA, Hyponea, and CA.

If I set my APAP to Max pressure of 16 with a minimum of 12 with pressure support of 1, which drops the exhale pressure to 11, Would that be the same exhale treatment as Max pressure of 16 and minimum of 13 with pressure support of 2?
Would it be the same as a Max pressure of 16 and minimum of 14 with pressure support of 3?
All three situations have to same exhale pressure of 11. Would all three situations be considered the same exhale treatment with the same results?

With min pressure 12, max 16 EPR 1 you will get these values IPAP/EPAP respectively. 12/11 13/12 14/13 15/14 16/15. EPR 2, 12/10, 13/11....16/14.
EPR 3, 12/9, 13/10...16/13
RE: difference between APAP and BI Pap - Sleeprider - 03-24-2018
APAP 12 to 16 EPR 1 yields a pressure range of 12/11 to 16/15. (IPAP/EPAP)
APAP 13 to 15 EPR 2 yields a pressure range of 13/11 to 16/14.
APAP 14 to 16 EPR 3 yields a pressure range of 14/11 to 16/13.
APAP 14 to 18 EPR 3 yields a pressure range of 14/11 to 18/15. This is the full original EPAP range and more closely approximates how we would use Pressure Support in bilevel therapy.
EPAP tends to control obstructive apnea and reducing EPAP pressure may allow more events.
EPR (or pressure support), can improve hypopnea and flow limitations, and may increase CA events.
Your setting scenarios all maintain the same minimum EPAP, but allow for a lower maximum EPAP. That is probably okay, but you could maintain the max EPAP by also increasing maximum pressure. As EPR increases, we would normally expect the settings to feel more comfortable and perhaps reduce hypopnea, however in a few individuals, this may also increase CA events.

Would setting the minimum at 12 with pressure relief of 2 be the same as setting the minimum at 11 with pressure relief at 1? Would a person get the same therapeutic results?
RE: difference between APAP and BI Pap - Sleeprider - 03-26-2018
At very low EPR levels, the feature is more about comfort. I would not normally expect a therapeutic difference with those settings, or for that matter 11 with 1-EPR.
