Is he saying ASV is always superior to ABPAP? Is there an objective means to measure REM consolidation without an in-lab titration study? Which sleep labs do this level of study?

RE: flow limitations acceptable levels
Is this due to the pressure and volume of air being delivered differently and how that impacts expiratory resistance?
ASV - variable PS with varying pressure and (nearly?) constant volume, least expiratory resistance ABPAP - fixed PS with varying pressure and volume - volume better maintain by PS, less expiratory resistance APAP - varying pressure and volume Not sure that understanding is correct? How does ASV maintain volumes?

Resmed ASV algo aims for constant minute ventilation and Phillips ASV for constant tidal volume, I believe. Could be vice versa. Minute ventilation is respiratory rate multiplied by tidal volume, and so is a function of volume. ABPAP is auto-bilevel. Can auto PS and pressure. ASV is breath-by-breath changes in IPAP, also capable of adjusting EPAP to eliminate events, plus backup rate. |
