Proportional Assist Ventilation (PAV): A New Strategy for Mechanical Ventilation in Low Birth Weight Infants. † 1038

Abstract

During PAV, the airway pressure increases in proportion to inspiratory flow and tidal volume throughout each spontaneous inspiration such that partial respiratory unloading of airway resistance and lung elastic recoil are induced. In contrast, fixed inflation pressure and timing profiles are imposed during Assist/Control (AC) and Conventional Mechanical Ventilation (CV). We compared PAV, AC, and CV in a randomized, three period crossover study.
