Bedside Adjustment of Proportional Assist Ventilation to Target a Predefined Range of Respiratory Effort*

Abstract

This first study assessing the clinical feasibility of titrating proportional assist ventilation with load-adjustable gain factors in an attempt to target a predefined range of effort showed that adjusting the level of assistance to maintain a predefined boundary of respiratory muscle pressure is feasible, simple, and often sufficient to ventilate patients until extubation.
