Is Respiratory Rate an Adequate Indicator of Respiratory Distress During Weaning? A Comparison of Weaning on Pressure Support vs. Proportional Assist Ventilation.

Detailed Summary

The study hypothesis is that reducing patient-ventilator asynchrony will reduce time required to wean from mechanical ventilation. The purpose of this pilot study is (1) to assess study feasibility in terms of recruitment, protocol adherence and efficacy of the intervention for reducing asynchrony, (2) to assess baseline rates of asynchrony and outcomes in the control arm in order to perform sample size calculations, if needed, for further, larger studies designed to detect differences in weaning time in specific, predefined populations and (3) to examine how often ineffective triggering (and therefore reduced ventilator respiratory rate) at higher levels of pressure support lead to a false conclusion that higher levels of support are needed to diminish respiratory distress.
