Reliable Estimates of Power Delivery During Mechanical Ventilation Utilizing Easily Obtained Bedside Parameters.

ABSTRACT:

Background

Ventilator-induced lung injury (VILI) requires repetitive transfer of energy from the ventilator to the compromised lung. To understand this phenomenon, 2 sets of equations have been developed to partition total inflation energy into harmless and hazardous components using an arbitrary level of alveolar pressure as a threshold beyond which further energy increments may become damaging. One set of equations uses premeasured resistance and compliance as inputs to predict the energy that would be delivered by typical ventilator settings, whereas the other equation set uses observed output values for end-inspiratory peak and plateau pressure of an already completed inflation.

Methods

Our aim for this study was to compare the relative accuracy of these equation sets ag
