Mechanical Power in Pressure-Controlled Ventilation: A Simple and Reliable Bedside Method.

ABSTRACT:

Background

Mechanical power (MP) represents the amount of energy applied by the ventilator to the respiratory system over time. There are two main methods to calculate MP in mechanical ventilation. The first is the geometric method, which directly measures the dynamic inspiratory area of the pressure-volume loop during the respiratory cycle. The second involves using various algebraic equations to estimate MP. However, almost all calculations are either complex or not reliable compared with the geometric method, considered the gold standard. This study aimed to develop an easy to use, reliable equation for bedside calculation of MP and to compare its accuracy with other existing equations for calculating MP.

Methods

In a preliminary study, we measured MP in 56 cases who were
