Noninvasive quantification of energy transfer during mechanical ventilation
Abstract
This study presents and validates a noninvasive method that uses only airway pressure and flow signals to dynamically quantify energy transfer to mechanically ventilated patients while accounting for respiratory effort. Equations derived from a classic one-compartment model accurately predicted individual breath energy transfer during volume- and pressure-controlled ventilation. The method provides a physiological framework to explore, in real-time and non invasively, the dynamics and clinical significance of ventilator-to-patient energy transfer.
