Power, Duration, and Compliance: Reframing Risk of Ventilatory-Induced Lung Injury With the Risk-Adjusted Mechanical-Power Score

Key Points

This research aims to redefine lung injury risk in ventilated patients by integrating mechanical power parameters.
Analyzed the interaction between power intensity, duration, and respiratory compliance.
Developed a risk-adjusted mechanical power score to assess ventilatory impacts.
Suggested prospective validation for individualizing ventilator settings.
Identified a dynamic interplay between power, duration, and compliance affecting lung injury risk.
Proposed the risk-adjusted score as a clinically useful tool for ventilator management.

Abstract

A single "safe" MP threshold is insufficient for guiding ventilation; the risk of lung injury is governed by a dynamic interplay of power intensity, duration, and the patient's respiratory compliance. The risk-adjusted MP score unifies these factors into a time-varying, clinically interpretable metric that warrants prospective validation for personalized ventilator management.
