Randomized trial demonstrates accurate prediction of ventilator pressure increases in critical care, suggesting early intervention potential.

The aim is to predict dangerous escalations in ventilator pressure using trajectory-based machine learning.
Analyzed 75,444 mechanical ventilation cycles from a multicenter dataset.
Developed two machine learning models: a baseline model and a trajectory model incorporating timing dynamics.
Validated models using a test set of 30% breaths and calibration analysis.
Baseline model achieved AUROC 0.904, indicating predictive capacity.
Trajectory model improved AUROC to 0.981 with 92% sensitivity and 99% specificity.
Critical features included pressure slope (20%) and consecutive rises (19%), indicating momentum.
