A Nomogram of Weaning Failure for Critical Ventilated Patients in High-Altitude Areas: A Single-Center Cohort Study Using Lasso Logistic Regression

Abstract

Conclusions: Hypertension, lower serum albumin, higher SOFA scores, smaller tidal volumes, and faster respiratory rates were independent risk factors for weaning failure in critically ill patients living in high-altitude areas. A prediction model for weaning failure was constructed, and it showed good prediction efficiency after verification.
