Identification of focal ARDS using PF ratio: a cross-sectional study

Abstract

To check for any nonlinear relationship of focal ARDS with PF ratio, we fitted a logistic regression model using a restricted cubic spline with four knots and taking the PF ratio of the first knot as the reference level. Admission diagnoses were as follows: pneumonia (61 patients; 40.1%), non-pneumonia sepsis (19; 12.5%), chronic obstructive pulmonary disease (9; 5.9%), acute myocardial infarction (3; 2.0%), stroke (12; 7.9%), and other diagnoses such as massive hemoptysis, pulmonary vasculitis, and pneumonitis (48; 32.6%). Personalised mechanical ventilation tailored to lung morphology versus low positive end-expiratory pressure for patients with acute respiratory distress syndrome in France (the LIVE study): a multicentre, single-blind, randomised controlled trial.
