Early change in ventilatory ratio during prone positioning and 28-day mortality in patients with ARDS: a retrospective cohort study with exploratory eICU assessment
Prone positioning (PP) improves outcomes in moderate-to-severe acute respiratory distress syndrome (ARDS), but early bedside markers that reliably characterize physiological response remain uncertain. The ventilatory ratio (VR), calculated from minute ventilation, PaCO2, and predicted body weight, may capture ventilato...
