Hemodynamic pattern as a function of ΔCI and ΔGEDVI between T₁ and T₃. a Symbols are individual values for each prone position session. Broken lines are threshold values for significant changes in CI (+ or − 15%) and GEDVI (+ or − 15%). Red dots refer to patients with ACP. Blue dots refer to patients without ACP and without fluid challenge between T₁ and T₃. Green dots refer to patients without ACP and with any fluid challenge between T₁ and T₃. b Bars are percentage of patients falling in each category. CI, cardiac index; GEDVI, global end-diastolic volume index; ACP, acute cor pulmonale; ΔCI, change in CI; ΔGEDVI, change in GEDVI; PP, prone position; T₁, before prone position; T₃, end of prone position session
