Fig. 5From: Lung distribution of gas and blood volume in critically ill COVID-19 patients: a quantitative dual-energy computed tomography studyCorrelations between PaO2/FiO2 ratio and lung aeration and gas:blood volume mismatch. Gas:blood volume mismatch is the percent of lung mass accounted for shunt, dead space and non-aerated non-perfused regions. *Significant correlationBack to article page
