Figure 2From: Uneven distribution of ventilation in acute respiratory distress syndromeLinear regression between EELV measurements by rebreathing of sulphur hexafluoride (EELVSF6) and by computed tomography (EELVCT) obtained in 25 ARDS patients. The dotted line is the regression line EELVSF6 = 0.4EELVCT + 0.3 (r2 = 0.72; P < 0.001).Back to article page
