Comparison of PVRi calculated with the Fick principle and with CMR flow on inhaled 100% O2 and 40 ppm NO.
a Correlation between PVRi calculated with the Fick principle and with CMR flow on inhaled 100% O2 and 40 ppm NO (n = 45 paired calculations). b Bland-Altman plot of the difference in PVRi calculated with the two methods, and mean PVRi with the two methods. PVRi: pulmonary vascular resistance index
