Figure 1From: Acute hemodynamic effects of inhaled nitric oxide, dobutamine and a combination of the two in patients with mild to moderate secondary pulmonary hypertensionFlow-pressure diagram showing the difference of MPAP and PAOP (MPAP-PAOP) and cardiac index. The dashed lines indicate the isoresistance lines from 600 to 300 dyne/s/cm5. INO, inhaled nitric oxide; MPAP, mean pulmonary arterial pressure; PAOP, pulmonary artery occluded pressure.Back to article page
