Pulmonary vascular resistance. Mean pulmonary vascular resistance as determined from arterial blood pressure and cardiac output. The first dashed line indicates the infusion of shed blood surrogate. The second dashed line indicates the infusion of epinephrine and Ringer's lactate. The horizontal line denotes the baseline value calculated from the PVR during the 10-minute resting period (prior to the shed blood surrogate infusion).
