Table 1 Changes in mPAP, PWP and PVR from baseline to pulmonary hypertension

From: A pig model of acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction

Pig Baseline (BL) Pulmonary hypertension (PH)
FiO2 mPAP (mmHg) PWP (mmHg) CO (l/min) PVR (dyn s/cm5) FiO2 mPAP (mmHg) PWP (mmHg) CO (l/min) PVR (dyn s/cm5)

  1. Both mPAP and PVR increase with reduction of FiO2 and globally induced hypoxic pulmonary vasoconstriction
  2. FiO 2 fraction of inspired oxygen, mPAP mean pulmonary arterial pressure, PWP pulmonary wedged pressure, CO cardiac output, PVR pulmonary vascular resistance
