- All haemodynamic data was derived from pulmonary artery catheter use unless otherwise stated. mPAP, mean pulmonary artery pressure; PVRI, pulmonary vascular resistance index; PAOP, pulmonary artery occlusion pressure; PAP, pulmonary artery pressure. Wood units (mmHg/L/min) are multiplied by 80 to convert to standard metric units (dynes.sec.cm−5). Normal values for PVR range from 0.3 to 1.6 Wood unit.
