Definition | Invasive measures | PH-group |
---|---|---|
PH | mPAP ≥25mmHg CI normal or reduced | 1–5 |
Precapillary PH | mPAP ≥25mmHg PVRi >3 iWU PCWP <15mmHg CI normal or reduced | 1,3,4,5 |
Postcapillary PH Passive Reactive (formerly: ‘out of proportion’) | mPAP ≥25mmHg PCWP ≥15mmHg CI normal or reduced DPD <7 mm Hg (adults) DPD ≥7mmHg (adults) | 2 |
CI, cardiac index; DPD, diastolic pressure difference; mPAP, mean pulmonary arterial pressure; PCWP, pulmonary capillary wedge pressure; PH, pulmonary hypertension; PVRi, pulmonary vascular resistance index.
