Pulmonary Artery Pulsatility Index (PAPi) PA systolic: 35 mm Hg mm Hg PA diastolic: 15 mm Hg mm Hg Right atrial pressure (CVP): 8 mm Hg mm Hg PAPi: 2.50 What PAPi measures: ratio of pulmonary artery pulse pressure to right atrial pressure (RV pulsatility vs congestion). Rule-of-thumb interpretation: Normal / healthy RV: > 1.5–2.0 RV dysfunction: < […]
