Web3 de nov. de 2024 · PAOP or PAWP is pressure within the pulmonary arterial system when catheter tip ‘wedged’ in the tapering branch of one of the pulmonary arteries. in most patients this estimates LVEDP thus is an indicator of LVEDV (preload of the left ventricle) normally 6-12mmHg (1-5mmHg less than the pulmonary artery diastolic pressure) WebThe RA pressure is the “filling pressure” of the right heart. It reflects venous return to the RA and RV end-diastolic pressure. Normal RA pressure is 3–7 mmHg ( Table 2 ). The classic RA waveform consists of three discrete positive and two negative deflections ( Fig. 2 ).
