PAWP measured by convention at end-expiration at end-diastole (ECG p wave) phasic blood flow and pressure ceases static column of blood between catheter tip in pulmonary artery and the left atrium must be in West Zone III otherwise trace will show respiratory swing (reflects alveolar pressure in West Zones I and II)
Pulmonary Artery Wedge Pressure (PAWP) - Weebly
https://hemodygs.weebly.com/pulmonary-artery-wedge-pressure-pawp.html
When the tracing changes from arterial to atrial, the catheter is said to be wedged and PAWP is measured at the end of expiration. Measures pressures generated by the left ventricle. Used to assess left ventricular function. Normal PAWP is 8-12 mmHg. PAWP is increased in left ventricular failure and pericardial tamponade.

The LVEDP is a surrogate measure of LV preload and LV diastolic operating compliance. The mean PAWP, on the other hand, is a better reflection of the cumulative hemodynamic impact of ventriculoatrial coupling and its operating compliance on the pulmonary circulation. When trying to calculate pulmonary arteriolar resistance or evaluate the cause ...

The a wave is the first upward deflection seen on the wedge tracing after the p wave on the ECG and represents atrial systole. It is followed by the x descent, the v wave representing ventricular...

However, echocardiography generates PAP estimates that correlate only modestly with RHC findings in individual patients, and PVR, pulmonary artery wedge pressure (PAWP) or right atrial pressure (all prognostic in PH) cannot be determined precisely non-invasively. Thus, optimal hemodynamic phenotyping requires RHC.

CHECKING A PAWP READING PAWP is recorded by inflating the balloon and letting it float in a distal artery To begin, verify that the transducer is properly leveled and zeroed Take the pressure reading at end expiration. Note the amount of air needed to change the PA tracing to a wedge tracing (normally 1.25-1.5 cc) REMOVING THE CATHETER

The P-wave, PR interval and PR segment. ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex. The PR interval is assessed in order to determine whether impulse conduction from the atria to the ventricles …
