The upper limit of normal of mean pulmonary artery pressure (MPAP) is 20 mm Hg ( 10 ), with a cut-off value for the diagnosis of pulmonary hypertension of 25 mm Hg ( 1 ). The upper limit of normal of the pulmonary artery wedge pressure (PAWP) is 12 mm Hg, with a cut-off value for the diagnosis of left heart failure usually agreed of 15 mm Hg ( 1 ).

the waveform of the pa pressure tracing became flattened, similar to a wedged position tracing, but resumed a normal configuration and a pressure of 21/12 mmhg on withdrawing the pa catheter from 40 to 37 cm. slow inflation of the balloon of the pa catheter unexpect- edly resulted in a fluctuating waveform …
Pulmonary Artery Pressure (PAP) - Hemodynamic Monitoring
https://hemodygs.weebly.com/pulmonary-artery-pressure-pap.html
The pulmonary artery pressure (PAP) is helpful in diagnosing many clinical conditions. The PAP tracing has an initial positive upstroke secondary to when RV systole occurs, and a dicrotic notch is formed on the downstroke when the pulmonary valve closes. The PAP is elevated in some high-flow states: ~ Hypervolemia ~ Left ventricular failure

The pulmonary artery pressure tracing (Ppa) is evidenced by an abrupt rise in diastolic pressure ( Fig. 28-5 ). With further advancement, a fall in mean pressure and transition to an atrial waveform (see below) signals transition to a pulmonary artery occlusion (wedge) pressure (Ppw) ( Fig. 28-5 ). FIGURE 28-5

INTRODUCTION. The pulmonary artery catheter (PAC; Swan-Ganz or right heart catheter) can be used for a variety of clinical purposes. Interpreting hemodynamic data from PACs is important for the diagnosis and management of a range of conditions including shock and pulmonary artery hypertension ().The interpretation of hemodynamic values and pressure …
Comparison of RV and PA Waveforms | LHSC

The RV pressure rises as a result of isovolumetric contraction. During isovolumetric contraction, the RV pressure rises while all 4 valves remain closed. The RV pressure must increase until it becomes higher than the pulmonary artery pressure. This pressure difference is needed to open the pulmonic valve. The rise in RV pressure coincides with ventricular depolarization (QRS).

Pulmonary Artery Pressure • Systolic phase - steep rise occurring during the Right Ventricular ejection after the opening of the pulmonary valve. • This rise is followed by a general decrease in pressure whilst blood is being ejected from the right ventricle until closure of the pulmonary valve. • Closure pulmonary valve - diachrotic notch
