pulmonary artery wedge pressure [PAWP] value to differentiate precapillary PH from PH caused by left-sided heart disease), there is growing realization that the waveforms’ characteristics themselves may provide additive, clinically relevant data. For example, in patients with PH, the presence of large V-waves on the PAWP
PAWP was repeated due to abnormal waveform, incomplete wedge and over wedge. A valid PAWP was obtained in the right pulmonary circulation in 168 (86%) patients, and in the lower third in 134 (69%), middle third in 58 (30%), and upper third of the lung in 3 (2%) patients.
Mean PAWP, or PAWP averaged over the cardiac cycle, encompasses the pressure waveform during both systole and diastole, and best represents the ambient pressure of the pulmonary venous circulation.

Identify normal ranges for haemodynamic values measured from a pulmonary artery catheter. Reflect on the nursing management of a pulmonary artery catheter. Introduction:
24 lut 2020 · Abnormally prominent v-waves on the pulmonary artery wedge pressure (PAWP) waveform (F) also makes interpretation and adjudication more difficult. EXP indicates expiration; and INSP, inspiration.
6 lis 2020 · Patients with an exercise PP/PAWP ≤2.5 demonstrated preserved linkages between left heart filling and PA pressures. An elevated exercise PP/PAWP identified patients with the highest PA pressures, limited PAWP responses to exercise, and altered pulmonary vascular to PAWP relationships.
10 lut 2021 · In this first part, the insertion techniques, interpretation of waveforms of the PAC, the interaction of waveforms with the respiratory cycle and airway pressure as well as pitfalls in waveform analysis are discussed.
