WebMar 2, 2024 · PRINCIPLE. The pulmonary artery wedge pressure is closely related to the left arterial pressure since there are no values in the pulmonary veins. Left arterial pressure is closely related to the left ventricular end diastolic (filling pressure of the left ventricle) When the catheter is wedged, it looks directly into the left side of the heart ... WebJun 30, 2015 · Now, we wedge the catheter. The catheter with the inflated balloon is advanced further, until the PA waveform disappears, and a venous-looking waveform appears. This is the wedge waveform. It indicates that the pulmonary artery is occluded. The pressure here should also be 6-12 mmHg, like the PA diastolic pressure.
