The validity of extrapolating central venous pressure (CVP) to left ventricular (LV) filling pressure as gauged from the pulmonary artery wedge pressure (PAWP) was investigated in 9 subjects undergoing lung resection. Correlations existed between CVP and PAWP before, during and after surgery and between changes in CVP and PAWP during surgery. There was a wide scattering of the data around the regression lines, and an inability of the CVP and changes therein to predict the actual and directional change in PAWP in specific individuals. Caution is advised in assessing the LV filling pressure from the CVP in patients undergoing lung resection during any phase of the peri-operative period.
