The 10 cm reference point overestimates CVP; cross-sectional data leaves open standardization of alternative bedside methods versus catheterization.
How do different methods for determining central venous pressure compare to catheter studies in patients undergoing cardiac catheterization?
Using a reference point 10 cm above the supporting surface for central venous pressure yields falsely high values compared to direct catheterization measurements.
Debrunner et al. (1969) studied this question.
