Are we neglecting extra-vascular pressures?
Letter to the editor in a scholarly journal
To the editor: We read with great interest Groombridge and colleagues’ article comparing central venous pressure at the superior vena cava and femoral vein sites.1 We completely agree with the conclusions drawn by the authors that superior vena cava pressure (SVCP) and femoral venous pressure (FVP) are two different pressure entities altogether.
Unfortunately, despite examining the influence of positive end-expiratory pressures (PEEP) and intra-abdominal pressures on SVCP and FVP, the authors did not point out how important it is to assess potential extra-vascular pressures when interpreting SVCP or FVP correctly when caring for critically ill patients.
