Possible equilibration of portal venous and central venous pressures during circulatory arrest.

The mean circulatory filling pressure technique has been used to assess total body venous tone. It involves measuring central venous pressure (CVP) at 5-8 s following circulatory arrest. This study examines if CVP and portal venous pressure (PVP) equilibrate when circulation is stopped by inflating a balloon implanted in the right atrium. CVP and PVP were… CONTINUE READING
