"OVERCOMING THE LIMITATIONS OF
CONVENTIONAL HEMODYNAMIIC MONITORING"

Pulse Flow Changes in a Porcine Model of Acute Hemorrhagic Shock

There is a research program at the Uniformed Services University of the Health Sciences in Bethesda, MD in which oxygen consumption and debt are measured in pigs that are acutely bled to a predetermined mean blood pressure and held at that pressure for about 4 hours or until the animal dies. We measured PPV in the forelimb of one such animal. We found that in this one animal that changes in PPV tracked very closely with changes in cardiac output.
