Hemodynamic Response of the Dog to Thermal Radiation

Abstract
The response of cardiac output, arterial pressure, right atrial pressure, plasma volume, hematocrit, blood volume, heart rate, and plasma proteins, in the dog after exposure to severe thermal radiation, was described. Evidence is presented which indicates that volume loss in the burned dog is not the initiating factor of burn shock. Rather, a precipitous decrease of flow occurs prior to major changes of either plasma or blood volume.
