Abstract
Summary
An attempt has been made to show some changes under hypothermia with control studies on two factors, repeated plasma volume determination and hyperventilation. A moderate amount of blood seemed to be trapped away from circulation at lowered body temperature (4-6). Since blood clotting involves the action of enzymes it might be expected that coagulation would be retarded by lowered temperature. Increases in bleeding and clotting times at 23‡-25°C were highly singnificant.
