Hypothermia increases cellular metabolism as the body attempts to increase its warmth during a surgical procedure
Indicate whether the statement is true or false.
ANS: F
Cooling of body tissues to a temperature as low as 78.8° F (26° C) in adults and large children and 68° F (20° C) in infants and small children, well below normal limits, decreases cellular metabolism and thereby decreases the need for oxygen by tissues. The decreased requirement for oxygen decreases bleeding. Hypothermia lowers blood pressure to slow the circulation and increases the viscosity of blood.
