Hypothermia• Outgassing• Occurs at tissue level when cooling• Occurs at heat exchanger when rewarming• Maintain a 12°C gradient• Cool at a rate of 1°C per minute• Rewarm at a rate of 1°C per three minutes• Protein denaturation occurs at 42°C
Blood Gas Strategies• pH stat maintain normal temperaturecorrected values for pH and PaCO 2• As blood temperature decreases, CO 2becomes more soluble• To maintain a constant pH and PaCO 2 ,CO 2 must be added
