Final answer:
During resuscitation, the heart should be controlled at a lower temperature to reduce damage and decrease metabolic needs.
Step-by-step explanation:
During resuscitation, the heart should be controlled at a lower temperature to reduce damage and decrease the metabolic needs of the brain and other organs.
When controlled hypothermia is used clinically, the body is cooled to 25-32°C (79-89°F) to help the heart muscle tolerate its lack of blood supply. In some cases, during open-heart surgery, the heart is cooled further and maintained at a temperature below 15°C (60°F) for the duration of the procedure.
