Abstract
Due to the many unknown factors regarding the inducing of hypothermia in post-cardiac arrest patients, an energy and exergy analysis was performed in one of the techniques established in medical literature. Using a C++ code to simulate the body of an adult man under anesthesia and calculate the energy and exergy balance on different sections of the body for every time step during the procedure. Besides obtaining the global efficiency, an analysis of temperature profile and control was assessed, giving a special focus on the brain, target of the therapy. It was concluded that the cooling pads provide a slow response on the brain temperature as it reduces the body temperature to dangerous levels, although keeping acceptable exergy efficiency
