The thermal model of the rat under hemorrhagic shock hypothermia with microwave intervention

A whole body thermal model simulating heat distribution and temperature regulation in rats during hemorrhagic shock and during post-shock microwave core rewarming period was developed. An electrical circuit was used to simulate the thermal system and PSpice was used to analyze the circuit. The blood pressure drop and cardiac output decrease were considered in the simulation, and the set point temperature was investigated in the model. Linear decrease and increase of the set point temperature were assumed during the simulation of the shock period and the post-shock rewarming period, respectively. General agreement between the simulation result and experimental data was obtained
