Mathematical Modeling of Skin Temperature Changes with Whole-Body Cryotherapy

The physical processes taking place in the cryochamber during the therapeutic treatment were investigated. The analysis of temperature fields during whole-body-cryotherapy (WBC) in skin integument and volume of cryochamber has been investigated. The analysis was implemented based on the modeling of non-stationary heat transfer through a multilayered object. The study was performed using the finite element method. The calculations were based on the equations of heat transfer process in solids and biological tissue with internal heat source and laminar flow. The modules were combined using Multiphysics interface. Main results. The computer model created allows the calculation of thermal field dynamics in the skin of a patient body during and after WBC. Mathematical model of WBC allows the estimation of such parameters as coolant velocity and temperature, session exposure, cryochamber design and individual features of WBC object. The model performed allows the analysis of WBC parameters and their impact on skin integument temperature.
