Abstract

In this paper, we reviewed the temperature fields and heat flux emanating from the target tissues of the object. The influence of low temperatures on the integumentary tissues of the object with cryotherapy treatment on the given object or the whole-body cryotherapy (WBC) procedure was analysed. WBC is a method connected with the use of cryogenic gas for the treatment and prevention of certain diseases. The results that are shown in this article are derived using a mathematical model of heat exchange between the flow of a gaseous medium (liquid nitrogen vapor) and a biological object (an object of WBC impact) in a three-dimensional non-stationary formulation. The study and construction of the model was carried out using the finite element method. The computer model allows you to calculate the dynamics of the thermal field in the skin of the patient's body during and after the WBC. Computer simulations in the future could increase both safety and comfort of cryotherapy.
