Computer analysis of the thermal state of the object after cryotherapy

Abstract

In this work, experimental data are presented that allows one to estimate the relative amount of heat release. It also provides the opportunity to state the general tendency of its change over time for patients with various individual characteristics of the organism. An important indicator of safety and effectiveness of cryotherapy is the temperature of the skin surface Tk, which should not fall below -2 °C during exposure. It is also planned to propose a method for studying the dynamics of Tk and heat flux from the human body using a thermoelectric module (TEM). The paper evaluates the experimental data on the TEM current changes during and after cryotherapy. Also, dynamics assessment of heat flow during cryotherapy is given and the possibility of evaluating Tk will be shown. It is planned to get an overall picture of the process of heat exchange of the measuring device with the skin of the test object. The results allow us to make recommendations regarding the duration and intensity of cryotherapy.

Influence of Body Heat Loss on Temperature and Velocity Fields in a Whole-Body Cryotherapy Chamber

“…It is worth noting that, during the 3 min cryotherapy session, the surface heat flux decreases by approximately 10%. However, Yerezhep et al [26] estimated that, during a partial-body cryotherapy session, the thermal flux decreases by about one-third. It should be emphasized that the value of the flux is inherently dependent on the air temperature within the cryotherapy chamber and the prevailing airflow conditions.…”
