Investigation of a human organism systemic response to local heating with the use of FPA-based infrared thermography

Focal plane array (FPA)-based infrared thermography (IRT) method was used in dynamic regime to investigate the human organism systemic reaction developed in response to a dry heat transient application to a part of body (forearm). The used infrared camera high performance (100 fps) and high temperature sensitivity (of the order of 0.01 °C) enabled high-precision measurement not only of the extremities thermal response but also the external breathing characteristics by means of the sorption-enhanced IRT original approach. In the course of the forearm heating, both an increase in breathing rate and synchronous paradoxic decrease in both arms temperature were revealed.
