TL;DR: In this paper, a calorimetric heat flux gauge was designed and fabricated to quantify the convective component of this heat transfer, which was accomplished by inputting the measured timewise varying gauge temperature into a data reduction program and calculating the desired convection heat transfer coefficient.
Abstract: INTRODUCTION Bair Hugger® warming therapy is used on surgical patients to minimize physiologic complications due to inadvertent hypothermia. It has been reported that anesthetic-induced vasodilatation brings about a drop in the patient's body core temperature during surgery and is responsible for metabolic stresses during the recovery period [1]. Bair Hugger® warming therapy utilizes both convective and radiative modes of heat transfer to transport heat energy from a wanning cover to the patient's cutaneous layer. In order to quantify the convective component of this heat transfer, a calorimetric heat flux gauge was designed and fabricated. This was accomplished by inputting the measured timewise varying gauge temperature into a data reduction program and calculating the desired convection heat transfer coefficient .
