A Method of Partitional Calorimetry of Individual Skin Areas.
Abstract
A method of partitional calorimetry which is applicable to the measurement of the radiative, convective and evaporative heat losses from a limited skin surface (forehead, palm, thigh, etc) was based on measurements of skin and environmental temperatures and cutaneous evaporative rates. Radiation was calculated from the Stefan-Boltzmann equation; convection was estimated from the air insulation which in turn was approximated from the application of the diffusion equation to the evaporation of water. The local evaporative rates were measured by means of desiccating capsules. The sources of error are described. The total body losses of heat via radiation and convection from the skin cannot be obtained from the sum of the weighted regional rates. For reasons given in the text, this is not a criticism of regional partitional calorimetry. Total cutaneous evaporation is closely approximated by the sum of the weighted regional rates. (Author)
