Heat Loss in Exposed Volunteers
The Journal of Trauma: Injury, Infection, and Critical Care, 1989Hypothermia is a common complication of major surgery and trauma. We studied this problem using Heat Flux Transducers to directly measure heat exchange between seven exposed volunteers and the environment. Heat exchange by radiation and convection was measured from the anterior chest wall and by conduction, between the back and a thermal mattress (CSZ,

Directional heat losses in radiometers
Applied Optics, 1986The heat flow mechanism in thermopile-based electrically calibrated absolute radiometers has been investigated in axial as well as radial directions. Solutions for transient and for steady-state flow of heat and temperature distribution have been obtained. Error functions associated with directional losses have been calculated. It is shown that, due to

Sweating as a heat loss thermoeffector
2018In humans, sweating is the most powerful autonomic thermoeffector. The evaporation of sweat provides by far the greatest potential for heat loss and it represents the only means of heat loss when air temperature exceeds skin temperature. Sweat production results from the integration of afferent neural information from peripheral and central ...

The problem of temperature regulation is most acute for the astronaut when he is outside his vehicle and therefore disconnected from the relatively bulky machinery which normally attends to his thermal needs. It is necessary to arrange that metabolic heat is transported from the skin surface to some device which will absorb it.

Heat loss in the newborn infant
The Indian Journal of Pediatrics, 1971On the basis of our investigations in which for the first time the insensible water loss was measured directly in newborn infants during the first 24 hours of life, the magnitude of the heat loss from the total heat production due to evaporation of water was calculated.

The thermal environment affects humans and the temperature patterns on their skin surface through the transfer processes between their bodies and surroundings. The physical processes involved are basically the same both outdoors and indoors but their relative magnitude is dependent on the conditions.

Abstract This chapter covers intraoperative heat loss mechanisms leading to hypothermia. Hypothermia is an important physiologic mechanism with many perioperative risks affecting both morbidity and mortality. Identifying potential sources of heat loss, specifically related to anesthetic techniques and the environment, is integral to the ...

Under hot conditions the amount of heat that can be lost through sensible channels is limited. Moreover, when the dry bulb temperature and the radiant temperature are above body temperature there is a net gain of heat. Evaporative heat loss therefore becomes progressively more important for the maintenance of body temperature as the ambient temperature

It has been shown in a previous chapter that the value of skin temperature at a given point is the result of an equilibrium between heat received from the body core, mainly via the blood, and heat lost into the environment. In turn, skin temperature is one of the most important factors determining the transfer of detectable heat.
