Circulatory response to heat loss
WebHypothermic infants should be rewarmed, and any underlying condition must be diagnosed and treated. Normal rectal temperature in term and preterm infants is 36.5 to 37.5° C. Although hypothermia is a core temperature < 36.5° C, there may be cold stress at higher temperatures whenever heat loss requires an increase in metabolic heat production.

Heat loss occurs primarily from the skin of a patient to the environment through several processes, including radiation, conduction and convection, and evaporation. 2 Of these, radiation is most significant and accounts for ∼60% of total heat loss. Radiation is emitted in the form of infrared rays, a type of electromagnetic wave.

The body uses more energy … WebApr 1, 2016 · Upon cold exposure, the initial physiological response is a peripheral skin vasoconstriction and a reduction in skin blood flow. This reduces convective heat transfer between the body's core and shell (skin, subcutaneous fat, and skeletal muscle), effectively increasing insulation by the body's shell.
