Physical Environment: the Thermal Environment

摘要: During intrauterine life, heat production by the fetus results in a fetal temperature that is about 0.5°C higher than maternal [1]. After birth, newborn infant exposed to air and surfaces, which have much lower previously experienced utero. The skin surface at birth covered with amniotic fluid, causing loss through evaporation an environment low vapor pressure [2]. As result body of lowered, rate this reduction influenced environmental delivery room its flow. This gives rise thermogenic responses increase basal [1, 3] circulation may decrease losses [4].
