Sensitivity of the Heat and Mass Transport System Within Neonate Clothing

Abstract

The global model of heat and mass transport is determined by means of the heat balance with a term describing evaporation of sweat. Heat is supplied by metabolic heat production and lost by means of different phenomena within all body portions. The global correlation can be solved for prescribed parameters of the bonnet and external clothing. Different clothing materials, covering area and thickness of the bonnet, as well as characteristic times are discussed to prevent hyperthermia and hypothermia.

Investigations of Three‐Layer Systems Intended for Protective Clothing for Prematurely Born Babies

“…Consequently, the body temperature will be decreased and the body will be subjected to hypothermia. [ 7 ]…”

“…It can be a garment made of foil that completely blocks the transport of moisture from the baby's skin to the outside, or it can be a knitted baby garment that provides thermal protection with an additional layer of foil intended to block moisture transport. [ 7 ]…”

“…It can be a garment made of foil that completely blocks the transport of moisture from the baby's skin to the outside, or it can be a knitted baby garment that provides thermal protection with an additional layer of foil intended to block moisture transport. [7] Nowadays, premature babies after their birth are instantly dressed in a polyethylene Calorkeeper bag from VYGON, which prevents babies from transdermal moisture loss. There is an urgent requirement to develop clothing technology for premature infants that simultaneously maintains thermal balance and fluid mass from the body in physiological equilibrium.…”

“…Consequently, the body temperature will be decreased and the body will be subjected to hypothermia. [7] Hypothermia in newborns, regardless of gestational age, is defined as an infant's body temperature below 36.5 °C. However, the appropriate body temperature is not sufficient to determine whether the thermal environment in which the baby is located is optimal due to the fact that premature infants may exhibit clinical signs of cold stress.…”
