Health problem addressedThese devices are commonly used to provide thermal

support for newborns in the delivery suite, for critically ill

infants who require constant nursing intervention, and for

infants undergoing treatment that prolongs exposure to a

cool environment. Prolonged cold stress can overwork heat-

producing mechanisms, drain energy reserves, and result in

hypoxia, acidosis, hypoglycemia, and, in severe cases, death.

Product descriptionInfant radiant warmers are overhead heating units. They typically

consist of a heat source, a skin-temperature sensor, an automatic

(servo) control unit, and visual and audible alarms.

Principles of operationA heating element generates a signifi cant amount of radiant

energy in the far IR wavelength region (longer than three microns

to avoid damaging the infant’s retina and cornea). The radiant

output of the heating unit is also limited to prevent thermal

damage to the infant. The IR energy is readily absorbed by the

infant’s skin; increased blood fl ow in the skin then transfers heat

to the rest of the body by blood convection (heat exchange

between the blood and tissue surfaces) and tissue conduction

(heat transfer between adjacent tissue surfaces).

Operating stepsAfter birth, infants are placed under a radiant warmer until they

can achieve thermoregulation.

Reported problemsBecause warming by IR energy is an effi cient means of energy

transfer, extreme hyperthermia, skin burns, permanent brain

damage, or even death can result.
