A radiant warmer is a medical device that uses overhead heat to help keep a newborn or infant warm. It creates an open care area so clinicians can reach the baby while providing thermal support. Radiant warmers are often used in delivery rooms, neonatal units, and procedure areas. They are designed for infants who need help maintaining body temperature.
read more about radiant warmer ...A radiant warmer is used to reduce heat loss in newborns, especially premature, sick, or newly delivered infants. It can help during resuscitation, examination, line placement, procedures, or observation. The open design gives clinicians access to the baby without removing the heat source. It is used with temperature monitoring so warming can be adjusted to the infant’s needs.
The warmer sends infrared heat from an overhead heating element toward the infant. Some systems use a skin temperature probe and servo control to adjust heat output based on the baby’s measured temperature. Other settings require manual adjustment by trained staff. The goal is to keep the infant warm without overheating.
The baby is placed on the warmer bed under the heating element. Staff position the infant, attach temperature monitoring when ordered, and set the warming mode according to the care plan. The baby’s temperature, skin condition, breathing, and overall status are checked during use. Access to the airway, monitors, lines, and equipment is kept clear.
Radiant warmers require close monitoring because infants can lose heat quickly or become overheated. Risks include dehydration, burns, overheating, cold stress, or temperature swings if settings or probes are wrong. The skin probe should be placed securely when servo mode is used. Changes in color, breathing, temperature, activity, or skin condition should be addressed promptly by the care team.
No. A radiant warmer provides overhead heat in an open bed, while an incubator encloses the infant in a controlled environment.
Newborns can lose heat quickly after birth. A radiant warmer helps maintain temperature while clinicians assess, treat, or monitor the baby.
Yes. That is why temperature probes, correct settings, and frequent monitoring are needed during use.
No. They are often used for premature infants, but full-term newborns may also need warming during delivery-room care, procedures, or illness.
