What is the primary function of a Radiant Warmer?

• A. Enclosed apparatus providing controlled heat and O2 for premature babies
• B. Device that scans body temperature wirelessly
• C. Device used to measure blood pressure
• D. Surgical imaging device

Answer: (A)

The main idea here is that a radiant warmer is used to keep newborns, especially premature babies, at a stable and warm body temperature. Premature infants have a hard time regulating their temperature, so providing steady heat helps conserve energy for growth and metabolism and reduces stress on their little bodies. Radiant warmers deliver heat using infrared radiation, allowing caregivers to access the baby for care while still maintaining warmth. Some units can also provide supplemental oxygen as part of supporting the infant’s breathing, but heat support is the core purpose. The other devices described—scanning temperature wirelessly, measuring blood pressure, or providing surgical imaging—serve entirely different clinical roles, not warming the baby.
