GE Datex Ohmeda 4400 Infant Warmer System

  • GE Datex Ohmeda 4400 Infant Warmer System

The GE Ohmeda 4400 Infant Warmer System uses a manual mode of operation that allows selection of the level of radiant heat output as indicated by the % power display on the control panel and the control circuit then maintains the selected level of radiant heat. Servo mode of operation allows selection of the patient’s control temperature and a control system modulates the radiant heat to maintain the patient at the selected control temperature. Alarms activate to alert the operator of a low or high patient temperature, a skin temperature probe failure, a power failure, equipment failure or a check patient prompt.

Heater Assembly

  • The radiant heater provides a focused heat source using a cal-rod heating element, which directs controlled heat to the bed surface.
  • The heater assembly, located above the center of the bed, consists of the radiant heater, parabolic reflector, integral observation light, and visible red alarm indicator light.
  • The heater module rotates 90 degrees to the side to facilitate X-ray procedures.
  • The heater automatically shuts off when in this position.


  • The hydraulic tilt system provides tilt of up to +10o for positioning in Trendelenburg and reverse Trendelenburg positions.
  • The four bedside panels fold down for complete access to the infant.
  • The rear panel includes tubing management slots for the retention of ventilation and aerosol tubing.
  • The bed incorporates an X-ray Cassette Tray.
  • A grid location marking system on the side panels matches the tray for the location of the cassette.
  • Bed construction is radiolucent.
  • A chest drainage hanger allows for the convenient placement of chest drainage systems.
