GE Ohmeda 4400 IWS Features

The GE Ohmeda 4400 Infant Warmer System uses a manual mode of operation that allows the 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. The servo mode of operation allows the 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, an 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

Bed

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 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 convenient placement of chest drainage systems

General Information About Infant Warmers

What is an infant warmer?

Newborn infants can lose a tremendous amount of body heat during birth and the first few hours of life
Infant warmers are devices that prevent this loss
Also called Overhead Radiant Warmers

Physiology

Have overhead electrical heating elements that emit infrared rays, usually focused down to a small area where the infant is placed
Overhead unit provides a warm environment while allowing for direct observation and free access to the infant unlike in Incubators
Delivery rooms, infant care nurseries, admission, and infant surgical areas are some places where warmers are used
Insensible water loss is greatly increased with the use of warmer
Infrared rays are an excellent source of heat and are greatly absorbed by the surface of the skin – peripheral blood is heated
Heat is transferred to deeper tissues by conduction and by circulating blood

Working with infant Warmers

Warmer is provided with a heating element for directing radiant heat onto an infant support surface and a temperature sensing probe attachable to the skin of an infant
Automatic mode: when the actual temperature reaches the set temperature value, the control signal cuts off the heater output and thereby regulates temperature
The control also operates to reduce the power to the heater when the total energy supplied to the heater exceeds a maximum amount over a predetermined time interval
Manual mode: the power level is reduced when a preset temperature is reached or if the temperature is not reached after a predetermined time has elapsed
In addition, the heater power is interrupted whenever the control signal or the current to the heater exists independent of the other
