Study Notes
Neonatal Incubator
- A rigid box-like enclosure for keeping an infant in a controlled environment for observation and care
- Includes features such as:
- Heater
- Fan
- Container for water to add humidity
- Control valve for adding oxygen
- Access ports for nursing care
Uses of Neonatal Incubator
- For neonates, especially those with low birth weight, born prematurely, or with medical conditions
- For infants with breathing difficulties
- For treating jaundice using phototherapy (light sources with wavelength 360 nm)
Operation Principle
- Infant lies on a mattress in the infant compartment, enclosed by a clear plastic hood
- Hand access ports with doors allow handling of the infant while limiting cool room air introduction
- Clinician can raise or remove the plastic hood or open a panel for greater access
- Some units have an air curtain that sweeps warm air past the opening
Heating and Humidification Systems
- Heating system warms the infant by forced or natural flow of heated air
- Some units use convective airflow, while others use actively warming incubator walls to reduce radiant heat loss
- Another unit uses a mattress of warm water to warm the infant
- Heating and humidification systems are located beneath the infant compartment
- Fan or natural flow circulates air past the heater and temperature-measuring device, over a water reservoir for humidification, and up into the infant compartment
Modes of Operation
Air-Temperature Control
- Operator sets the temperature of the air in the incubator
- Changes in infant body temperature are usually measured periodically with a thermometer, and adjustments in air temperature are made accordingly
Skin-Temperature Control (Servo Mode)
- Sensor is taped to the infant's skin, and the heater responds to changes in the sensor to keep the skin temperature at the preset level
