What is a servo cradle and its functions?

A servo cradle is a medical equipment frequently used in neonatal intensive care units, whose purpose is to provide newborns with a comfortable thermal area that allows them to maintain their body temperature within normal levels.

They are extremely essential equipment because when a baby is born, it needs to be heated, so that its temperature does not fluctuate considerably since its natural incubator was previously inside the mother’s womb. That is why at birth, care should be taken to maintain the baby’s body temperature at normal levels, since they are very susceptible to hypothermia, which leads to the deterioration of their bodily and organic functions.

Functions of a servo cradles

Servo cradles are equipment frequently used in delivery rooms and neonatal care units with the aim of providing external warmth and open access to newborns. In this equipment, heat transfer is carried out mainly by thermal radiation; that is, the source of heat energy is separated from the heat receiver and the latter (heat) travels through the air in the form of electromagnetic waves.

In which patients are servo cradles used?

Once birth occurs, newborns are routinely placed under warm, radiant light to help stabilize their temperature until they can achieve self-regulation. They are also necessary for critically ill patients who require constant nursing care.

A servocraled is a high-risk medical equipment that can endanger the life of the newborn. Therefore, it is recommended to use the equipment only in the operating room, neonatal nursery, pediatric intensive care unit in a hospital. The person who will handle the equipment must be specially trained and operate only under the instruction given by the doctor.

And it should be borne in mind that the flow of hot air can affect the thermal balance of the newborn. Therefore, the cradle should be placed in a room where the airflow is less than 0.3m/sec.

Structure of a servo cradle

A servo-cradle is a heating unit, made up of a heat source, a skin temperature sensor, a servo-control unit, and visual and audible alarms.

The heat source (heating element) generates radiant energy in the far IR wavelength region, but is limited to prevent thermal damage to the newborn. Infrared energy is easily absorbed by the newborn’s fragile skin, increasing blood flow to the skin and then transferring heat to the rest of the baby’s body by blood convection and tissue conduction.
