How does the temperature and heartbeat control works in baby incubator?

how those devices work in a baby incubator?How does the temperature and heartbeat control works in baby incubator?
I have no idea about baby incubators, but I remember when my son had been in a motorcycle wreck and was in a coma for about six weeks, his brain stem was unable to regulate his body temperature. Part of his care was a plastic pad with channels where water was pumped through. There was a thermostat and a connection to his body for a thermometer. If his body was hot, cold water was pumped through the plastic pad to cool him. If he got too cool, hot water was pumped through the pad to warm him.


Baby incubators also provide a high percentage of oxygen to a baby, and can increase atmospheric pressure to help a baby breathe, sort of like an ';iron lung'; used for polio patients in the fifties.


My grandson was a preemie, and he had a device that gave his heart a boost, sort of like a mini difibrillator. You have probably seen defibrillators on TV shows, where the doctor puts two paddles on the chest, and the patient's body jerks from the electrical stimulus. Baby defibrillators have the pads in a band around their bodies, and their heartbeat is monitored, and restarted if it stops.
