Abstract

A multiple patient infant warming management system comprises at least one temperature sensor for sensing at least one temperature of an infant warming device and a controller. The controller processes first signals for different temperature ranges of different temperature zones assigned to different patients to be concurrently warmed the infant warming device, receives second signals from the at least one temperature sensor indicating at least one temperature of the infant warming device and outputs adjustments based on the first signals and the second signals.
