A feedback controller for supplemental oxygen treatment of newborn infants: a simulation study

Abstract

A microcomputer control system has been developed for supplemental oxygen therapy of newborn infants. The system uses feedback of arterial oxygen saturation to adjust the concentration of oxygen in the incubator or under the hood. The control system has been tested under different physiological conditions, using a detailed simulation model of the neonatal respiratory system. Some of the simulation results of this study are presented to illustrate the performance of the controller.
