Abstract :
A control system is proposed for oxygen therapy of premature infants. The control software consists of a stepwise as well as a PID control algorithm to provide fast and efficient response to changes in arterial oxygen saturation of the infant detected by pulse oximetry. The control system is tested by using a simulation model of the infant´s respiratory system. The simulation results at different levels of hypoxia are evaluated and the robustness of the controller is assessed.
