Oxygen CONTROL AND STABILIZATION Study Program
Executive Summary
Executive Summary
The intent of this program is to study the effects of an automatic system of oxygen control of the levels of oxygen in a premature baby. The present system of neonatal oxygen control depends on the full time monitoring of oxygen level by a health care professional with variation controlled manually. The proposed study will use a “breadboard” system made up of a pulse oxymeter (to measure oxygen level), a digitally controlled valve (to vary oxygen supply), and a computer (to control the overall process). A software program has been developed to optimize the delivery of oxygen and control the system. In addition, a software model has been developed to predict the results. Data will be compiled to determine the accuracy of the predictive capability of the model.
I. Technical Summary
Describe system and benefits
The breadboard system is made up of a Masimo Pulse Oxymeter, an oxygen control valve which was modified to respond to digital control signals from a computer, and a desk top computer running a program which was developed in Lab View. The program monitors a digital interface with the oxymeter to obtain the oxygen blood level readings of the baby. The program then uses a set of limits set by the physician to determine whether the measured level is within the desired range. If it is and the program determines that the measured level is relatively stable, no correction will be made. If one of the criteria is not met, the computer will command a correction of the level to the
