DESIGN & IMPLEMENTATION OF PULSEOXYMETER TO MEASURES THE OXYGEN SATURATION IN BLOOD

Abstract

Present paper deals with problem statement to develop a system which measures the oxygen saturation in the blood, so that we can incorporate this vital signal in our clinical diagnostic system. This signal is important to monitor the oxygen exchange in the lungs which indicates how well the arterial blood is oxygenated. Poor exchange may indicate respiratory failure. It has been realized that this information can be available via the non-invasive technique of pulse oxymetry, which is now a well-established technique in clinical settings. Both the theoretical principles and methodology of solution are presented in this paper.
