Effect of Different Signal Processing Techniques on a Calibration Free Pulse Oximeter

A pulse oximeter is a medical device that measures pulse rate and oxygen saturation levels of a person non-invasively. Monitoring of health parameters of a patient requires a device that gives accurate results in all conditions and is not affected by artifacts arising from environmental and physiological factors. One of the noise factors we focus in this paper is motion artifacts. These artifacts affect the quality of signal acquired by the...
