An integrated pulse oximeter system for telemedicine applications

This paper will describe a wireless integrated pulse oximeter system that enables the measurement of blood oxygen saturation and the direct measurement of heart rate. Its implementation is relatively simple and thus easily put on a VLSI chip so it can be attached on a person's ear lobe, finger or other body part. The chip includes a radio transmitter/telemetry system, so measurement data can be linked to a data acquisition system. To conserve battery life, the sensor will be activated by external RF tagging as needed.
