Thesis on Pulse Oximeter Calibrator

Pulse Oximeters are standard medical electronics devices used for continuous patient monitoring of arterial oxygen saturation (SpO2) and heart rate (HR). Initial calibration of pulse oximeters is conducted by inducing hypoxemia in healthy human volunteers to obtain blood oxygenation levels as low as 70% and comparing pulse oximeter measurements to that of a reference CO-oximeter.

It was the goal of this project to create a device which would increase the accuracy of the calibration process and potentially set the stage for the elimination of the need for human volunteers. Such a device would also significantly reduce cost and time for companies attempting to bring a new model of pulse oximeter to market. A device such as this, even if it is not used as a substitute for testing on humans, would allow the company the opportunity to test their device before making the expensive commitments involved with FDA testing.
