Development of an artificial vital sign generator for pulse oximeter.

This paper presents an artificial vital sign generator that enables medical trainees to measure SpO(2) and the pulse rate of a patient simulator using a pulse oximeter. The proposed system has a biological model that possesses a structure that is the inverse of a pulse oximeter probe, and it works using the inverse procedure to that of pulse oximetry. The SpO(2) generating function has been validated using two commercially available pulse oximeters.
