Abstract:
1. A pulse oximeter for measuring arterial oxygen saturation levels comprising: an LED signal generator for transmitting one or more light signals to a testing medium when a turn on voltage is applied to the LED signal generator; a photodetector signal generator for obtaining at least a portion of the light signal generated by the LED signal generator and for generating a photocurrent corresponding to the detected signals; an integrated information transmission component for storing information corresponding to the pulse oximeter and for transmitting the information; and an oximeter processing system for applying a turn on voltage to the LED signal generator to cause the LED signal generator to generate a signal, for processing the photocurrent from the photodetector signal generator and for providing a voltage source to cause the information transmission component to transmit the stored information corresponding to the pulse oximeter; wherein the voltage of the voltage source provided by the oximeter processing system to cause the information transmission component to transmit the stored information is higher than the turn on voltage of the LED signal generator and is applied to the information transmission component without causing the LED signal generator to generate a signal.
