Abstract: An application identification sensor comprises a plurality of emitters configured to transmit light into a tissue site and a detector configured to receive the light after tissue absorption. The detector generates a signal responsive to the intensity of the light and communicates the signal to a monitor. An information element is readable by the monitor so as to identify a sensor application. The monitor presets at least one user-selectable operational parameter in response to the information element.
