1. A patient monitoring device capable of configuring itself for differing operational conditions comprising:
- a physiological signal input configured to receive a physiological signal from a noninvasive optical sensor, said physiological signal indicative of one or more physiological parameters of a patient being monitored;
a signal processing device configured to process said physiological signal and to determine values of said one or more physiological parameters, said processing of said physiological signal including accessing a plurality of configurable processing parameters, at least some of said configurable processing parameters affecting a sensitivity of said processing to changes in said physiological signal; and
a caregiver-actuated emergency care input, wherein actuation of said caregiver-actuated emergency care input electronically adjusts one or more of said at least some configurable processing parameters to increase said sensitivity for emergency care situations.

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.
