1. A patient monitoring device configurable for differing operational conditions, said device 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, the patient monitoring device being configurable to operate in a first configuration and a second configuration, wherein said sensitivity is greater in the second configuration than in the first configuration; and

    a single caregiver-actuated emergency care input that, when actuated a single time, causes the patient monitoring device to operate in the second configuration and electronically adjusts a plurality of said at least some configurable processing parameters to increase said sensitivity for emergency care situations.
