1. A physiological measurement system comprising:

  • a noninvasive physiological sensor including;

    a plurality of light emitting diodes configured to transmit wavelengths of light onto a tissue site of a patient; and

    at least one detector configured to measure an indication of the wavelengths of light after attenuation by tissue of the patient and be positioned on a patient and output a signal responsive of the attenuated light to a physiological condition of the patient; and

    one or more processors in communication with the noninvasive physiological sensor, the one or more processors configured to electronically;

    process the signal to determine a measurement of a physiological parameter based at least in part upon the signal;

    determine that an alarm should be activated in response to the measurement of the physiological parameter satisfying an alarm activation threshold;

    receive, from a user,determine that an indication ofalarm suspension should be initiated for a parameter-specific alarm suspension period of time corresponding to the physiological parameter, the parameter-specific alarm suspension period of time being selected fromone of at least a plurality of parameter-specific alarm suspension periods of time, the parameter-specific alarm suspension period of time being different from at least one other parameter-specific alarm suspension period of time corresponding to at least one other physiological parameter for which the one or more processors are configured to determine at least one measurement;

    activate an alarm in response to determining that an alarm activation threshold has been satisfied by the physiological parameter measurement;

    receive an alarm suspension indication; and

    in response to receiving the alarm suspension indication,suspend the alarm for the indicated parameter-specific alarm suspension period of time; and

    activate the alarm when the measurement of the physiological parameter satisfies the alarm activation threshold after the parameter-specific alarm suspension period of time has passed.
