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;

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

    determine that the measurement of the physiological parameter satisfies an alarm activation threshold;

    receive, from a user, an indication ofinitiate a parameter-specific alarm delay or suspension period of time corresponding to the physiological parameter, the parameter-specific alarm delay or suspension period of time being selected fromone of a plurality of parameter-specific alarm delay or suspension periods of time, the parameter-specific alarm delay or suspension period of time being different from at least one other parameter-specific alarm delay or 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;

    andin response to receiving the alarm suspension indication, suspend the alarm foractivate an alarm for the physiological parameter in response to expiration of an amount of delay or suspension associated with the indicated parameter-specific alarm delay or suspension period of time.
