1. A physiological measurement system comprising:

  • a 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 output a signal responsive of the attenuated light;

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

    determine a measurement of a physiological parameter based on the signal;

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

    in response to a silence request by a user, suspend the alarm for a parameter-specific period of time; and

    before expiration of the parameter-specific period of time, and in response to determining the physiological parameter measurement no longer satisfies the alarm activation threshold, deactivate the suspended alarm.
