1. A system for monitoring parameters of a medical patient using signals received from physiological sensors associated with the medical patient, the system comprising:

  • a memory device configured to store an alarm delay time and an alarm threshold;

    a hardware processor in communication with the memory device, the hardware processor configured to;

    monitor a physiological parameter reflecting physiological information obtained from a physiological sensor coupled to a medical patient, anddetermine whether the physiological parameter satisfies the alarm threshold for an amount of time corresponding to the alarm delay time;

    a visible alarm or an audible alarm configured to be triggered in response to determining that the physiological parameter satisfies the alarm threshold for the amount of time corresponding to the alarm delay time; and

    a display configured to output an indicator responsive to an amount of time that the physiological parameter satisfies the alarm threshold,wherein the indicator is a visible indicator that is responsive to a comparison of (i) the amount of time that the physiological parameter satisfies the alarm threshold and (ii) the alarm delay time, andwherein the visible indicator comprises (i) a count that depends on the comparison, (ii) a first alert having a display frequency that depends on the comparison, or (iii) a second alert having a display size that depends on the comparison.
