1. A system for managing alarm notifications, the system comprising:

  • a patient monitor comprising memory, a display, a port that connects with a physiological sensor configured to be coupled with a patient, and a processor that processes input from the physiological sensor to compute physiological parameter values for output on the display;

    an optical scanner configured to be in communication with the patient monitor optionally through a cable, the optical scanner operable to scan machine-readable codes when the optical scanner is in use;

    the memory of the patient monitor programmed with instructions configured to be executed by the processor to;

    receive a first optical scan of a first identification tag from the optical scanner, the first identification tag comprising a first machine-readable code on a patient bracelet;

    receive a second optical scan of a second identification tag from the optical scanner, the second identification tag comprising a second machine-readable code on the patient monitor;

    obtain a first identifier associated with the patient from the first optical scan;

    obtain a second identifier associated with the patient monitor or location from the second optical scan;

    associate the first identifier with the second identifier in physical computer storage so as to admit the patient to the patient monitor and to store a location of the patient in the physical computer storage;

    output an admit user interface comprising functionality for a user to assign a first clinician to a primary assignment for the patient and for the user to assign a second clinician to a secondary assignment for the patient;

    determine that the physiological parameter values trigger an alarm; and

    send an alarm indication responsive to the determination that the physiological parameter values trigger an alarm; and

    a multi-patient monitoring computing device configured to;

    responsive to receiving the alarm indication, send an alarm notification message to a clinician device associated with the first clinician, wherein the alarm notification message comprises the first identifier, the second identifier, and an indication of the location of the patient;

    determine whether a first indication that the alarm notification message was received by the clinician device has been received from the clinician device;

    in response to not receiving, from the clinician device, the first indication, accelerate escalation of the alarm;

    in response to receiving, from the clinician device, the first indication;

    determine whether a second indication that the alarm notification message was viewed by the clinician user at the clinician device has been received from the clinician device, wherein the second indication indicates that the clinician user has viewed but not yet responded to the alarm notification message;

    in response to not receiving, from the clinician device, the second indication, accelerate escalation of the alarm; and

    in response to receiving, from the clinician device, the second indication;

    determine whether a response responsive to a user input, provided by the clinician user at the clinician device, indicating that the clinician user has declined handling the alarm has been received from the clinician device;

    in response to receiving, from the clinician device, the response responsive to the user input, accelerate escalation of the alarm; and

    in response to not receiving, from the clinician device, the response responsive to the user input;



    determine whether the alarm has been cleared; and



    in response to determining that the alarm has not been cleared, accelerate escalation of the alarm;

    determine whether or not an escalation condition is present based at least in part on at least one of;

    receipt or non-receipt of the first indication from the clinician device, receipt or non-receipt of the second indication from the clinician device, or receipt or non-receipt of the response from the clinician device; and

    in response to determining that the escalation condition is present, automatically escalate the alarm by sending the alarm notification message to a second clinician device associated with the second clinician.
