1. A system configured to provide synchronized screen content, the system comprising:

  • a server; and

    a plurality of infusion pumps configured to deliver medications to one or more patients and in network communication with the server, wherein each respective infusion pump of the plurality of infusion pumps comprises (i) a display configured to display one or more metrics of a plurality of metrics maintained by the respective infusion pump and (ii) a memory configured to store internal clock data usable to determine a current time associated with the respective networked device, wherein the respective infusion pump is configured to;

    receive a clock synchronization data from the server, wherein the clock synchronization data is indicative of a reference time associated with the server;

    update the internal clock data based on the clock synchronization data;

    receive metric display data from the server, wherein the metric display data comprises a metric display period and an indication of two or more metrics to be displayed on the display of the respective networked device;

    based on a determination that a user input has not been received for a threshold amount of time, determine a first current time associated with the internal clock data;

    calculate a first metric index based on the first current time, the metric display period, and the indication of the two or more metrics received from the server;

    determine a first metric of the plurality of metrics that is associated with the first metric index;

    cause the first metric to be displayed on the display of the respective infusion pump at a first time;

    within at least the metric display period from the first time, determine a second current time associated with the internal clock data;

    calculate a second metric index based on the second current time, the metric display period, and the indication of the two or more metrics received from the server;

    determine a second metric of the plurality of metrics that is associated with the second metric index; and

    cause the first metric displayed on the display of the respective infusion pump to be replaced with the second metric at a second time that is not later than the first time by a time period equal to the metric display period.
