1. A system for providing patient monitoring data over a network, the system comprising:

  • a medical edge router having one or more hardware processors, the medical edge router comprising;

    a plurality of inputs in communication with a plurality of point of care devices;

    a plurality of wired outputs in communication with a plurality of wired routers or switches associated with first and second Internet service providers (ISPs);

    a traffic inspector configured to;

    receive input packets from the plurality of point of care devices, the input packets comprising information related to patient monitoring data, the information related to patient monitoring data comprising physiological parameter values, trend data representing trends in the physiological parameter values, and patient monitoring alarms representing the physiological parameter values reaching alarm limits, andanalyze the input packets to identify the patient monitoring alarms in the input packets; and

    a routing module comprising routing tables populated with routing information generated according to a Border Gateway Protocol, the routing module configured to;

    update the routing tables over time using the Border Gateway Protocol;

    receive an indication from the traffic inspector that the patient monitoring alarms are contained in some of the input packets;

    in response to receiving the indication, route first ones of the input packets that do not correspond to the patient monitoring alarms over a first communications channel corresponding to the first ISP and route second ones of the input packets over a second communications channel corresponding to at least the second ISP in response to detecting the patient monitoring alarms in the second input packets;

    in response to determining that the first and second communications channels are unavailable, route a reduced form of the input data over a third communications channel having lower second bandwidth than a first bandwidth of the first and second channel by;

    prioritizing the patient monitoring alarms over the physiological parameter values, such that the patient monitoring alarms are transmitted over the third communications channel instead of the physiological parameter values based on the second bandwidth, andprioritizing the physiological parameter values over the trend data which consumes greater bandwidth than the physiological parameter values, such that the physiological parameter values are transmitted over the third communications channel instead of the trend data based on the second bandwidth.
