Patent number: 11291767Abstract: It may desirable to monitor or control a pump remotely. For example, the pump may be positioned near the patient, with remote control or monitoring of the pump occurring in a control room. In one exemplary embodiment, the pump is used in an MRI environment. In another exemplary embodiment, the pump is used in a hyperbaric chamber. The pump may monitor one or more physiological parameters and transmit them to the remote. The pump may also transmit information relating to the pump's operation. The pump may send the device and/or physiological data using one or more packets. The packets may consist of low priority sequential packets and high-priority asynchronous packets.
