1. A medical device monitoring system comprising:
a server having one or more processors configured to:
receive, via a computer network, from at least one medical device controller of a plurality of medical device controllers, at least one image of contents displayed on a screen of the at least one medical device controller;
send a request to an optical character recognition (OCR) engine to extract textual information from at least a portion of the at least one image;
receive, from the OCR engine, extracted textual information; and
send, in response to at least two trigger conditions of a plurality of trigger conditions being met, a request to the at least one medical device controller to change a first rate at which the at least one medical device controller sends images to the server to a second rate, the first and second rates being non-zero,
wherein the plurality of trigger conditions comprises:
a first condition based on whether the extracted textual information comprises alarm text;
a second condition based on whether the extracted textual information comprises an indication that a medical device is connected to the at least one medical device controller; or
a third condition based on the results of a validation test performed on the extracted textual information,
wherein each one of the plurality of trigger conditions is specific to at least one of a plurality of predetermined rates at which the at least one medical device controller sends images to the server,
wherein two or more of the plurality of trigger conditions are specific to different ones of the plurality of predetermined rates, and
wherein the second rate is selected by the one or more processors in response to a determination that the second rate is the fastest or the slowest of the predetermined rates specific to one or more of the at least two trigger conditions.
