Abstract: Techniques for managing encoded communications for medical devices in a clinical environment are provided. Different versions of signal coding libraries are generated for different devices in a communication path. A first signal coding library may be generated using a first signal definition that includes a set of fields. A second signal coding library may be generated using a second signal definition that includes a subset of the fields of the first signal definition, and excludes one or more of the fields of the first signal definition. A message encoded using the first signal coding library may not be completely decodable using the second signal coding library. By selectively deploying the signal coding libraries to different systems, devices, and components in a clinical environment, access to information in message fields can be effectively managed.
