Considering Cardinality in a Medical Device PnP System

In designing systems of hardware and software, we get more leverage from decisions about cardinality than almost any other choices. When we study an existing system, the fundamental insight we gain is an understanding of the cardinalities of the system. From the cardinalities we can choose (or infer) the basic operation and prioritization of the system, without being distracted by details. This paper will briefly explore some of the cardinality-sensitive attributes of medical device plug and play systems.
