A pressure cuff detection system comprising an air compressor in communication with a pressurised air distributor having a plurality of pressurised air outlets, one or more of said outlets being in pressurised air communication with one type of pressure cuff selected from a group of possible such cuffs, each pressurised air outlet coupled to its own valve means adapted to open and close the outlets, control means provided to monitor, in use, pressure variation at said ports and thereby determine which ports are open and which are closed, and to identify from such determination the particular type of cuff actually connected to the port(s).
