A care delivery system includes a bed (20) having a bed-side interface unit (B), an appliance set (90) comprising one or more appliances (99) and two or more appliance-side interface units (A) distributed among the appliances, and a set (124) of one or more adaptors (126) each having a host interface unit (H) compatible with the bed-side interface unit, and a client interface unit (C). Each adaptor is arranged to accommodate fluid flow between its host interface unit and its client interface unit. Each client interface unit of the adaptor set, taken individually, is compatible with at least one but fewer than all of the appliance-side interface units of the appliance set and, taken collectively, are compatible with all of the appliance-side interface units of the appliance set. The system also includes an appliance annunciator (140) and an appliance discriminator (76) responsive to the annunciator thereby configuring the system for the pneumatic demands of the appliance.
