Claim One:
1. A method of operating an assembly of a breathing-assist device and a simulating device comprising the steps of: in said simulation device, generating a simulated bioelectrical signal related to breathing by a respiratory subject; supplying said simulated bioelectrical signal from the simulation device to the breathing-assist device; controlling operation of the breathing-assist device to produce breathing assistance, which otherwise occurs in response to an actual bioelectrical signal obtained from a patient, dependent on the simulated bioelectrical signal related to breathing by a respiratory subject, in a same manner as occurs in dependence of said actual bioelectrical signal and generating a feedback signal in said breathing-assist device that is indicative of said breathing assistance; and providing said feedback signal from the breathing-assist device to the simulation device and, in the simulation device, adjusting the simulated signal in response to the feedback signal.
