Simulator systems for teaching patient care are provided. In some instances, the simulator system includes a master computer module positioned within a patient body and configured to communicate simulation commands to a pneumatic module also positioned within the patient body and spaced from the master computer module. A compressor module is configured to control a compressor to supply compressed air from the compressor to the pneumatic module. The pneumatic module includes a processor configured to execute the simulation commands received from the master computer module to control a physically simulated body part of the patient body with the supplied compressed air.
