Abstract

A perfusion system apparatus includes a subject simulator for simulating a subject. The subject simulator includes a circulatory system having an inlet line for receiving fluid from the perfusion system, an outlet line for transferring fluid to the perfusion system, at least one sensor for sensing at least one fluid property and at least one control device coupled to at least one of the inlet line and the outlet line. The control device manipulates the at least on fluid property based at least partially on signals from the at least one sensor, to thereby simulate a least one of compliance and resistance of the simulated subject.
