Other methods of simulating human lungs Ventilator test lung and trigger assembly

CA 2699661 A1 Uses a rigid container with fixed walls Series of valves control resistance to flow Pneumatic trigger (actuated by vacuum generator) housed

inside of rigid container Servo lung simulator and related control method

WO 1997012351 A1 Uses a computer controlled piston to reproduce lung behavior. Volume is measured through piston displacement accurate to 50

μL.  Since the model is mathematical and implemented in software,

an infinite variety of resistance and compliance values can be chosen by the user.
