ABSTRACT:
A pneumatic lung analog for simulating spontaneous breathing and for testing of ventilatory devices used with spontaneously breathing patients and a kit for modifying training test lungs for this purpose is provided. The lung analog comprises a frame, a test ventilator, or lung simulator, expansible chamber; and a spontaneous breath expansible chamber disposed on the frame for receiving the output of a ventilatory device and a spontaneous breath generator, respectively. A movable end plate is disposed on the lung simulator and spontaneous breath expansible chambers for concurrent movement therewith when the spontaneous breath expansible chamber is inflated. Transducers are provided for measuring the airway pressure and the volume of air supplied to the lung simulator chamber by the ventilator being tested for determining the performance characteristics of the ventilator, such as the added work of breathing attributable to the ventilator.
