A lung-simulator system that mimics spontaneous respiration.
Conventional test lungs and commercial lung simulators have the capacity for varying compliance and resistance, but none generates reproducible spontaneous respiratory efforts. The lung simulator described here, used with a variable-flow, piston-driven ventilator, can simulate and reproduce spontaneous respiratory effort. It may be useful in education, clinical management, and preventive maintenance.
