Simulation of lung ventilation using a model lung can provide a means of evaluating lung function tests, mathematical models and computer algorithms. We describe a new water-displacement lung model, which can simulate lung volumes up to 3.8l and tidal volumes up to 1l. Gas mixing is ensured by using a ring of venturi devices. Model compliance and airways resistance are described.
