Development of a concentric water-displacement model lung

J Biomed Eng. 1993 Sep;15(5):420-4. doi: 10.1016/0141-5425(93)90080-i.


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 3.8 l and tidal volumes up to 1 l. Gas mixing is ensured by using a ring of venturi devices. Model compliance and airways resistance are described.
