Modelling of artificial ventilation system¶
This example simulates an artificial ventilation system. The patient is supplied with a specified air flow rate. The lungs are modelled with a progressive mechanical transducer that converts moist air pressure into translational motion. By setting the area over which the moist air exerts pressure equal to one, the displacement in the mechanical transducer becomes a measure of volume, the source of mechanical energy becomes a measure of pressure, the elastic element becomes a measure of elasticity in breathing, and the damper characterises the resistance to breathing.
Oxygen consumption and carbon dioxide release are not considered in this model.
