| Zusammenfassung | The complex situation of artificial ventilation, especially the consequences of different ventilator settings for the pressure, flow and volume changes of the patients lung with changing mechanical properties, is modeled by a digital lung mechanics simulator. Different lung mechanics properties, designed as RLC circuits, and different ventilator settings can be interactively chosen. Their influences are continuously computed by a transient analysis and then shown as the dynamically updated courses for the pressure, flow and volume parameters. As these calculated curves agree with measured data from patients the system can be used as a component appropriate for the validation of advising systems which give recommendations about better ventilator settings on the basis of measured data from ventilators. The system is a realistic phantom which covers a wide range for the possible different lung mechanics properties in connection with different settings at the ventilator. Moreover, the implemented models can be used to interpret measured pressure and flow curves from patients in terms of these models, i.e. a quantitative, model based description of the present lung mechanical status is possible by simulation. |
