Model number

This is a one compartment lung mechanic model.



OneCompLung Pic1


A model of a single compartment compliant lung.  Ventilation is driven by 
positive pressure oscillatory pressure source (Psource) that produces 
bi-directional airflow.

The fluid (air) is assumed incompressible (but may be over 1%, e.g.770/760 
compression). The air flows into and out of a single compliant well-mixed 
compartment, V1. 

Mathematically, this lung model analogous to a single open loop 
resistor-capacitor electric circuit. 

This model is the first in the pulmonary gas exchange tutorial

The equations for this model may be viewed by running the JSim model applet and clicking on the Source tab at the bottom left of JSim's Run Time graphical user interface. The equations are written in JSim's Mathematical Modeling Language (MML). See the Introduction to MML and the MML Reference Manual. Additional documentation for MML can be found by using the search option at the Physiome home page.
