“Create a causal loop diagram for asthma with airway trigger exposure, airway inflammation, bronchoconstriction, airflow obstruction, respiratory effort and airway irritation. Show the reinforcing loop in which inflammation increases obstruction and respiratory effort, which increases airway irritation and inflammation.”
Comprenez les décisions qui le sous-tendent.
Separate inflammation and bronchoconstriction.
Keep every worsening relationship positive.
Name the airway irritation feedback.
Keep the example qualitative.
Use for learning and discussion, not for individual asthma management.
Questions fréquentes
What does a positive arrow mean?
It means the variables tend to move in the same direction, all else being equal.
Why is this loop reinforcing?
Increased inflammation can contribute to changes that create more airway irritation and inflammation.
Can medication be modelled?
Yes. A bronchodilator can be added as a balancing influence that reduces bronchoconstriction.
