Model number


Four segment (larynx, trachea, bronchi, alveoli) pressure-flow model represents the respiratory system and it is driven by pleural pressure.


  This model represents the airway with four segments: the larynx, trachea, 
  bronchi, and alveoli. The pressure is applied to the compliances, Com2, Com3, 
  Com4, of the three segments that are within the chest cavity.
