Q

Place the following terms in order based off the process of obstructive airway diseases:

  1. obstruction
  2. irritant
  3. inflammation
  4. infection
  5. elastic recoil destroyed
A

Irritant->inhalation leads to airway and alveolar inflammatory response, continues as long as irritant is present, long exposure will cause irreversible damage
Infection->speeds process
Inflammation->starts in small airways of lungs, breaks down elastin and connective tisssue, leads to hyperplasia and mucus secretion
Obstruction->hypersecretion of mucus, mucus plugging, edema, increased reactivity and eventual bronchial fibrosis and destruction of terminal airways
Elastic recoil destroyed

Q

Name that dyfunction:
Expiration: mucous plugs and narrowed airways cause air trapping and hyperinflation on expiration, decreased elastic recoil of bronchial walls results in collapse of airways and prevents normal expiatory airflow

Inspiration: airways pulled open, allowing gas to flow past the obstruction
