Anderson - Compliance, Recoil, Surfactant, Airway Resistance

Instructor(s): Lisa Anderson

Session Objectives:

  1. Draw normal pressure-volume curves for the lung. Explain why these curves are different during inspiration and expiration.
  2. Define compliance of either lung of the total respiratory system. Be able to calculate lung compliance and identify two common clinical conditions in which the lung compliance is higher or lower than normal
  3. Define surface tension as it applies to the lungs, including the role of surfactant. Define atelectasis, and explain the role of surfactant in preventing it.
  4. Describe the roles of airway diameter and turbulent flow on airway resistance. Explain how airway resistance changes with lung volume.
  5. Explain why pulmonary emphysema is an obstructive lung disease.
  6. Define dynamic airway compression and compare dynamic compression in healthy versus emphysema lungs
