  • Tidal volume:
    • Adequate tidal volume necessary to maintain oxygenation and co2 clearance
  • Inspiratory reserve volume:
    • Required during cough & undertaking exercise
  • Functional residual capacity:
    • Essential to maintain distal lung patency on expiration
    • Critical value called “closing volume” or “closing capacity"
  • Residual volume:
    • Can increase in lung disease due to “air trapping”
    • When increased may alter respiratory mechanics
  • Functional Residual Capacity:
    • Can reduce in many clinical situations
  • Vital capacity:
    • Critical value ( 1 L ) used to identify if patient is able to maintain spontaneous ventilation
