Lung Capacities

• Functional residual capacity (FRC)

  • Lung volume at end of normal quiet expiration
  • (Expiratory reserve volume + Residual volume )
• Vital capacity (VC)

  • Volume air maximal inspiration to maximal expiration
  • (Inspiratory reserve volume + Tidal volume + Expiratory reserve volume)
• Total lung capacity (TLC)

  • Volume maximal inspiration to residual volume
  • (Inspiratory reserve volume + Tidal volume + Expiratory reserve volume + Residual volume)
