II. Definition

  1. Maximal volume expelled after maximal inspiration

III. Calculation

  1. Components (additive)
    1. Inspiratory Reserve Volume (IRV) +
    2. Expiratory Reserve Volume (ERV) +
    3. Tidal Volume (TV)
  2. Normal adult: 3 to 5 Liters
  3. Gender Differences (values are >80% of predicted)
    1. Females: 50 to 60 cc/kg
    2. Males: 70 cc/kg
  4. Advancing age after 20 years
    1. Vital Capacity decreases 200 to 250 cc per 10 years
  5. Calculations based on height
    1. Females: (27.63 - (0.112 x age)) x (height cm)
    2. Males: (21.78 - (0.101 x age)) x (height cm)
