  1. DL - diffusing capacity of the lung
    milliliters of gas the lung can transfer to the blood
  2. ERV - expiratory reserve volume
    amount of air you can exhale after a normal exhalation
  3. VT - tidal volume
    amount of air you can inhale after a normal exhalation
  4. IRV - inspiratory reserve volume
    amount of air you can inhale after a normal inspiration
  5. RV - residual volume
    air left in the lungs after a maximum exhalation
  6. TLC - total lung capacity
    largest amount of air the lungs can hold
  7. VC - vital capacity
    amount of air you can exhale after a maximum inspiration
  8. IC - inspiratory capacity
    volume inspired with a normal breath
  9. FRC - functional residual capacity
    air left in the lungs after a NORMAL exhalation
  10. MVV - maximal voluntary ventilation
    greatest amount of air you can breathe in 12 to 15 seconds
  11. FVC - forced vital capacity
    amount of air you can exhale after a MAXIMUM inspiration
  12. PEF - peak expiratory flow rate
    fastest flow rate generated at the very beginning of forced exhalation
  13. FEF 200-1200 / forced expiratory flow rate btwn 200-1200ml
    average expiratory flow during the early part of forced exhalation
  14. FEV1 - forced expiratory volume in 1 seconds
    volume of air you can forcefully exhale in 1 second
  15. FEF 25%-75% - forced expiratory flow
    average expiratory flow during the middle part of forced exhalation
  16. FEV1/FVC - forced expiratory volume 1 second/forced vital capacity ratio
    volume of air you can forcefully exhale in 1 second
