| Expiratory Reserve Volume ERV | the volume of air that can be forcibly exhaled after a normal exhale |
| Forced Expiratory Volume FEV | after 1 second volume of air in liters that is forfully exhaled in the 1st second of exhaation |
| Forced Vital Capacity FVC | maximum amount of air exhaled after maximum inspiration during one of the two timed FVCs |
| Functional Residual Capacity FRC | the amount of air remaining in the lungs after a normal expiration |
| Inspiratory Capacity IC | the amount of air that can be inhaled after normal expiration |
| Inspiratory Reserve Volumn IRV | the amount of air that can be forcibly inspired after a normal inhaled |
| Maximal Midexpiratory Flow MMEF | average flow rate during middle half of FVC |

| Tide Volume (VT) | AMOUNT OF air inhled or exhaled during normal breathing about 500ml |
| Total lung Capacity TLC | volume of lungs at peak inspiration; equal to sum of 4 volumes--tidal colume, expiratory reserve volume, inspiration reserve volume, residual volume |
| Vital Capacity VC | amount of air that can be exhaled following forced inspriation &including max experation |
