Measurements of Volume

Question 0

Additional air that can be forcefully exhaled after normal exhalation is complete

Answer 0

Expiratory reserve volume (ERV)

Question 1

Volume of air inhaled and exhaled with each breath

Answer 1

Tidal Volume

Question 2

Amount of air remaining in lungs after forced expiration; air available in lungs for gas exchange between breaths

Answer 2

Residual Volume (RV)

Question 3

Maximum volume of air that can be inhaled forcefully after normal inhalation

Answer 3

Inspiratory reserve volume (IRV)

Question 4

Maximum volume of air that lungs can contain

Answer 4

Total lung capacity (TLC)

Question 5

Maximum volume of air that can be exhaled after maximum inspiration. higher for men (generally)

Answer 5

Vital Capacity (VC)

Question 6

Maximum volume of air that can be inhaled after normal expiration

Answer 6

Inspiratory capacity (IC)

Question 7

Amount of air that can be quickly and forcefully exhaled after maximum inspiration

Answer 7

Forced Vital Capacity (FVC)

Question 8

Amount of air exhaled in first second of FVC

Answer 8

Forced expiratory volume in first second

Question 9

Measurement of airflow rate in middle half of forced expiration; early indicator of disease of small airways

Answer 9

Forced midexpiratory flow rate

Question 10

Deep breathing as rapidly as possible for specified period; fairly nonspecific test that gives information about exercise capacity; used in conjunction with exercise stress test

Answer 10

Maximal voluntary ventilation

Question 11

Maximum airflow rate during forced expiration; aids in monitoring bronchoconstriction in asthma; can be measured with peak flow meter

Answer 11

Peak expiratory flow rate
