Pulmonary Volumes Flashcards
1
Q
tidal volume (TV)
A
amount of air exchanged with normal inspiration and expiration
2
Q
residual volume (RV)
A
volume of air left in lungs after forced expiration
3
Q
inspiratory capacity (IC)
A
how much air we can take in after a normal expiration
4
Q
inspiratory reserve volume (IRV)
A
- maximum volume of air inspired in excess of normal tidal volume
- = inspiratory capacity – tidal volume
5
Q
expiratory reserve volume (ERV)
A
- maximum volume of air expired following a normal expiration
- = tidal volume – residual volume
6
Q
vital capacity (VC)
A
- maximum amount of air expired following a maximal inspiration
- = tidal volume + IRV + ERV
7
Q
total lung capacity (TLC)
A
total volume of air in the lungs after maximum inspiration
8
Q
forced expiratory volume in 1 second (FEV1)
A
- amount of air exhaled as hard as possible in 1 second after maximum inhalation
- used to test pulmonary function
