Spirometry ;) Flashcards
Tidal Volume
Amount of air inhaled or exhaled in one breath
Inspiratory Risdual Volume
Amount of air in excess to tidal volume that can be inhaled with maximum effort
Expiratory reserve volume
Amount of air in excess to tidal expiration that can be exhaled with maximum effort
Residual Volume
Amount of air remaining in lungs after maximum expiration
Vital Capacity
Amount of air that can be exhaled with maximum effort after inspiration
Inspiratory Capacity
Maximum amount of air that can be inhaled after a normal tidal volume expiration
FRC
Amount of air remaining in the lungs after a normal tidal expiration
TLC
maximum amount of air lungs can contain
Tidal Volume typical value
500ml
IRV typical value
3000ml
ERV typical value
1200ml
RV typical value
1200ml
VC typical value
4700ml
IC typical value
3500
FRC typical value
2400
TLC typically value
5900ml
How do you calculate inspiratory capacity
IC= TV + IRV
How do you calculate VC
ERV + TV + IRV
How do you calculate TLC
RV + VC or IRV + TV + ERV+ RV
What is forced expiratory volume in one second
person takes a maximal inhalation and then exhales as fast as possible
What is the typically healthy value of FEV1
80%
What do people with restrictive lung diseases cannot do
cannot fully fill their lungs with air
-also usually have FEV1 greater than 80%
Pulomonary Fibrosis
buildup of scar tissue in the lungs
Interstitial Lung Disease
buildup of scar tissue, fluid, and inflammation in intersitial space
