L17/18 Respiratory Terms

Question 1

vital capacity

Answer 1

max air that can be EXPIRED after FORCED inspiratory effort

VC= Tidal Volume + IRV + ERV

Question 2

tidal volume

Answer 2

volume of air inhaled or exhaled in one normal breath

Question 3

total lung capacity

Answer 3

max amount of air in lungs after max inspiratory effort

so how much air u can possible breathe in forcibly

TLC = Tidal volume + IRV + ERV + Residual Volume

Question 4

expiratory reserve volume

Answer 4

amount of air you can FORCIBLY EXHALATION after NORMAL tidal volume EXHALATION

Question 5

functional residual capacity

Answer 5

vol of air remaining in lungs after normal tidal expiration

FRC = Residual Volume + ERV

Question 6

residual volume

Answer 6

residual air left after MAXIMUM expiration

Question 7

inspiritory capacity

Answer 7

max amount of air that is inspired after quiet expiration
equivalent to tidal volume + inspiratory reserve volume

IC = Tidal Volume + IRV

Question 8

inspiritiry reserve volume

Answer 8

amount of air FORCIBLY inhaled after a normal exhalation
