A) Define these terms. Don’t just explain the abbreviation. Give a functional definition.
IRV
TV
ERV
RV
IV
FRC
VC
TLC
B) Give one way of calculating each of the following:
TLC =
VC =
IC =
FRC =
C) TLC = 6500 VC = 5000 Find RV.
TLC = 6500 IC = 3500 Find FRC.
TLC = 6500 RV = 1200 Find VC.
IC = 3500 TV = 600 Find IRV.
FRC = 2300 RV = 1200 Find ERV.
D) The total volume of air in Jeffrey’s lungs is 5800 mL. If his IC is 3200 and his RV is 1000, calculate his ERV and FRC.
TLC = 4200, VC = 3200, IC = 2000 Calculate the FRC and RV?
VC = 3200, IC = 2200, ERV = 1000, RV = 1000 Calculate the TLC.
The total volume of air Sally can inhale after a quiet exhalation is 3400 mL. When Sally is sitting still she inhales 400 mL and there is 2200 mL left in her lungs. Calculate or figure out from the information given in the question the following values TV, TLC, IC, FRC, IRV.
When at rest Jeremy inspires and expires 600 mL. While his lungs can hold 7000 mL of air only 5500 mL can move in and out, if he really, really tries. Normally, there is 3400 mL of air left in his lungs after a quiet expiration. Calculate or figure out TV, ERV, TLC, IC, FRC, IRV, RV.
A) IRV : inspiratory reserve volume is the volume of air
forcefully inspired after a normal inspiration. Normal value :
1900-3300ml.
TV : Tidal volume is the volume of air entering the lungs after
quiet normal inspiration. Normal value : 500ml
ERV: Expiratory reserve volume is the amount of air that can be
exhaled forcefully from lungs after a normal expiration. Normal
value: 700-1100 ml
RV : residual volume is amount of air that remains in the lungs after a maximum expiration. Normal value: 1100-1200ml
IV: inspiratory vital capacity is the maximum amount of air a
person can inhale after a maximal exhalation.
FRC : functional residual capacity is the amount of air contained
within the lungs after normal expiration. Normal value : 2.5L
VC : vital capacity is the amount of air exhaled after a deep
inspiration. Normal value : 3100-4800 ml.
TLC : total lung capacity is the amount of air contained in lungs
after a forced inspiration. Normal value : 4-6 L
