RES 201

spirometer is used to measure all of the following except:

• TV (tidal volume)

• FRC (functional residual capacity)

• IRV (inspiratory reserve volume)

• VC (vital capacity)

is considered as an index of pulmonary functions:

• TV (tidal volume)

• VC (vital capacity)

• RV (residual volume)

• FRC (functional residual capacity)

VC is high in all the following except:

• males

• athletes

• pregnant females

• standing position

the volume represented by (D) is ............. in obstructive lung diseases:

• increased

• decreased

• not changed

inspiratory capacity is represented by letter:

• E

• A

• B

• G

the amount of air remaining in the lung after normal expiration is:

• RV

• FRC

• TLC

• ERV

the maximum amount of air remaining in the lung after maximum inspiration is:

• FRC

• TLC

• RV

• IC

the amount of air remaining in the lung after maximum expiration is :

• FRC

• TV

• TLC

• RV

regarding FRC, all are true except:

• the amount of air remaining in the lung after normal expiration

• measured by helium dilution

• is a good index for inspiration

• equals RV+ ERV

all of the following decrease in COPD except:

• TV

• RV

• ERV
