Question 1

Define total lung capacity and provide the normal range

Answer 1

Volume of air in the lungs upon maximal inspiration

5-6L

Question 2

Define tidal volume and provide the normal range

Answer 2

The amount of air we breathe in and out during normal breathing

500mL

Question 3

Define vital capacity and provide the normal range

Answer 3

Max amount of air expired from a fully inflated lung (tidal vol + IRV + ERV?)

4L

Question 4

Define residual volume and provide the normal range

Answer 4

Air left in the lungs after a maximal expiration

1L

Question 5

Define functional residual volume and provide the normal range?

Answer 5

Volume of air remaining in lungs after expiration of a normal breath (Residual volume + ERV)

Normal: 3-4L?

Question 6

Define expiratory reserve volume and provide the normal range?

Answer 6

The amount of air we can exhale in addition to the tidal volume is the expiratory reserve volume

2L

Question 7

Define inspiratory reserve volume and the normal range

Answer 7

The air inspired in a maximal inspiratory effort in excess of the tidal volume

1L
