What is the volume of air that cannot be voluntarily shifted called?

Residual volume

5

How large is residual volume?

1.2L

6

What is residual volume needed for?

What is tidal volume?

A normal breath, 500ml

9

What is the volume of air breathed in or out of the lungs at each breath called?

Tidal volume, TV

10

What is expiratory reserve volume, ERV?

Maximum volume of air which can be expelled from the lungs at the end of a  normal expiration

11

What is the maximum volume of air which can be expelled from the lungs at the end of normal expiration called?

Expiratory reserve volume, ERV

12

What is inspiratory reserve volume, IRV?

Maximum volume of air which can be drawn into the lungs at the end of a normal inspiration

13

What is the maximum volume of air which can be drawn into the lungs at the end of a normal inspiration called?

Inspiratory reserve volume, IRV

14

What is residual volume, RV?

Volume of gas in the lungs at the end of a maximal expiration

15

What is the volume of air in the lungs at the end of a maximal expiration called?

Residual volume, RV

What does total volume + inspiratory reserve volume + expiratory reserve volume make?

Vital capacity, VC

18

What is total lung capacity, TLC?

Vital capacity + residual volume

19

What does vital capacity + residual volume make?

Total lung capacity, TLC

20

What is inspiratory capacity, IC?

Tidal volume + inspiratory reserve volume

21

What does tidal volume and inspiratory reserve volume make?

Inspiratory capacity, IC

22

What is functional residual capacity, FRC?

Expiratory reserve volume + residual volume

23

What does expiratory reserve volume + residual volume make?

Functional residual capacity, FRC

24

What is FEV1?

Forced expired volume in 1 second

25

What is the forced expired volume in 1 second called?

FEV1

26

What is FEV1:FVC?

Fraction of forced vital capacity expired in 1 second

27

What is ventilation?

Movement of air in and out of the lungs

28

What are the 2 kinds of ventilation?

Pulmonary (minute) ventilation

Alveolar ventilation

29

What is pulmonary (minute) inspiration?

Total air movement into/out of lungs

30

What is alveolar ventilation?

Fresh air getting to alveoli and available for gas exchange
