1. For each description below write: a) in the large blank the
name of the volume described, and
b) the letter of this volume from the diagram.
1. a) b) The volume of a normal restful breath.
2. a) b) Maximum volume which can be exchanged in a single breath
3. a) b) Maximum inspiration beyond a restful inspiration.
4. a) b) Maximum expiration beyond a restful expiration.
5. a) b) Volume of air remaining after a maximum
expiration
II. Answer the following in the spaces provided: GIVEN: tidal volume = 400 cc.,
expiratory reserve volume = 1000 cc., vital capacity = 4000 cc., breaths per minute = 12,
conducting zone = 150 cc.
6. Calculate the inspiratory reserve volume:
7. Calculate the minute volume:
8. Calculate the alveolar ventilation rate:
9. What additional volume must be known to calculate the total lung capacity?
10. What minimum level of the vital capacity would yield a normal
FEV1,?
Circle the correct answers for questions, or fill in blank where appropriate..
11. At its maximum, the intrapulmonary pressure would be:
(A) +1 to +3 mmHg, (B) -1 to -3 mmHg.
12. At its maximum, the intra-pleural pressure would be:
(A) +1 to +3 mmHg, (B) -I to -3 mmHg.
13. As a gas increases in volume, its pressure: (A) increases, (B) decreases.
14. As the diaphragm contracts, the lung volume (A) increases, (B) decreases,
causing the
pressure in the lungs to (A) increase, (B) decrease, and therefore causing
air to
(A) enter, (B) depart, the lungs.
15. Given the following values for P02, place them next to the appropriate location.
P02: 160, 100, 95, 40, <40.
atmospheric air:
alveolar air:
pulmonary venous blood:
pulmonary arterial blood:
systemic tissues
16. An increase in PCO2 will cause
(A) increased, (B) decreased dissociation of oxygen from
hemoglobin and this phenomenon occurs in the (A) lungs, (B) systemic tissues.
17. The primary immediate response to a significant gain in altitude is the release of _?_ by red blood cells which enhances oxygen (A) dissociation, (B) association
thus delivering (A) more, (B) less oxygen to tissues.
1. a) tidal volume b) A
2. b) vital capacity b) E
3. a) inspiratory reserve volume b) B
4. a) expiratory reserve volume b) C
5. a) residual volume b) D
6. 2600 (VC-[TV+IRV])

13. B
14. A, B, A
15. Atmosphere = 160, alveolar air = 100, pulmonary venous blood = 95, pulmonary arterial blood = 40, systemic tissues <40.
16. A, B
17. A, A
