7500 mL/min

Question 3

Anatomic dead space is how much

Answer 3

150 mL

Question 4

What is the frequency of breaths

Answer 4

15 breaths per minute

Question 5

What is the volume of alveolar gas

Answer 5

3000 mL

Question 6

What is the amount of alveolar ventilation

Answer 6

5250 mL/min

Question 7

What is the pulmonary capillary blood volume

Answer 7

70 mL

Question 8

What is the pulmonary blood flow

Answer 8

5000 mL/min

Question 9

The ideal perfect lung has what V/Q ratio

Answer 9

1

Question 10

At the level of a single alveolus, in turns of the ventilation perfusion ratio

Answer 10

Alveolar ventilation : capillary flow

Question 11

At the level of the whole lung, in terms of ventilation-perfusion ratio

Answer 11

Total ventilation : cardiac output

Question 12

V/Q ratio > 1 means

Answer 12

Ventilation exceeds perfusion

Question 13

V/Q ratio < 1 means

Answer 13

Perfusion exceeds ventilation

Question 14

A normal V/Q ratio is what

Answer 14

0.8, so perfusion exceeds ventilation
