23.4 measurement of lung fn

Question 1

what is spirometry?

Answer 1

measurement of volume of air that moves into and out of the respiratory system

Question 2

what device measures the volume of air that moves into and out of the resp system?

Answer 2

spirometer

Question 3

what is the tidal volume?

Answer 3

amt of air inspired or expired with each quiet breath

Question 4

what is the amt of the tidal volume?

Answer 4

500 mL

Question 5

what is the inspiratory reserve volume?

Answer 5

the amount of air that can be inspired forcefully after inspiration of the tidal volume

Question 6

what is the amount of the inspiratory reserve volume?

Answer 6

approx 3000 mL

Question 7

what is the expiratory reserve volume?

Answer 7

the amount that can be forcefully expired after expiration of the tidal volume

Question 8

what is the amount of the expiratory reserve volume?

Answer 8

approx 1100 mL

Question 9

what is the residual volume?

Answer 9

volume still remaining in respiratory passages and lung after most forceful expiration

Question 10

what is the amount of the residual volume?

Answer 10

approx 1200 mL

Question 11

what is the inspiratory capacity?

Answer 11

tidal volume plus inspiratory reserve volume

Question 12

what is the functional residual capacity?

Answer 12

expiratory reserve volume plus residual volume

Question 13

what is the vital capacity?

Answer 13

sum of inspiratory reserve volume, tidal volume and expiratory reserve volume

Question 14

what is the total lung capacity

Answer 14

sum of inspiratory and expiratory reserve volume plus tidal volume plus residual volume
