Pulmonary Function Prac

Question 1

what is spirometry used for?

Answer 1

it is used to measure lung volumes by recording the amount of inhaled and exhaled air

Question 2

what is inspiratory reserve volume?

Answer 2

air that can be received by maximal contraction of the lungs

Question 3

what is vital capacity?

Answer 3

volume of air flowing through the airways at each maximal inspiration or expiration

Question 4

what is tidal volume?

Answer 4

volume of air flowing through the airways at each inspiration or expiration

Question 5

what is the expiratory reserve volume?

Answer 5

air that can be exhaled by maximal contraction of the lungs

Question 6

what is residual volume?

Answer 6

air that still remains in the lungs (still contained in the lungs)

Question 7

what can restrict the diaphragm during inspiration?

Answer 7

pregnancy or a full digestive tract can restrict diaphragm during inspiration (decreasing V T)
because resistance increases resulting in a decreasing tidal volume

Question 8

what effect does physical activity have on resp system?

Answer 8

physical activity elevates both respiratory frequency and VT (tidal volume)

Question 9

what is the normal tidal volume for a horse?

Answer 9

14-15ml/kg BW

Question 10

what is the normal tidal volume for a cat?

Answer 10

7-10ml/kg BW

Question 11

what is the normal tidal volume for a dog?

Answer 11

10-15ml/kg BW
