spirometry trace

Question 1

tidal volume

Answer 1

volume of air moved in and out during normal quiet breath

Question 2

inspiratory reserve volume

Answer 2

extra volume that can be inspired with maximal inhalation

Question 3

expiratory reserve volume

Answer 3

extra volume that can be exhaled with maximal effort

Question 4

residual volume

Answer 4

volume remaining in lungs after maximal exhalation

Question 5

minimal volume

Answer 5

volume remaining in lungs if they collapsed

Question 6

vital capacity

Answer 6

volume of air you can shift in and out of your lungs

= tidal volume + inspiratory reserve + expiratory reserve

Question 7

total lung capacity

Answer 7

total volume of lungs when you’ve filled them to max

= vital capacity + residual volume

Question 8

inspiratory capacity

Answer 8

total volume of air you can inspire from rest

= inspiratory reserve + tidal volume

Question 9

function residual capacity

Answer 9

volume remaining in lungs after normal exhalation

= expiratory reserve + residual volume
