Week 9 (Spirometry)

Question 1

Spirometry is…

Answer 1

An objective and reproducible measurement of lung function

Question 2

FEV1 (forced expiratory volume in 1 second) is…

Answer 2

Volume of air that can be forcibly be blown out in one second after full inspiration

Question 3

FVC (forced vital capacity) is…

Answer 3

After full inspiration, maximum volume of air that can be forcibly expired in one breath

Question 4

Normal value of FEV1/FVC

Answer 4

75-80%. Abnormal <70%.

Question 5

FEV1 is representative of

Answer 5

Obstructive disease

Question 6

FEV1/FVC is representative of

Answer 6

Obstructive disease

Question 7

Normal value of FVC

Answer 7

> 80% of predicted

Question 8

Normal value of FEV1

Answer 8

> 80% of predicted

Question 9

Obstructive disease…

Answer 9

Patient cannot exhale air in the lungs quickly as something is obstructing their airways -> reduced FEV1, FVC is often preserved

Question 10

Mild obstruction value

Answer 10

> 80%

Question 11

Moderate obstruction value

Answer 11

50-80%

Question 12

Severe obstruction value

Answer 12

30-50%

Question 13

Very severe obstruction value

Answer 13

<30%

Question 14

Restrictive disease…

Answer 14

Something restricts the intake of air into the lungs therefore the lung volumes are reduced -> mainly reduced FVC, FEV1 is reduced or normal, FEV1/FVC is normal or increased

Question 15

Obstructive disease can be obstructed from

Answer 15

Bronchospasm, inflammation, secretions/mucus, loss of elasticity in bronchial walls

Question 16

Restrictive disease can be restricted from

Answer 16

Pulmonary fibrosis, scoliosis, obesity, MND, SCI

Question 17

Mixed restrictive and obstructive disease is…

Answer 17

Issue with both intake of air into lung and exhaling of air out of lungs
