Spirometry

Question 1

Define Spirometry

Answer 1

Assessing lung function by measuring the volume of air that the patient is able to expel from the lungs after a maximal inspiration

Question 2

what lung function patterns is it used to differentiate

Answer 2

1. Obstructive
2. Restrictive

Question 3

what is FEV1 stand for

Answer 3

Forced Expiratory Vol. in 1 sec

Question 4

Define FEV1

Answer 4

The volume exhaled in the first sec after deep inspiration and forced expiration

Question 5

FVC

Answer 5

Forced Vital Capacity

Question 6

Define Forced Vital Capacity

Answer 6

Total volume of air that a patient can forcibly exhale in one breath

Question 7

FEV1/FVC

Answer 7

The ratio of FEV1 to FVC

Question 8

what pattern is FEV1/FVC < 0.7

Answer 8

Obstructive pattern

Question 9

Reversibility testing in spirometry

Answer 9

SABA - wait 15 mins and repeat spirometry
- 12% reversibility confirms Aathma

Question 10

Precautions before Spirometry

Answer 10

• Stop SABA 6 hours before testing
• Stop LABA 12 hours before testing

Bronchiectasis
Cystic fibrosis

Question 12

Pulmonary causes of restrictive lung disease include:

Answer 12
