Lecture 10-Lung Function Testing Flashcards
1
Q
Why are lung function tests used?
A
- help diagnosis
- monitor patient changes
- research
2
Q
What can be learnt from forced flow-volume measurements?
A
- how much air can the patient blow out?
- how fast is the air expelled?
- pattern of change in flow-volume curve can show site of obstruction
- response to treatment
- change with age/growth
- disease progression

3) reduced
5
Q
Describe the:
1) FEV1
2) FVC
3) FEV1/FVC in a patient with a restrictive disorder
A
1) appropriate for FVC
2) reduced
3) normal
6
Q
True or false: FVC standing < FVC seated
A
FALSE - other way round
7
