Question 3

What is FEV1?

Answer 3

Forced expiratory volume in 1 second

Question 4

What is FEV?

Answer 4

forced vital capacity in total

Forced expiratory volume

Question 5

What is PEFR?

Answer 5

Peak expiratory flow rate-initial slope of vitalograph

Maximum rate person can exhale

Question 6

Why would PEFR be lower?

Answer 6

Obstructive disease

Question 7

Function of residual volume

Answer 7

Make sure alveoli doesn’t collapse

Question 8

What can a vitalograph/spirometer not measure?

Answer 8

Residual volume

Question 9

What is resistance?

Answer 9

Ease with which gas flows through conducting airways

With obstructive disease

Question 10

What is compliance?

Answer 10

Ability of lungs to be able to stretch and expand

With restrictive disease

Question 11

What is FEV1/FVC?

Answer 11

The ratio between FEV1 and FVC

Question 12

How does FVC, FEV1, FEV/FVC change with an obstructive disease?

Answer 12

FVC stays the same
FEV1 is lower
FEV1/FVC is lower

Question 13

What would the ratio of FEV1/FVC be of someone with an obstructive disease?

Answer 13

70/80%

Question 14

How does FVC, FEV1, FEV/FVC change with a restrictive disease?

Answer 14

FVC decreases
FEV1 decreases
FEV1/FVC stays the same or increases
