Question 1

FEV1 is the blank

Answer 1

volume of air expired during first second of FVC measurement

Question 2

fvc is the blank

Answer 2

forced vital capacity

Question 3

during inspiration the blank contracts which creates a blank thoracic cavity

Answer 3

diaphragm, larger

Question 4

enlarged thoracic cavity leads to a blank in pressure in the pleural space and alveoli

Answer 4

decrease

Question 5

Palv means the pressure inside the blank

Answer 5

alveoli

Question 6

Pple means the pressure inside the blank

Answer 6

pleural space

Question 7

pressure gradient across lung wall

Answer 7

transpulmonary pressure

Question 8

transpulmonary pressure equation

Answer 8

PT = Palv - Pple

Question 9

Ppl is always blank due to blank property of lung and chest wall

Answer 9

negative, elastic

Question 10

transpulmonary pressure is always blank in normal breathing

Answer 10

positive

Question 11

normal FEV1 / FVC is about blank

Answer 11

80%

Question 12

increased airway resistance especially during expiration in this disease

Answer 12

obstructive

Question 13

in obstructive disease blank flow is obstructed

Answer 13

expiratory

Question 14

in an obstructive disease FEV1 / FVC is blank

Answer 14

decreased

Question 15

in blank lung disease blank is restricted and FEV1 / FVC is blank

Answer 15

restrictive, inflation, normal
