Answer 1

Chronic obstructive pulmonary disease (COPD)

Question 2

What does expansion of the thoracic cage lead to

Answer 2

An increase in lung volume

Question 3

What is the result of atmospheric pressure being equal to intrapleural pressure

(If lung were punctured )

Answer 3

Lungs would not inflate

Question 4

What changes the volume of the thoracic cage

Answer 4

Skeletal muscles

especially diaphragm

Question 5

Answer 5

Pressure gradient

Question 6

Pressure of air in the atmosphere

(outside the body and lungs)

Answer 6

Atmospheric pressure

Question 7

Pressure of air in the alveoli (air sacs) of the lungs example ( inside the body of the lungs)

Answer 7

Intra alveolar pressure

Question 8

Pressure existing in the plural cavity between the parietal pleural lining and the plural cavity and the visceral pleural covering outside of the lungs

Answer 8

Intrapleural pressure

Question 9

This is used to measure lung volumes and capacities

Answer 9

Spirometer

Question 10

Air flow can be measured to create what (2 things)

Answer 10

1) air flow volume loops
2) diagnose lung diseases

Question 11

This type of disorder results in a flow of air that is less than it should be

Answer 11

Obstructive lung disorders

Question 12

This type of disorder have a normal flow of air but a low vital capacity and a low inspiratory and expiratory volumes

Answer 12

Restrictive lung disorders

Question 13

Volume of air in each breath during regular breathing

Answer 13

Tidal volume

Question 14

The additional volume of air that can be moved into the lungs above tidal volume

Answer 14

Inspiratory reserve volume

Question 15

The additional volume of air that can be moved out of the lungs below tidal volume

Answer 15

Expiratory reserve volume

Question 16

The total amount of movable air

Answer 16

Vital capacity

TV + IRV + ERV

Question 17

The total amount of air forcefully exhaled from fully inflated lungs this is how vital capacity is measured

Answer 17

Forced vital capacity

Question 18

The percentage of the forced vital capacity that is expired in one second

Answer 18

Forced expiratory volume 1

Question 19

The average flow rate of the middle half of the forced vital capacity (index of function)

Answer 19

Forced expiratory flow 25-75

Question 20

Analyzing this will confirm the diagnosis of an obstructive or restrictive lung disease

Answer 20

Flow volume loop

Question 21

This test is used in conjunction with flow tests to differentiate obstructive and restrictive lung disease

Answer 21

Pulmonary volume tests

Question 22

Is it possible for a patient to have both obstructive and restrictive disorders of the lung simultaneously

What would you expect in the lab data of a patient with both obstructive and restrictive disorders

Answer 22

1) Yes
2) reduced lung volume with reduced airflow

Question 23

Answer 23

recognize these
