Question 1

What are factors that impact lung capacity?

Answer 1

1. Ages
2. Gender
3. Height

Question 2

Tidal volume (TV)

Answer 2

volume of air expired or inspired during quite breathing

Question 3

Inspiratory Reserve Volume (IRV)

Answer 3

volume of air that can forced in after tidal volume

Question 4

Expiratory Reserve Volume (ERV)

Answer 4

volume of air that can be forced out after tidal volume

Question 5

Residual Lung Volume (RVL)

Answer 5

volume of air left in the lungs after maximum expiration

Question 6

What is Vital Capacity (VC) and how do you calculate it?

Answer 6

maximum volume of air that can be forcefully exhaled after maximum inhalation
- VC= TV+IRV+ERV

Question 7

Total Lung capacity

Answer 7

the volume of gas in the lungs after a maximum inspiration
- TLC=TV+IRV+ERV+RLV

Question 8

What is the difference in the Collins Spirometry graph and the Handheld Spirometry?

Answer 8

Collins = IRV is downward and ERV is upward
Handheld= IRV upward and ERV is downward

Question 9

What is measured and calculated in Spirometry

Answer 9

1. FVC
2. FEV 1.0
3. FEV 1.0/ FVC ratio

Question 10

FVC?

Answer 10

Forced Vital Capacity

Question 11

FEV 1.0?

Answer 11

Forced Expiratory Volume in 1 second
- Indicates how fast air can be expired from your lungs in one second

Question 12

if or FEV 1.0/FVC percentage is greater than 70% what does that indicate?

Answer 12

Normal Lung Capacity

Question 13

What happens to Fev 1.0 valve and ore ration during an obstructive Pulmonary Dysfunction?

Answer 13

FEV 1.0 will be lower than normal and FVC will be normal and or the ratio will be lower than 70 percent

Question 14

REstrictivve Pulmonary Dysfunction

Answer 14

Both FVC and FEV 1.0 values will be lower than normal and ratio will be greater the 70%
