Spirometry

Question 1

What is the purpose of pulmonary function tests?

Example?

Answer 1

• used to detect lung diseases or to monitor the progression or a particular disease, such as chronic obstructive pulmonary disease
• Spirometry

Question 2

Lung volumes and capacities

Answer 2

Question 3

Define Tidal volume (VT)

Question 4

Define inspiratory reserve volume (IRV)

Answer 4

-force inhalation after normal inhalation

Question 5

Define Expiratory reserve volume (ERV)

Answer 5

-amount of air forcefully exhaled by contraction of both groups of muscles

Question 6

Define residual volume (RV)

Answer 6

• amount of air left in the lungs after maximum forced exhalation
• makes it easier to inflate the lungs during the next inhalation and oxygenates the blood between ventilation cycles

Question 7

How do you find Tidal Volume (VT) and respiratory minute volume using a spirometer?
