7.3 - Measuring The Process

Question 1

What is a peak flow meter?

Answer 1

A device that measures the rate at which air can be expelled from the lungs

Question 2

What is a spirometer?

Answer 2

Used to measure different aspects of lung volume or to check breathing patterns

Question 3

What is Tidal volume?

Answer 3

The volume of air that moves in and out if the lungs with each resting breath

Question 4

What is Vital Capacity?

Answer 4

The volume of air that can be breathed in when the strongest possible exhalation is followed by the deepest possible intake of breath.

Question 5

What is Inspiratory Reserve Volume?

Answer 5

The maximum volume of air you can breathe in over and above a normal inhalation

Question 6

What is Expiratory Reserve Volume?

Answer 6

The extra amount of air you can force out after the normal tidal volume you breathe out

Question 7

What is Residual Volume?

Answer 7

The volume of air left in the lungs after you exhale as much as possible. This cannot be measured directly

Question 8

What is Total Lung Capacity?

Answer 8

The sum of the vital capacity and the residual volume

Question 9

What is the breathing rate?

Answer 9

The number of breaths taken in a minute

Question 10

What is the ventilation rate?

Answer 10

The total volume of air inhaled in one minute

Ventilation rate = tidal volume x breathing rate (per minute)
