7.3 Measuring The Process

Question 1

What ways can you measure the capacity of the lungs

Answer 1

Peak flow meter
Vitalographs
A spirometer

Question 2

What is a peak flow meter

Answer 2

Measures the rate at which air can be expelled from the lungs

Question 3

What is a vitalograph

Answer 3

More sophisticated than peak flow

Patient breaths out as quickly as they can through a mouthpiece and Intrument produces a graph of results

Question 4

What is a spirometer

Answer 4

Measure different aspects of the lung volumes

Question 5

What is tidal volume

Answer 5

Amount of air that moves into and out of the lungs with each resting breath

Question 6

What is vital capacity

Answer 6

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

Question 7

What is inspiratory and expiratory reserve volume

Answer 7

IRV - max vol of air you can breath in after normal inhalation
ERV- max vol of air you can breath out after normal exhalation

Question 8

What is residual vol

Answer 8

Vol of air that’s left in the lungs when you’ve exhaled as hard as possible

Question 9

What is total lung capacity

Answer 9

Sum of vital capacity and residual volume

Question 10

How do you work out ventilation rate

Answer 10

Tidal volume x breathing rate per minute
