Why the choice of a peak flow meter for lung function testing?
• How do peak flow recording assist us in asthma control? • How to use a mini peak flow meter • The recording of peak flow measurements • Important practical applications of the peak flow What is peak flow? Return to the top • Asthma is a condition where the airways (bronchi), through which the air is breathed in and out of the lungs, become narrowed. • Lung function tests applicable to asthma are used to measure the flow and volume of air moving through the airways. This information gives the doctor a picture of the status of the child’s asthma at the time of testing. • The peak flow rate is a relatively simple function test which measures how fast the maximum amount of air can be blown out the airways. It is measured in litres per minute. • The peak flow is obtained by the child taking a deep breath as possible (maximum inspiratory volume), and then blowing out through the peak flow meter as hard and as fast as they are able. The reading so obtained gives the highest now of air achie
