| |
| The '''peak expiratory flow''' ('''PEF'''), also called '''peak expiratory flow rate''' ('''PEFR''') is a person's maximum speed of expiration, as measured with a '''peak flow meter''', a small, hand-held device used to monitor a person's ability to breathe out air. It measures the airflow through the [[bronchus|bronchi]] and thus the degree of obstruction in the airways.
| |
| | |
| ==Function==
| |
| Peak flow readings are higher when patients are well, and lower when the airways are constricted. From changes in recorded values, patients and doctors may determine lung functionality, severity of asthma symptoms, and treatment options.
| |
| | |
| First measure of precaution would be to check patient for signs and symptoms of asthmatic hypervolemia. This would indicate whether or not to even continue with the Peak Flow Meter procedure.
| |
| Measurement of PEFR requires training to correctly use a meter and the normal expected value depends on a patient's sex, age and height. It is classically reduced in obstructive lung disorders such as [[asthma]].
| |
| | |
| Due to the wide range of ‘normal' values and high degree of variability, peak flow is not the recommended test to identify asthma. However, it can be useful in some circumstances.
| |
| | |
| A small portion of people with asthma may benefit from regular peak flow monitoring. When monitoring is recommended, it is usually done in addition to reviewing asthma symptoms and frequency of reliever medication use.<ref>National Asthma Council of Australia</ref>
| |
| | |
| When peak flow is being monitored regularly, the results may be recorded on a peak flow chart.
| |
| | |
| It is important to use the same peak flow meter every time.

| | Red Zone
| |
| | Less than 50 percent of the usual or normal peak flow readings

| ==History==
| |
| The measurement of peak expiratory flow was pioneered by [[Martin Wright (bioengineer)|Martin Wright]], who produced the first meter specifically designed to measure this index of lung function. Since the original design of instrument was introduced in the late 1950s, and the subsequent development of a more portable, lower cost version (the "Mini-Wright" peak flow meter), other designs and copies have become available across the world. In January 2014, a new instrument used in the estimation of PEFR was discovered by Dr Osarogiagbon and a medical student Kokomo Abosede Ajoke. This instrument, named the 'Mini-Joke' peak flow meter gives PEFR values with accuracies within the ranges of 95-98%.
