Asthma control is a measure of the reduction in symptoms, prevention of exacerbations, and maintenance of good lung function. Current guidelines state that well controlled asthma requires no symptoms, no exacerbations, and normal lung function.1
Health professionals should tailor asthma review to allow for patient preference (including frequency of professional review), as well as asthma severity, risk of severe attacks, and the type of maintenance treatment plan in place.2

Is the new EU-scale meter the same as the ATS-scale meter?
No. Whilst the scale may look similar, only meters that display the text ‘EN 13826‘ have been tested to the new standard. The EN13826 standard includes two important ‘airflow waveforms’ that are not part of the ATS test procedure for peak flow meters. Some ATS-scale meters have already been shown as failing the new EN 13826 standard .
Asthma severity is based on clinical features, as defined in the following table:
|Classification||Day-time symptoms||Night-time symptoms||PEFR*||PEFR variability**|
|Intermittent||1 time per week or less||Twice per month or less||=/>80%||<20%|
|Mild persistent||1 time per week or more but less than once per day||Twice per month or more||=/>80%||=20-30%|
|Moderate persistent||Daily||Once a week or more||=60-80%||30%|
|*PEFR = peak expiratory flow rate as a percentage of expected PEFR according to patient age and height
**PEFR variability = the difference between morning and evening flow rates

The Global Asthma Report 2011 http://www.globalasthmareport.org
Asthma affects 235 million people today and prevalence is rising. Low- and middle-income countries suffer the most severe cases.
We have the tools to counter the devastating personal and economic impact of untreated and poorly managed asthma.
The British Asthma Guideline recommends the Royal College of Physicians three questions to assess asthma control over the preceding month.
