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 .
