Description

Our Lung Function Calculator Wheel enables simple and rapid comparison of an individual's peak expiratory flow rate (PEFR) against standard reference values, which helps a clinician to demonstrate how treatment is effective in improving airway disease (e.g. COPD or asthma) or the benefits of stopping smoking.

The calculator wheel is double-sided, with values for children between 5 and 18 years of age on one side and values for adults between 18 and 70 years of age on the other side.
