About Peak Flow (PEF)

The Peak Flow (PEF) tool provides an estimate of an individual's expected peak expiratory flow rate, calculated based on their age and height. This resource is invaluable for individuals actively managing respiratory conditions such as asthma or COPD, and for healthcare professionals requiring a quick, personalized reference. By offering a data-driven benchmark, the tool empowers users to accurately interpret their daily peak flow meter readings. This enables better monitoring of lung function, early detection of significant deviations from expected norms, and more informed decisions regarding respiratory health management and potential treatment adjustments.
