A manual peak flow meter is a handheld device used to measure the maximum speed of air a person can exhale from their lungs, known as peak expiratory flow. It is commonly used by patients with asthma or other chronic respiratory conditions to monitor lung function at home or in clinical settings, helping track changes in respiratory status over time.
These devices are typically supplied as non-invasive, single-patient-use or reusable tools that require no power source and are operated by the user blowing into a mouthpiece. Regulation varies by jurisdiction, but they are generally classified as low-risk medical devices based on their mechanical design and intended use for monitoring rather than treatment.
