Portable Peak Flow Meter for Asthma Monitoring

The Peak Flow Meter is a portable respiratory monitoring device used to measure Peak Expiratory Flow (PEF)—the maximum speed at which a person can forcefully exhale air from the lungs. It is commonly used by people with asthma and other obstructive airway conditions to monitor changes in airflow and help identify worsening respiratory symptoms. Many models include an easy-to-read scale and adjustable green, yellow and red zones that can be set according to an individual's personal best peak-flow reading. Peak flow meters are suitable for adults and children and can be used in hospitals, respiratory clinics, general practice, schools, sports medicine and home-care environments. Key Features - Measures Peak Expiratory Flow Rate (PEFR/PEF) - Useful for routine asthma monitoring - Portable handheld design - Easy-to-read graduated scale - Color-coded asthma management zones on applicable models - Adjustable zone markers - Suitable for adults and children - No electricity or batteries required - Reusable design - Lightweight and easy to carry - Simple manual operation - Suitable for home and clinical use - Helps users track changes in respiratory airflow
