Peak Expiratory Flow Meter

A Peak Expiratory Flow Meter is a handheld device that measures how quickly you can breathe out air after taking a deep breath. It helps monitor your lung function, especially for conditions like asthma. By blowing into the device, you get a numerical reading called the peak expiratory flow (PEF), which indicates how open your airways are. Regular use can help detect early signs of worsening lung issues, enabling timely management. It's simple to use and provides valuable information for you and your healthcare provider to track your respiratory health.
