peak flow meters

A peak flow meter is a portable device that measures how quickly air can be expelled from your lungs, specifically your peak expiratory flow rate (PEFR). It's commonly used by people with asthma to monitor their lung health and identify early signs of worsening symptoms. To use it, you take a deep breath, place the device in your mouth, and blow out as hard and fast as possible. Regular measurements help track your lung function over time, enabling you and your healthcare provider to manage your condition effectively and prevent asthma attacks.
