peak flow meter

A peak flow meter is a simple device used to measure how fast air can be exhaled from your lungs. It helps monitor breathing capacity, especially for people with respiratory conditions like asthma. By blowing into the meter, you get a numerical reading called the peak expiratory flow, which indicates how open your airways are. Regular use can help detect early signs of airway narrowing, allowing for prompt management before symptoms worsen. It's a handy tool for patients and healthcare providers to track lung function and adjust treatment plans if necessary.
