Peak Flow Meter-BSMI
A peak flow meter is a lightweight, user-friendly instrument that gauges how well your lungs can expel air. The peak flow meter can measure the force of air in liters per minute and provide you with a measurement on a built-in numbered scale by blowing a short blast of air through a mouthpiece on one end. Your doctor might advise using a peak flow meter if you have asthma to monitor your asthma control.
By detecting airway narrowing even before you experience any symptoms, a peak flow meter used regularly can help you keep track of your asthma and give you time to change your medication or take other actions before your symptoms worsen. A peak flow meter can be useful for adults and children as young as 5.
