Does a peak flow meter measure lung capacity?

A peak flow meter is a portable, easy-to-use device that measures how well your lungs are able to expel air. By blowing a quick blast of air through a mouthpiece on one end, the peak flow meter can measure the force of air in liters per minute and give you a reading on a built-in numbered scale.

The highest peak flow reading for an individual occurs between the age of 30-40 years. A reading of 400- 600 l/min is considered normal. An individual suffering with asthma would have a lower reading of 200-400 l/min. Exercise can increase an individual’s peak flow reading.
