Peak Expiratory Flow Rate Test

The Peak Expiratory Flow Rate (PEFR) test measures how fast you can exhale air from your lungs. Using a handheld device called a peak flow meter, you take a deep breath and then blow out as hard and fast as you can. The meter gives a reading of your peak flow rate, indicating how well your lungs are functioning. This test is especially useful for individuals with asthma or other respiratory conditions, as it helps monitor lung health and can signal when to seek medical help. Regular monitoring can assist in managing symptoms and preventing asthma attacks.
