Peak flow measurements, also known as peak expiratory flow rate (PEFR) measurements, are a simple and non-invasive method used to monitor and assess the function of the lungs. This technique is particularly valuable in the management of asthma and other respiratory conditions. The measurement involves the patient exhaling as forcefully and quickly as possible into a peak flow meter, which records the highest airflow rate achieved. The results are typically expressed in liters per minute (L/min).

Peak flow measurements are often used to track the severity of asthma symptoms and the effectiveness of treatment. A decrease in peak flow readings may indicate an exacerbation of asthma symptoms, while an increase may suggest improved lung function. These measurements are usually performed at home by the patient and recorded in a diary, which is then reviewed by a healthcare provider.

The American Thoracic Society and the European Respiratory Society have established guidelines for the use of peak flow meters. These guidelines recommend that peak flow measurements should be performed at least twice a day, with the results recorded in a diary. The diary should include the date, time, and the peak flow reading, as well as any symptoms experienced.

Peak flow measurements are a useful tool for asthma management, but they should be used in conjunction with other diagnostic tests and treatments. Regular monitoring of peak flow readings can help healthcare providers make informed decisions about treatment adjustments and can improve the overall management of asthma and other respiratory conditions.
