Exercising can also help people strengthen their breathing muscles. One of the most important things people can do to improve their peak flow rates is to quit smoking. With a peak flow meter, the individual records their measurements, and there is no clip on the nose. With spirometry, a healthcare professional clips the person’s nose shut, and a machine records the readings. A peak flow meter is generally for home use. The most significant difference is that a medical professional typically uses a spirometer to diagnose respiratory problems, such as asthma and COPD and monitor the effectiveness of treatment plans. Is there a difference between a peak flow meter and a spirometer? Then they can work with their healthcare professionals to make helpful changes before problems get worse. Regular measurements help people learn what is best for them. An individual’s peak flow measurements can also change throughout the day or in response to specific events. For example, younger, taller people tend to have higher readings. The typical peak flow measurement is between 400–700 liters per minute for adults.Īge, gender, and height affect what is normal or “good” for an individual. The following are common questions and answers about peak flow meters: What does a peak flow meter measure?Ī peak flow meter measures how forcefully someone can push air out of their lungs.

Recognizing the signs of an asthma attack through peak flow monitoring alongside following an asthma action plan can prevent symptoms from becoming severe. The study also indicated that people with poorly controlled asthma had fluctuations in PEFR even without reported asthma symptoms. The researchers found that some people incorrectly perceived their symptoms as mild, even with significant airway obstruction. Researchers analyzed the relationship between changes in peak flow measurements and the participants’ asthma symptoms. In an older 2012 study, 53 people with asthma recorded their symptoms and peak flow measurements twice daily for 274 days. In some cases, a decrease in PEFR is an early sign of an impending asthma attack. Regular monitoring with a peak flow meter can help people detect changes in their airways before other symptoms start. Weather, exposure to allergens, infection, or even exercise can all affect asthma symptoms. The PEFR often changes in response to a flare-up of asthma. People with asthma may develop narrowing of the airways, which lowers the amount of air they can exhale.
