The peak flow meter pulmonary function test measures ____________________________.
What is a peak flow test?The peak flow test measures how fast you can breathe out after you’ve taken a full breath in. Your peak flow score is sometimes called your peak expiratory flow (PEF). Show
 What’s it used for?
What happens during a peak flow test?You take the biggest breath in that you can. Then blow out as fast as you can, into a small, hand-held plastic tube called a peak flow meter. You don’t need to empty the lungs completely – just a short, sharp blow, as if you’re blowing out a candle. The measurement taken is called your peak flow. Each time you check your peak flow, you should do 3 blows, with a short rest in between the blows. The best of the 3 is the one that should be recorded. Your health care professional will make sure that your technique is correct, as this may affect the readings. What will the results look like?Peak flow scores will vary depending on your age, your height and whether you’re a man or a woman. The expected values are higher in younger people, taller people and men. Peak expiratory flow (PEF) is measured in litres per minute. Normal adult peak flow scores range between around 400 and 700 litres per minute, although scores in older women can be lower and still be normal. The most important thing is whether your score is normal for you. Health care professionals will be looking to compare your scores over time, to see if your results are going up or down. Your peak flow reading may vary through the day and night. The amount of variation is important as well as the pattern. Keeping track of your peak flow can help you spot when your symptoms are getting worse and when you need to take your reliever inhaler or get medical help.

When you hear ‘respiratory care and diagnostics’, a number of devices used in this field, in respiratory laboratories and clinics may come to mind. There are many devices that may be used for respiratory disease diagnosis or as monitoring tools to track trends in a patient’s lung function. Spirometers and peak flow meters are perhaps some of the most widely used devices when it comes to the diagnosis and management of common respiratory diseases such as asthma, COPD and cystic fibrosis. These two devices share the same basic principle of operation. Both involve the patient blowing into the device via a mouthpiece, followed by the calculation and display of key parametric indicators of lung function based on this air flow. Spirometers and peak flow meters, however, may differ with respect to technology, functional capacity and intended use. What is a peak flow meter?A peak flow meter is a relatively straightforward tool that measures a patient’s ‘Peak Expiratory Flow’ or ‘PEF’. The PEF is a measure of how fast you are able to forcefully exhale after full inhalation. The regular collection of a patient’s PEF can help determine if the airways of the patient are narrowing. The device is commonly used by asthma patients to help keep their asthma under control. PEF testing can be performed as a means of early detection of potential asthma attacks, when they feel their symptoms are becoming worse or to help decide whether rescue medication is necessary. It is important that patients consult their doctor about what their personal best PEF is or should be, to provide a point of reference for PEF tracking in disease management. What is a spirometer?Spirometry, the evaluation of lung function with a spirometer, is one of the simplest and most commonly applied pulmonary function tests. A spirometer assesses a patient’s lung function, however, it offers a larger set of parametric values regarding lung health than a peak flow meter does. Spirometry requires a patient to perform specific breathing maneuvers using a spirometer. Each breathing maneuver has a specific pattern of inspiration and/or expiration pattern that the patient must follow in order to obtain a particular set of information related to their lung function. Through the assessment of inspiratory and/or expiratory flows, a spirometer can help detect not only the type of respiratory disease (if any) present, but also the degree to which the disease has progressed. Spirometers are particularly useful in the diagnosis of diseases such as COPD where the disease remains largely asymptomatic until lung capacity has been irreversibly compromised. Spirometers are therefore powerful tools which aim:
Currently the state-of-the-art spirometers, peak flow meters, inhalers and other respiratory devices such as those in the Spirohome range are integrating the device with digital platforms that virtually connect patients and doctors. Now patients are capable of performing clinical-grade lung function tests in non-clinical settings such as their own homes, and are able to share their results immediately with their doctors over online platforms. What does a peak flow meter pulmonary function test measure?Peak flow measurement is a quick test to measure air flowing out of the lungs. The measurement is also called the peak expiratory flow rate (PEFR) or the peak expiratory flow (PEF). Peak flow measurement is mostly done by people who have asthma.
What does a peak flow meter measure quizlet?A peak flow meter allows you to measure day-to-day changes in your breathing.
What is recorded by a peak flow meter?A peak flow meter is a portable, inexpensive, hand-held device that measures your ability to push air out of your lungs. Air flow is measured by the amount of air that you can blow out in one "fast blast." Peak flow meters come in two ranges to measure the air pushed out of your lungs.
What does a peak flow Metre measure and how is it commonly used?The peak flow meter works by measuring how fast air comes out of the lungs when you exhale forcefully after inhaling fully. This measure is called a "peak expiratory flow," or "PEF." Keeping track of your PEF, is one way you can know if your symptoms of asthma are in control or worsening.
