A peak flow meter or peak flow meter (PFM) is a device used to measure the volume of air a person breathes out as a measurement of pulmonary function. A peak
Peak Flow Testing a self-assessment you can do at home to evaluate lung function. The peak expiratory flow rate (PEFR) provides a reliable objective measure of airway function. Your doctor will go over how to use a peak flow meter, which involves taking a deep breath and blowing out as ...

(the largest amount of air that can be inhaled or exhaled), peak flow rate (which measures the fastest speed at which an individual can blow air out of their lungs), and forced expiratory volume (the largest amount of air that can be exhaled in one second). Once the doctor has tested...
Patients' peak inspiratory flow rate (PIFR) may help clinicians select an inhaler device. Objective To determine the proportion of patients with asthma who could generate correct PIFRs at different inhaler resistance settings. Methods During a UK asthma review service, patients' PIFR was checked at...
The peak flow (peak expiratory flow rate [PEFR]) is 40% of the personal best or less than 150 L. What is life theatening asthma? The breath sounds may be very difficult to hear, and no wheezing is apparent as the airflow is exceptionally limited. Which would you give first? bronchodi...
it is noteworthy that intramuscular glucocorticoids have a delayed onset of action of 12 to 36 hours. Patients meeting certain criteria such as a respiratory rate of 30 breaths per minute, a heart rate of more than 120 bpm, a continued peak flow of less than 50% predicted, oxygen saturation...
Home-monitoring of peak expiratory flow rate using the mini-Wright peak flow meter is a useful technique for determining whether or not unexplained respiratory symptoms are caused by asthma. It is of particular value when airflow obstruction cannot be demonstrated at the time of consultation.关键词...
Testing peak flow at rest (or baseline) and after exercise can be helpful, especially in young asthmatics who may experience only exercise-induced asthma. If the diagnosis is in doubt, a more formal lung function test may be conducted. Once a diagnosis of asthma is made, a patient can ...
