What is Normal PEF Range
Peak Expiratory Flow (PEF), likewise called Peak Expiratory Flow Rate (PEFR) is an individual’s maximum speed of expiration, as measured with a peak flow meter. This is a small, hand-held device utilized to keep an eye on a person’s ability to breathe out air. It measures the air flow through the bronchi of the lungs and hence the degree of obstruction in the air passages.
Peak flow readings are greater when we are well, and lower when the air passages are restricted. From changes in taped values, we may figure out lung functionality, severity of asthma symptoms, and treatment alternatives.
Measurement of PEFR needs some practise to correctly utilize a meter and the normal expected value depends upon a patient’s gender, age and height. It is classically reduced in obstructive lung disorders, such as Asthma, COPD or Cystic Fibrosis.
Due to the wide range of ‘normal’ worths and high degree of irregularity, peak flow is not the advised test to determine breathing disease. However, it can be beneficial in some scenarios to keep track of the seriousness of it or efficacy of treatment. It is important to utilize the exact same peak flow meter whenever to guarantee consistency of the readings.
Normal Peak Flow Test Range
The Normal value (Target value) for PEF differs according to gender, age and height. This chart can be used to read-off your Normal value. Enter this value in your “Target PEF.” information field.
Peak flow readings are often categorized into 3 zones of measurement according to the American Lung Association; green, yellow, and red. Medical professionals and health practitioners develop management plans based on the green-yellow-red zones.
Green Zone: 80 to 100 percent of the usual or normal peak flow readings are clear. A peak flow reading in the green zone indicates that the lung function management is under good control.
Yellow Zone: 50 to 79 percent of the usual or normal peak flow readings suggests care. It may imply breathing air passages are narrowing and additional medication may be required.
Red Zone: Less than 50 percent of the normal or normal peak flow readings. Shows a medical emergency. Severe airway narrowing might be taking place and instant action requires to be taken. This would normally include getting in touch with a medical professional or healthcare facility.
