Tracking Lung Function: How to Measure and Interpret Peak Expiratory Flow Rate
Author(s): Sarkar Biswarti*
Lung health is a crucial aspect of overall well-being, as our respiratory system plays a vital role in supplying oxygen to the body. Monitoring lung
function is essential, especially for individuals with respiratory conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD), or those
at risk of lung-related problems. One valuable tool in assessing lung function is Peak Expiratory Flow Rate (PEFR). Peak expiratory flow rate is a
measure of how fast a person can exhale air from their lungs. It quantifies the maximum speed at which an individual can breathe out forcefully
after taking a deep breath in. PEFR is expressed in liters per minute (L/min) and is a fundamental tool in assessing and monitoring lung function.
PEFR is a simple and non-invasive test that measures the maximum speed at which a person can forcefully exhale air from their lungs. PEFR is
