Significance of Peak Expiratory Flow Rate
Peak Expiratory Flow Rate (PEFR) is a critical measure of how quickly a person can exhale air, providing insights into lung function and respiratory health, particularly for asthma patients. It assesses the maximum speed of expiration and is essential for diagnosing and monitoring asthma and other respiratory conditions. PEFR is utilized to evaluate lung function before and after treatment interventions, highlighting its importance in managing respiratory health effectively. It also plays a role in recovery assessments for patients post-COVID-19.
