What does PEFR stand for?

What does PEFR stand for?

• A. Pulmonic expiratory flow rate
• B. Peak expiratory flow rate
• C. Pulmonary effort flow rate
• D. Peak enhancement flow rate

Answer: (B)

Peak expiratory flow rate is a crucial measure in pulmonary medicine that indicates how fast a person can exhale air from their lungs after taking a deep breath. It is an important indicator of respiratory function and can help evaluate conditions like asthma or chronic obstructive pulmonary disease (COPD). The value is generally determined using a peak flow meter, which provides a numerical representation of the maximum speed of expiration, reflecting the state of the airways. A lower than normal PEFR can signal airway constriction or obstruction, making it a valuable tool for monitoring changes in respiratory health and guiding treatment plans. Other choices do not accurately define the term associated with pulmonary function testing. While they may contain relevant words related to breathing or airflow, they lack the specificity and established usage of "peak expiratory flow rate" in clinical practice. This concept is widely recognized and utilized in both clinical assessment and patient education for managing respiratory conditions.
