Free AAMA Certified Medical Assistant (CMA) Practice Question
Peak expiratory flow rate (PEFR) is the maximum speed of expiration, measured during a pulmonary function test that can indicate the presence and severity of airway obstruction.
PEFR is indeed the maximum speed at which a person can exhale, which is measured during a spirometry test. It is crucial in assessing patients with asthma and other conditions that can lead to airway obstruction. The peak flow rate can reveal the severity of the obstruction and can be used to monitor the effectiveness of treatment. Other spirometry values are also measured, but PEFR specifically refers to the speed of the exhaled breath.
