Quizplus · Accepted Answer

Peak flow is the most useful pulmonary function test during an acute attack as it measures the maximum airflow during expiration, which is decreased during an asthma attack. It is a quick and easy measurement that can be done by the patient at home and can provide immediate information on the severity of the attack. Vital capacity and total lung capacity are better measurements for chronic lung diseases, while terminal flow is not a commonly used pulmonary function test.
