Question

Quizplus · Accepted Answer

A peak flow meter is specifically designed to measure the air flow during forced exhalation, which is useful for monitoring conditions such as asthma or chronic obstructive pulmonary disease (COPD). It is not used for measuring blood pressure or holding breath capacity. While it can give some indication of breathing capacity, it is primarily used for measuring external respiratory function.
