Tidal volume refers to the amount of air inhaled or exhaled during a normal breath and is typically not the primary focus in pulmonary function testing during a normal industrial physical. While it is a relevant term in respiratory physiology, the standard tests conducted in an industrial physical, such as measuring forced vital capacity, peak expiratory flow, and inspiratory reserve volume, are more directly aimed at assessing a person's lung health and capacity to perform work-related tasks.

In pulmonary function testing, forced vital capacity measures the maximum amount of air that can be forcefully exhaled after taking a deep breath, peak expiratory flow indicates the highest speed of expiration and helps gauge the airway functions, and inspiratory reserve volume looks at the additional air that can be inhaled after a normal inhalation. These metrics are critical for healthcare professionals to assess potential respiratory issues in an industrial setting, where exposure to harmful substances can be a concern.
