Question

Quizplus · Accepted Answer

Residual volume (the volume of air that remains in the lungs after maximum expiration) cannot be measured with a simple spirometer test as it requires more advanced equipment such as a body plethysmograph or gas dilution technique. The other options, tidal volume (the volume of air inhaled and exhaled during normal breathing), vital capacity (the maximum amount of air that can be exhaled after a maximum inhalation), and expiratory reserve volume (the amount of air that can be forcibly exhaled after a normal exhalation) can all be measured with a simple spirometer test.
