How you would use a spirometer to measure the tidal volume of a person?

To measure the tidal volume using a spirometer, the person would be instructed to breathe normally while sitting comfortably. The spirometer, which can be a handheld device or a more complex system, will capture and record the volume of air inhaled and exhaled with each breath. The tidal volume is determined by observing the volume measurement during these normal breaths, typically displayed on the spirometer's readout. This process allows for accurate assessment of the amount of air exchanged in each breath without any additional effort from the individual.
