How can you use a spirometer to determine the volume of air you inhale on a normal or deep breath?

A spirometer measures the volume of air inhaled and exhaled during breathing. To determine the volume of air inhaled during a normal or deep breath, you would take a deep breath in through the spirometer's mouthpiece, ensuring a tight seal. The device records the amount of air inhaled, and this measurement can be read directly from the spirometer's scale or digital display. By comparing the values obtained during normal and deep breaths, you can assess the differences in lung capacity and airflow.
