Tap to reveal answer

Answer

Pulmonary function tests or spirometric tests are tests designed to measure a host of breathing functions. Since values vary depending on body position, time of day, and other factors, most metrics have a high tolerance for variance and typically require a person to score below 80% or above 120% of their expected values before a result is considered "abnormal". These tests are most often employed diagnostically, but may also be used to check up on the progress of a treatment program.

A laryngoscope is used to view the larynx and epiglottis, but does not provide quantitative functional data.
