What Spirometry Measures

The idea
Spirometry measures how much air a person can breathe out, and how fast.
In practice
The patient breathes through a mouthpiece connected to a device called a spirometer, which records the volume and speed of each breath.
Where people slip
The result depends on the patient's effort, which is why careful coaching matters so much.
