Expiration Breathing air out of the lungs (exhaling).
Respiratory Rate The number of breaths a person takes per minute.
Pulse Oximetry A test that measures how much oxygen is in the blood using a small clip on your finger.
Peak Expiratory Flow (PEF) The fastest speed air comes out of your lungs when you blow out.
Peak Expiratory Flow Rate (PEFR) A measurement of how fast you can blow air out of your lungs.
Forced Expiratory Volume (FEV1) The amount of air you can force out of your lungs in one second.
Bronchodilator A medicine that relaxes and opens the airways to help you breathe easier.

Oblique Fissure A line that separates the upper and lower lobes of the lungs.
Diaphragm A large muscle under the lungs that helps you breathe.
Cartilaginous Rings Rings of cartilage that keep the trachea open so air can pass through.
