Cannula – a plastic tube which attaches to an oxygen concentrator at one end and has a fitting to the patient’s mouth or nostrils at the other end
Capillaries – tiny blood vessels that line the walls of the alveoli and facilitate gas exchange in the lungs
Continuous flow – continuous flow oxygen concentrators emit a constant, steady supply of oxygen
COPD – Chronic Obstructive Pulmonary Disease
Diaphragm – a sheet of skeletal muscle below the rib cage, which contracts and expands as you breathe to make room for the breath in the lungs
Diaphragmatic breathing – a breathing technique which calls for contraction of the diaphragm on inhalation in order to allow more air into the lungs

Medical oxygen – any oxygen prescribed to aid oxygen deficiency, usually supplied in a pure form through an oxygen concentrator
Oxygen concentrator – a device which filters pure oxygen from the air into the patient’s mouth or nostrils
POC – portable oxygen concentrator
Pulmonary function tests (PFTs) – breathing tests run by healthcare professionals to assess lung function
Pulmonary artery – the artery that carries deoxygenated blood from the heart to the lungs
Pulmonary veins – the veins which carry oxygenated blood from the lungs to the heart
Pulmonary rehabilitation – long-term rehabilitation of the lungs which usually includes, but is not limited to, exercise training and breathing training
