Frequently Asked Oxygen Concentrator Questions:1.What is Oxygen Therapy? Oxygen therapy is usually delivered as a gas through an oxygen source such as an oxygen concentrator or a cylinder. The oxygen is simply breathed by the patient via nasal cannula (nasal prongs) or through a mask that covers the nose and mouth. A nasal cannula is a two-pronged device that is inserted in the nostrils and is connected to the tubing having the oxygen. 2.How do I select a portable system?A portable oxygen system offers you with complete independence.
