4 — MN218-C4 A EnglishWhat is the Oxygen ConcentratorThe air we breathe contains approximately 21%oxygen, 78% nitrogen, and 1% other gasses. In theFreeStyle and FreeStyle 5, room air is drawn intothe machine through the air intake. It then passesthrough an adsorbent material called “molecularsieve”. This material separates the oxygen fromthe nitrogen and allows only the oxygen to passthrough. The result is a flow of high-concentrationoxygen delivered to the user.FreeStyle and FreeStyle 5 combine advancedoxygen concentrator and oxygen conservingtechnologies to create a portable device that allowsfor maximum portability and ambulation. TheirWhy Your Physician Prescribed OxygenMany people suffer from a variety of heart, lung,and other respiratory diseases.
