What Is the FreeStyle Portable Oxygen Concentrator?

Oxygen concentrators were introduced in the mid-1970s and have become the most convenient, reliable source of
supplemental oxygen available today. Oxygen concentrators are the cost-effective, efficient, and safe alternative to
using high-pressure oxygen cylinders or liquid oxygen. An oxygen concentrator provides all the oxygen you need
with no cylinder or bottle deliveries required.
The air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% other gases. In the FreeStyle unit,
room air passes through a regenerative, adsorbent material called "molecular sieve." This material separates the
oxygen from the nitrogen. The result is a flow of high concentration oxygen delivered to the patient.
The size and weight of traditional oxygen concentrators have limited their portability. A person who needs oxygen
away from home or a hospital has used high-pressure oxygen cylinders and/or liquid oxygen. Oxygen conserving
3
devices (OCDs) have been used to increase the length of time that cylinders last. OCDs deliver oxygen only at the
beginning of inhalation, when oxygen is most beneficial. Using this technique, OCDs conserve oxygen.
FreeStyle uses traditional oxygen concentration technology and combines it with oxygen conserving technology. This
combination enables a significant reduction in the size of the oxygen concentrator and makes FreeStyle ultra-portable.
A typical oxygen concentrator weighs more than 50 pounds. In contrast, your FreeStyle concentrator weighs only
4.4 lbs (2kg).
