What is the FreeStyle Portable Oxygen Concentrator?
Oxygen concentrators were introduced in the mid-1970's and has become the most convenient, reliable
source of supplemental oxygen available today. Oxygen concentrators are the most cost-effective,
efficient, and safest 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.
FreeStyle combines advanced oxygen concentrator technology along with oxygen conserving technology
for the world's smallest and lightest portable oxygen concentrator at just 4.4 lb (2 kg). The FreeStyle
efficiently produces its own oxygen, and quickly delivers it as a pulse of oxygen when you breathe at the
very beginning of your inhalation. This eliminates the waste associated with a continuous flow oxygen
device that flows oxygen while you are exhaling. This pulsing of the oxygen is equivalent to continuous
flow. FreeStyle produces the equivalent of up to 3 LPM (liters per minute) in a lightweight package that can
be easily carried and used away from the home.
FreeStyle operates from four different power sources. (Refer to the Power Supplies section of this
manual.)
Operator Profile:
AirSep's Concentrators are intended to supply supplemental Oxygen to users suffering from
discomfort due to ailments which effect the efficiency of ones lungs to transfer the oxygen in air to
their bloodstream. POC's provide the convenience of using a non-delivery POC system rather than
delivery system (O2 tank) which makes the user relatively self-sufficient in terms of in-home use,
ambulation (both within and outside of the home) mobility and overall lifestyle. Oxygen Concentrator use
requires a physician's prescription, and is not intended for life support use.
Although Oxygen therapy can be prescribed for patients of all ages the typical oxygen therapy patient
is older than 65 years of age and suffers from Chronic Obstructive Pulmonary Disorder (COPD).
Patients typically have good cognitive abilities and must be able to communicate discomfort. If the
user is unable to communicate discomfort, or unable to read and understand the concentrator
labeling and instructions for use, then use is recommended only under the supervision of one who
can. If any discomfort is felt while using the concentrator, patients are advised to contact their
healthcare provider. Patients are also advised to have back-up oxygen available (i.e. cylinder oxygen)
in the event of a power outage or concentrator failure. There are no other unique skills or user
abilities required for concentrator use.
