II. 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 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 22kg (50 lbs). In contrast, your FreeStyle
concentrator weighs only 2kg (4.4 lbs).
FreeStyle delivers a flow of oxygen up to an equivalent flow of 3 LPM (litres per minute)
in this lightweight package that can be easily carried and used away from home.
FreeStyle operates from four different power sources. (Refer to the Power Supplies
section of this manual.)
III. Important Safety Rules
Carefully review and familiarise yourself with the following important safety information
about the portable FreeStyle Oxygen Concentrator.
• In the event of an alarm or if you are experiencing any signs of discomfort, consult
your Equipment Provider and/or your doctor immediately.
• This unit is not to be used for life support. Geriatric, paediatric, or any other patients
unable to communicate discomfort while using this machine may require additional
monitoring. Patients with hearing and/or sight impairment(s) may need assistance
with monitoring alarms.
• When using FreeStyle in a car, boat, or other vehicle with the DC power supply, make
sure that the vehicle is started and running before connecting the FreeStyle unit. If
the FreeStyle unit is connected to the vehicle while starting it, jumping or charging
the vehicle may cause a need to reset the FreeStyle unit's DC power supply. If this
occurs, disconnect the DC power supply from the DC outlet, restart your vehicle, and
then reconnect your DC power supply into the DC outlet.
