Woman reading with Freestyle Family POC
The FreeStyle portable oxygen concentrator (POC) makes its own oxygen in a compact package up to a 3-setting. Capable of producing up to 1,000 mL/min, the FreeStyle 5 has the highest oxygen output of any wearable POC on the market and offers 5 pulse setting options. Both POCs utilize a uniquely efficient flexible pulse-flow delivery system which enables patients to be as active as possible.

New carrying bags for FreeStyle POCs are now available! They are more durable due to their robust design. A side pocket was added to hold the External Power Cartridge and back pocket for additional items. The option of a carrying handle, shoulder strap, or backpack harness gives patients multiple mobility options for portability.
FreeStyle & FreeStyle 5 are equipped with UltraSense™ technology, which provides a more sensitive pulse dose delivery than competitor devices, even those that include a “sleep mode” setting. The advanced intelligence built into the microprocessor of the FreeStyle family ensures fast, reliable pulse dose delivery in the first phase of inhalation, when the highest levels of gas exchange are occurring in the lungs. This gives providers and patients alike the peace-of-mind that with UltraSense, patients are reliably receiving the oxygen they need, when they need it most. Also, unlike any other POC on the market, UltraSense technology delivers a reliable pulse dose even when operated with up to 25 ft (7.62 m) of tubing, allowing patients to go the distance with FreeStyle.
The internal battery enables up to 3 or 3½ hours of use between recharges. When more time is needed away from an available power source for extended activity, the optional External Battery Cartridge or AirBelt™ are there to provide hours of extended battery duration. These each connect easily to either unit and depending on the setting, can provide up to seven or ten hours of ambulation between recharges.
With these units, oxygen users can stay active and even enjoy the added benefits of the FAA-approved FreeStyle units during extended travel.
