Benefits of the Freestyle for Oxygen Therapy Users

The CAIRE Freestyle Comfort POC offers significant advantages over traditional oxygen therapy methods. Tanks and cylinders restrict mobility, and compact portable oxygen can't match the Freestyle's performance.

Here are some of the top benefits of the CAIRE Freestyle Comfort portable oxygen concentrator:

Ultimate Portability

The Freestyle's compact size and featherlight weight allow you to carry it discretely in the included shoulder bag. The unit can be slipped under airline seats with ease to enable travel. Its portability grants you the flexibility to go anywhere and do anything while on oxygen therapy.

Uninterrupted Oxygen Supply

This POC never runs out of oxygen like small compressed oxygen canisters do. The Freestyle produces an uninterrupted supply of oxygen from the ambient air around you. As long as it has power via battery or AC outlet, you have access to oxygen.

Higher Oxygen Concentrations

Typical portable concentrators produce 90-95% oxygen but the Freestyle delivers 96+% oxygen purity levels at all settings. This helps maximize the benefits of supplemental oxygen therapy.

Intuitive Controls

Large touch buttons and a user-friendly interface make the Freestyle incredibly easy to operate. There are no complicated settings or maintenance required.

Whisper Quiet

You can hold conversations, watch TV, and sleep soundly while using the Freestyle. It produces only 39 dB on setting 2.

The Caire Freestyle POC provides the oxygen you need with the freedom you want. Contact your medical supply provider today to see if the Freestyle is right for you.

UltraSense Technology

UltraSense is a sensitive breath detection technology that ensures oxygen is delivered to you when you need it.

Understanding UltraSense™: Breathing Made Easier

When patients use oxygen concentrators, the timing of oxygen delivery is crucial. The natural inhalation and exhalation cycle typically lasts around three seconds. The key challenge for most oxygen concentrators is delivering oxygen precisely when the body needs it – during inhalation. If oxygen is delivered during exhalation, the body fails to absorb it efficiently, reducing its benefits and leading to physical exhaustion.

UltraSense™ solves this by detecting a patient’s natural breathing pattern and ensuring that oxygen is delivered in the first third of the breath. This timely delivery helps patients absorb more oxygen during each breath, reducing strain on the body and preventing the need for frequent rest breaks due to insufficient oxygen intake.

Why Timing Matters for Ambulating Patients

For patients using portable oxygen concentrators like the CAIRE Freestyle Comfort while walking or performing other physical activities, oxygen delivery timing becomes even more critical. As activity increases, so does the body’s demand for oxygen. If the POC does not synchronize with the patient’s breathing, oxygen may be wasted during exhalation, forcing the individual to rest, as their oxygen levels drop and their heart rate increases.

UltraSense™ ensures the concentrator stays calibrated to the patient's breathing rate, even during periods of physical exertion. This synchronization gives patients peace of mind, allowing them to stay active and mobile without constantly worrying about whether their oxygen device is performing optimally.

UltraSense™: Designed for Comfort and Confidence

With UltraSense™, patients can maintain an active lifestyle with confidence. The ability to walk, exercise, or perform daily tasks without needing frequent pauses is a game-changer for many individuals reliant on oxygen therapy. The CAIRE Freestyle Comfort’s UltraSense™ technology ensures optimal oxygen delivery, no matter the activity level, enabling patients to lead more fulfilling and independent lives.

In conclusion, the CAIRE Freestyle Comfort's UltraSense™ technology represents a significant advancement in portable oxygen concentrators, ensuring patients receive the oxygen they need when they need it most. Whether you are ambulating, exercising, or simply going about your daily routine, UltraSense™ guarantees that your oxygen concentrator will keep up with your every breath.

By utilizing this innovative technology, the CAIRE Freestyle Comfort delivers not just oxygen, but also the freedom to live a more active and worry-free life.


Key Points:

  • UltraSense™ Technology: Ensures oxygen is delivered during the first third of your breath, maximizing absorption.

  • Improved Oxygen Efficiency: Oxygen is provided when you’re inhaling, not exhaling, ensuring you get the most out of every breath.

  • Perfect for Active Users: The concentrator adjusts to your breathing rate, even when walking or performing physical tasks, helping you stay active.

  • Reduces Fatigue: By optimizing oxygen delivery, UltraSense™ helps prevent exhaustion and the need for frequent rest breaks.

  • Peace of Mind: The technology keeps your oxygen concentrator calibrated to your needs, providing reliable performance in any situation.
