The CAIRE FreeStyle® Comfort® is a premium, lightweight portable oxygen concentrator (POC) engineered specifically to maximize mobility and active lifestyles. Recognized for its distinct ergonomic shell, it is a pulse-dose-only unit built for oxygen users who want to run errands, travel, hike, and enjoy all-day freedom without being bogged down by a heavy machine.

Unlike blocky, square devices that bounce against your leg while walking, the FreeStyle Comfort features a unique, body-contoured profile designed to rest naturally against the curve of your hip.

Smart Oxygen Delivery Technology

The standout clinical advantage of the FreeStyle Comfort is its suite of automated, proprietary delivery features that ensure you stay saturated regardless of your activity level:

• UltraSense® Technology: Features an exceptionally sensitive breath detection trigger. It detects even the shallowest, weakest breaths (like those taken during sleep) to ensure oxygen is delivered at the exact moment inspiration begins.

• autoSAT® Technology: Adjusts oxygen bolus size dynamically based on your respiratory rate. If you speed up your pace while walking, the device automatically maintains a consistent volume of oxygen per minute.

• Auto-Dose Safety Mode: If the unit detects zero breath activity for 60 seconds (for example, if the nasal cannula slips out of place), it will automatically pulse oxygen at a standard rate of 18 breaths per minute to keep you safe until the cannula is adjusted.
