Smart Oxygen Delivery
The CAIRE FreeStyle Comfort® portable oxygen concentrator features smart technology to help ensure proper O2 saturation.
AutoDOSE. This proprietary safety feature helps ensure consistent oxygen delivery so there's never a gap in therapy. If no breath is detected for 15 seconds, the unit will pulse oxygen at 20 breaths per minute until it detects the user's breath and the "no breath alarm" resolves.
UltraSense. Sensitive breath detection technology helps ensure that oxygen is delivered exactly when it's needed, even if the breath becomes shallow. It detects the pressure change during the user's breath and releases the pulse of oxygen upon inhalation, when it is most readily absorbed.
MyCAIRE. This telehealth solution allows users to access their O2 therapy information 24/7, review the user manual, request service, and more.
