What's the FiO2 range?
21% to 100%, selected via the concentration dial.
What's the difference between the High Flow and Low Flow models?
High Flow delivers 2–100 L/min; Low Flow delivers 0–30 L/min. Choose based on the flow rate your respiratory device requires.
Does it warn if gas supply runs low?
Yes — it has an audible alarm for excessive pressure drop or gas supply depletion.
Can it feed more than one device at once?
An optional manifold outlet with 3 primary outlets is available for multi-device setups.
