Which type of oxygen is supplied by an Aviox bottle?

• A. Supplemental oxygen
• B. Emergency oxygen
• C. Medical oxygen
• D. Cabin oxygen

Answer: (A)

A portable oxygen bottle like Aviox is used to provide extra oxygen to an individual to prevent hypoxia when the surrounding air doesn’t supply enough oxygen at altitude or during a medical situation. That makes it supplemental oxygen—the purpose is to augment what the person is breathing, not to supply the aircraft’s entire cabin or a medical therapy in a hospital setting.

Why this fits best: it’s designed for personal, portable, on-demand O2 delivery to help maintain adequate blood oxygen levels, rather than being part of the aircraft’s fixed emergency system or the cabin’s built-in oxygen supply, and it isn’t a hospital-grade medical oxygen intended for therapeutic treatment outside of those contexts.
