1769	2162	The automatic regulator on an on-demand oxygen system performs two key functions: it adjusts the air-to-oxygen mixture ratio according to altitude (higher altitudes require a richer oxygen mix to maintain adequate partial pressure), and it delivers oxygen only during inhalation, conserving the supply. This is far more efficient than continuous-flow systems.
1770	2163	- B describes a simple pressure reducer, not an automatic regulator. C and D describe partial functions but miss the altitude-dependent mixture adjustment and the on-demand delivery mechanism.
