Active hypoxia prevention

Our O2Guard is the world’s only system for active hypoxia prevention. Should the inspired oxygen level drop below 21%, the O2Guard automatically overrules the settings and increases the flow of oxygen and fresh air. The risk of hypoxia is minimized. [1]

The O2Guard is a standard feature on all our Flow Family anesthesia machines.
