O2Guard - active hypoxia prevention

Unique O₂Guard
helps reduce risk for hypoxia

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] [2] 

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

See how the O₂Guard works

The video explains why there´s always a risk for hypoxia during low-flow anesthesia due to rebreathing, and how O2Guard works. Whereas conventional hypoxic guards only trigger an alarm, the O2Guard actively intervenes.



The O₂Guard is the only commercially available active inspired hypoxic guard.

3-step safety with O₂Guard

In three steps, the O2Guard automatically increases the fresh gas and O2 settings to ensure that hypoxic mixtures can never be delivered to the patient. If the inspired O2 level still does not increase, the system will be flushed with 100% O2.

More unique innovations for our anesthesia machines

With our flow anesthesia technology you can easily ensure the perfect flow for each patient, finetuning anaesthesia delivery in real time, breath by breath.
