Operation

The Sarco creates a low oxygen, low carbon dioxide environment with the use of nitrogen. The nitrogen is produced in the base.

Upon the push of the button inside the Sarco (no one external to the Sarco can start the flow of nitrogen), the nitrogen is released.

Nitrogen gas rapidly and invisibly enters the capsule, replacing the air with pure nitrogen gas.

The air is expelled via a one-way valve system which is located at the rear of the Sarco.

Nitrogen gas can be neither seen nor smelt. Nitrogen is a harmless, NOT a poisonous gas.

The air that we breathe is composed of around 21% oxygen and 70% nitrogen.

Death occurs because of the rapid lowering of the level of oxygen within the capsule, not from the nitrogen gas per se.

The user’s exhaled carbon dioxide is similarly displaced by the flow of the nitrogen gas into the capsule.
