Abstract

A portable, small footprint oxygen generating and rebreathing apparatus uses H2O2 and a catalyst to generate copious quantities of breathable oxygen, without producing toxic byproducts. In one embodiment, the present invention encompasses a portable oxygen supply device, with a hydrogen peroxide feedtank, decomposition chamber containing a metal oxide catalyst, and one or more supply lines to provide oxygen to the operator of the device. The rebreathing apparatus also provides for carbon dioxide removal from exhaled air.
