A compound/ chemical which has oxygen rich free radical when activated by water to generate instantly, the medical grade oxygen without need for motors or electricity, which can be used to save lives in case of emergency. The complete kit comprises a free radical oxygen containing chemical, a water bottle, a nose mask, for plugging the oxygen to the patient in need. The source compound/ chemical is a crystalline adduct of Urea and H2O2, which when kept immersed in a catalytic material and when introduced with pre- measured volume of water instantly generates oxygen without need of pressure and electricity. In principle, this innovation works out a kit comprising of both containers, one with the chemical and the other with the water jar, enabling users to mix them immediately to get instant oxygen to address health issues such as nausea, breathlessness, suffocation, lack of oxygen in lungs, asthma, strokes caused due to breathlessness etc. This innovation addresses the need of oxygen at all times in any place, addressing the need of life saving gases, without going for costly infra-structure such as explosion proof rooms, electrical and gas piping systems, which are mandatory for oxygen lines generally seen in the medical industry. This innovation does away with all such infrastructure ad need, making the proposed ˜kit™ ensure that when used as per instructions, any life could be saved with instant release of oxygen from the so called/ proposed instant oxygen generating kit.
