A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber. When the valve is actuated, the aqueous solution flows from the reservoir through the internal chamber and into the reaction chamber. This flow washes the catalyst into the reaction chamber along with the aqueous solution. The solution and catalyst mix with the peroxide adduct and cause an oxygen-generating reaction.
