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.

A respiration system is provided with a container (1) in which, by an exothermic chemical reaction of a reaction material, CO.sub.2 is removed from the respiration air or oxygen is generated, and with an indicator of the consumption of the reaction material. The consumption indicator has a predetermined amount (7) of material which can be melted by the reaction heat of the exothermic chemical reaction. The material is kept in thermal contact with the container interior in such a manner that a measurement of the total reaction heat, and thus the consumption of reactive material, can be read from the degree of melting of the meltable material.
