Thecartridge contains chemicals which absorb exhaled carbon dioxide and - in case of a KO2 apparatus - humidity andgenerates also oxygen.In case of a NaClO3 apparatus a chemical oxygen source (NaClO3 candle) generates the oxygen to be needed.In case of a compressed oxygen apparatus oxygen is fed into the circuit at a suitable point by means of a constantflow device or by a lung governed demand valve or by a suitable combination of both.The breathing gas flow may be of the pendulum or loop type and excess gas is ejected via a relief valve.5 Classification5.1 GeneralOxygen escape apparatus are classified according to their oxygen source and rated working duration in types andclasses.5.2 Types of oxygen escape apparatus¾ Type CNaClO3
