Abstract

Breathing apparatus having a heat sink (12) for cooling breathable gas in which the heat sink (12) comprises a material, for example an alloy or a wax, capable of undergoing at least one endothermic solid/solid or solid/liquid phase transition, with a phase transition temperature between 20°C and 100°C, preferably between 40°C and 80°C. The breathing apparatus may be of the closed loop, partially-closed-loop or open loop type.
