1. A device for humidifying breathing gas comprising:
a chamber for humidifying gas, the chamber having an inlet and an outlet, a chemical heating element disposed for thermal exchange with at least a part of the chamber, a trigger configured for activating the chemical heating element to generate heat, and a source of humidification fluid dispensable to the chamber, such that, in use, on activation the chemical heating element generates heat for heating of gas passing through the chamber from the inlet to the outlet and for heating of humidification fluid dispensed to the chamber to generate vapour, thereby promoting vapour uptake by the gas.
