1. A respiratory apparatus, comprising:
a first gas inlet for supplying a first gas to the respiratory apparatus;
a second gas inlet connectable to a pressurized gas source to supply a pressurized gas;
a mixing chamber for mixing the first gas and the pressurized gas; and
a noise-damping member disposed downstream of the mixing chamber;
wherein the mixing chamber comprises a gas outlet for discharging a mixed stream of gas towards a humidifying chamber;
wherein the respiratory apparatus further comprises a flow sensor for determining a flow rate of the mixed stream of gas towards the humidifying chamber; and
wherein the noise-damping member is cylindrical, and has a cylindrical body insertable into the flow sensor and an end portion with a diameter greater than the diameter of the cylindrical body.
