A humidifier and humidity sensor for use with a breathing assistance apparatus.
The humidity sensor senses absolute humidity, relative humidity and/or temperature
at both the patient end and humidifier end. The humidifier may also include provision
to both control independently the humidity and temperature of the gases. Further,
a chamber manifold facilitates easy connection of the humidifier to various outlets,
inlets and sensors. A heated conduit provides a more effective temperature profile
along its length.
