Abstract

A humidifier and humidity sensor used with a breathing assistance apparatus. The humidity sensor can sense absolute humidity, relative humidity and/or temperature at both the patient end and humidifier end. The humidifier can also control independently the humidity and temperature of the gases. Further, a chamber manifold can facilitate easy connection of the humidifier to various outlets, inlets and sensors. A heated conduit can provide a more effective temperature profile along its length.
