ABSTRACT:
A humidifier provides humidified gases to a patient. The humidifier is very compact, having a gases volume of the order of 60 mls. A microporous water compartment is provided perpendicular to the gases flow to ensure efficient humidification of the gases. Also, a combined temperature probe and heater supply connector is provided which only supplies energy to the heater in the water compartment when the gases temperature sensor is appropriately positioned in the humidifier gases passageway. This reduces the risk of gases at excessively high temperatures being supplies to the patient.
