Abstract
The present invention provides a method and apparatus for reducing condensation in a respiratory circuit during a delivery of humidifying agent into the respiratory circuit. A first amount of humidification agent to a first volume of gas is delivered to a patient respiratory circuit during a patient inhalation cycle or immediately after a patient exhalation cycle, and the humidification agent or the first volume of gas is heated. Condensation is removed from the respiratory circuit at least in part by providing, during a patient exhalation cycle or immediately after a patient inhalation cycle, a second amount of the humidification agent to a second volume of gas being delivered from the gas source to the patient respiratory circuit, the second amount of the humidification agent being significantly less than the first amount of the humidification agent.
