Abstract:
1. A method of reducing rainout in a breathing circuit having an inspiratory limb having an inlet adapted to receive a breathable gas and an outlet adapted to supply the breathable gas to a patient, the inspiratory limb including a first electrically energizable heater circuit extending substantially along the length of the inspiratory limb, and an expiratory limb with a second electrically energizable heater circuit extending substantially along the length of the expiratory limb, the method comprising: coupling a heated and humidified breathable gas to the inlet of the inspiratory limb to be supplied to the patient from the outlet of the inspiratory limb such that the heated and humidified breathable gas passes along the length of the inspiratory limb between the inlet and the outlet; and independently, selectively electrically energizing the first and second heater circuits as the heated and humidified breathable gas passes along the length of the inspriratory limb.
