Claims9
A respiratory system comprising:
- a humidifier system comprising an inlet for taking in a breathable gas and a humidification chamber connected to the inlet for heating and humidifying the breathable gas before delivery to a patient;
- a pre-conditioning system for pre-conditioning the breathable gas before entry into the humidification chamber in a controlled manner;
- a controller for controlling the respiratory system;
- a first dewpoint system for determining the dewpoint of the breathable gas in the inlet and communicating with the controller,
- a patient interface;
- a conduit connectable to the humidifier system and the patient interface for supplying the breathable gas to the patient interface;
- a heating system associated with the conduit for heating the breathable gas delivered from the humidifier system to the patient interface, the heating system comprising a heating element in communication with the controller;
- and
- at least one second dewpoint system for determining the dewpoint of the breathable gas in at least one part of the conduit between the humidifier and the patient interface;
- wherein the controller is provided for controlling the pre-conditioning system and the heating system associated with the conduit on the basis of dewpoint values determined by the first and second dewpoint systems.
