Claim Text:
1. A high flow therapy system for delivering pressurized, heated and humidified respiratory gas to an airway of a patient, the system comprising: a respiratory gas flow pathway for delivering the pressurized respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the pressurized respiratory gas is controlled by a microprocessor; a mixing area for mixing oxygen and air in the respiratory gas flow pathway; a humidification area for humidifying respiratory gas in the respiratory gas flow pathway; a heated delivery conduit for minimizing condensation of humidified respiratory gas; a pressure pathway for monitoring pressure of the airway of the patient and communicating the monitored pressure to the microprocessor; and, a sensor disposed in communication with the pressure pathway, the sensor further disposed in communication with the microprocessor and configured to measure pressure in the airway of the patient, wherein the system is adapted to pass exhaled gas of the patient by one of through and about the non-sealing respiratory interface to ambient atmosphere without passing the exhaled gas through a remainder of the system.
