Abstract

A high flow therapy system including a microprocessor, a heating element a non-sealing respiratory interface and a sensor is disclosed. The heating element is disposed in electrical communication with the microprocessor and is capable of heating a liquid to create a gas. The non-sealing respiratory interface is configured to deliver the gas to a patient.
