Abstract
A respiratory therapy system configured to deliver gases to a patient can have a non-sealed gas flow generating arrangement configured to deliver a high flow of positive gas to an airway of a patient and a negative flow of gas away from an airway of the patient. The positive and negative flows of gas can be generated simultaneously. The flow of positive and negative gases reduces exhaled gases in anatomical dead spaces of the patient.
