Abstract: This disclosure describes systems and methods for providing a high pressure controlled proportional assist ventilation breath type during ventilation of a patient. The disclosure describes a novel breath type that reduces ventilator support (or a percent support setting) based on the occurrence of a predetermined number of high pressure alarms.

Abstract: A method of method of high flow oxygen therapy (HFOT) and carbon dioxide (CO2) monitoring includes delivering high flow oxygen therapy (HFOT) via a central lumen of a nasal cannula, the nasal cannula comprising a proximal end, a distal end positioned within a pharynx region of a patient's airway, and the central lumen and a sampling lumen formed within a wall of the nasal cannula. The method also includes receiving sampled exhaled breath of the patient via the sampling lumen at a CO2 monitor, wherein the sampling lumen is configured to sample the exhaled breath at the pharynx region through the CO2-permeable membrane and direct the sampled exhaled breath to a CO2 monitor fluidly coupled to the sampling lumen and determining a level of CO2 in the exhaled breath using the CO2 monitor.

Abstract: The present application describes a previous mode button that allows a clinician to select any previously administered ventilation mode for a patient such that the previously input ventilation parameters for the selected ventilation mode will be used during ventilation. Upon receiving the selection of the previous mode button, a first stored previous mode and first ventilation parameters associated with the first stored previous mode are displayed. A determination is then made as to whether the displayed first stored previous mode is an appropriate mode. If the displayed first stored previous mode is an appropriate mode, ventilation is administered using the first stored previous mode and first ventilation parameters. If a determination is made that the first stored previous mode is not appropriate, a second stored previous mode is retrieved and displayed.
