SYSTEM AND METHOD FOR HIGH FLOW OXYGEN THERAPY

A method of method of high flow oxygen therapy (HFOT) and carbon dioxide (CO) 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 COmonitor, 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 COmonitor fluidly coupled to the sampling lumen and determining a level of COin the exhaled breath using the COmonitor. 1. A method of high flow oxygen therapy (HFOT) and carbon dioxide (CO) monitoring comprising:{'sub': 2', '2', '2, "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 further comprising an inflatable cuff coupled to an exterior wall of the nasal cannula to anchor the distal end within the pharynx region and a sampling lumen formed within a wall of the nasal cannula, the sampling lumen terminating in a carbon dioxide (CO) permeable membrane positioned at or near the distal end of the nasal cannula, and wherein the CO-permeable membrane is selectively permeable to COrelative to oxygen;"}{'sub': 2', '2', '2, 'receiving sampled exhaled breath of the patient via the sampling lumen at a COmonitor, wherein the sampling lumen is configured to sample the exhaled breath at the pharynx region through the CO-permeable membrane and direct the sampled exhaled breath to a COmonitor fluidly coupled to the sampling lumen; and'}{'sub': 2', '2, 'determining a level of COin the exhaled breath using the COmonitor.'}2.

TUBE POSITION MONITORING SYSTEM

A position monitoring system is provided that includes a tracheal tube having a distal portion with a radiopaque indicator. The tracheal tube is configured to be positioned within an airway of a patient. The position monitoring system also includes an external sensor configured to be positioned on an external surface of the patient. The external sensor includes an emitter configured to transmit energy into the patient and toward the distal portion and a detector configured to receive a reflected portion of the energy to permit identification of a position of the distal portion. The position monitoring system, in certain embodiments, further includes a video laryngoscope communicatively coupled to the external sensor. The video laryngoscope includes a display and a processor, and the processor is configured to instruct the display to present an indication of the position of the distal portion based on feedback from the detector. 1. A position monitoring system , comprising:a tracheal tube comprising a distal portion having a radiopaque indicator, wherein the tracheal tube is configured to be positioned within an airway of a patient; an emitter configured to transmit energy into the neck of the patient and toward the distal portion; and', 'a detector configured to receive a reflected portion of the energy to permit identification of a position of the distal portion; and, 'an external sensor configured to be positioned on an external surface of the patient, wherein the external sensor comprisesa video laryngoscope communicatively coupled to the external sensor, wherein the video laryngoscope comprises a display and a processor, and wherein the processor is configured to instruct the display to present an indication of the position of the distal portion based on feedback from the detector.2. The position monitoring system of claim 1 , wherein the processor is configured to:receive a signal indicative of the position of the distal portion from the detector;determine ...

System and method for high flow oxygen therapy

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.
