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.
