The present invention generally relates to, amongst other things, systems, devices, materials, and methods that can improve the accuracy and/or precision of nitric oxide therapy by, for example, reducing the dilution of inhaled nitric oxide (NO). As described herein, NO dilution can occur because of various factors. To reduce the dilution of an intended NO dose, various exemplary nasal cannulas, pneumatic configurations, methods of manufacturing, and methods of use, etc. are disclosed.
1. A nasal cannula for therapeutic gas delivered to a patient in need thereof, comprising: a first lumen, a second lumen, and a third lumen: the first lumen being a first therapeutic gas lumen for delivering a first therapeutic gas comprising nitric oxide to a patient in need thereof,the second lume
1. A nasal cannula for therapeutic gas delivered to a patient in need thereof, comprising: a first lumen, a second lumen, and a third lumen: the first lumen being a first therapeutic gas lumen for delivering a first therapeutic gas comprising nitric oxide to a patient in need thereof,the second lumen being a triggering lumen, andthe third lumen being a second therapeutic gas lumen for delivering a second therapeutic gas comprising oxygen to the patient; anda cannula nosepiece allowing separate flow paths to the patient for (i) the first therapeutic gas lumen, (ii) the triggering lumen, and (iii) the second therapeutic gas lumen; andwherein the first lumen has an inner diameter that is smaller than inner diameters of the second lumen and third lumen but larger than an inner diameter of the flow path for the first lumen at the cannula nosepiece. 2. The nasal cannula of claim 1, wherein the nasal cannula (i) reduces dilution of one or more of the first and second therapeutic gases delivered to the patient or (ii) is configured to be placed in fluid communication with at least one system to deliver one or more of the first and second therapeutic gases to the patient, or both. 3. The nasal cannula of claim 1, wherein the nasal cannula at least one of inhibits mixing of nitric oxide and oxygen and reduces delivery of nitrogen dioxide to the patient. 4. The nasal cannula of claim 1, wherein the nasal cannula delivers one or more of the first and second therapeutic gases to the patient for treatment of pulmonary hypertension. 5. The nasal cannula of claim 1, wherein the nasal cannula delivers one or more of the first and second therapeutic gases to the patient for treatment of at least one of pulmonary hypertension secondary to chronic obstructive pulmonary disease (COPD), pulmonary hypertension as pulmonary arterial hypertension (PAH), pulmonary hypertension secondary to idiopathic pulmonary fibrosis (IPF), and pulmonary hypertension secondary to sarcoidosis. 6. The nasal cannula of claim 1, wherein the first therapeutic gas lumen for delivering nitric oxide is about six feet to about eight feet in length having an inner diameter of about 0.01 inches to about 0.10 inches. 7. The nasal cannula of claim 1, wherein the cannula nosepiece comprises a nitric oxide flow path having a volume that is less than about 25% of a minimum pulse volume of the pulse of nitric oxide. 8. The nasal cannula of claim 1, wherein the cannula comprises a wall material having a low oxygen transmission rate that is between 0.001(cc)(mil)(24hrs)(100in2)(ATM)and10(cc)(mil)(24hrs)(100in2)(ATM). 9. The nasal cannula of claim 1, wherein the cannula is further comprising a fourth lumen: the fourth lumen being another first therapeutic gas lumen for delivering the first therapeutic gas to the patient; andwherein the first lumen delivers the first therapeutic gas to one nostril of the patient and the fourth lumen delivers the first therapeutic gas to another nostril of the patient. 10. The nasal cannula of claim 1, further comprising one or more of: (i) at least one check valve in fluid communication with the first therapeutic gas lumen, (ii) a cannula key, (iii) a scavenging material, and (iv) a flexible support bridge. 11. A nasal cannula for therapeutic gas delivered to a patient in need thereof, comprising: a first lumen, a second lumen, and a third lumen: the first lumen being a first therapeutic gas lumen for delivering a first therapeutic gas comprising nitric oxide to a patient,the second lumen being a triggering lumen for triggering release of a pulse of the first therapeutic gas, andthe third lumen being a second therapeutic gas lumen for delivering a second therapeutic gas comprising oxygen to the patient;the first therapeutic gas lumen, the triggering lumen, and the second therapeutic gas lumen aggregating at a cannula nosepiece, the cannula nosepiece allowing separate flow paths to the patient for each of the first therapeutic gas lumen, the triggering lumen, and the second therapeutic gas lumen; andthe first therapeutic gas lumen having an inner diameter that is (i) smaller than an inner diameter of the second therapeutic gas lumen and an inner diameter of the triggering lumen and (ii) larger than an inner diameter of the flow path for the first therapeutic gas lumen at the cannula nosepiece. 12. The nasal cannula of claim 11, wherein the nasal cannula (i) reduces dilution of one or more of the first and second therapeutic gases delivered to the patient or (ii) is configured to be placed in fluid communication with at least one system to deliver one or more of the first and second therapeutic gases to the patient, or both. 13. The nasal cannula of claim 11, wherein the nasal cannula at least one of inhibits mixing of nitric oxide and oxygen and reduces delivery of nitrogen dioxide to the patient. 14. The nasal cannula of claim 11, wherein the nasal cannula delivers one or more of the first and second therapeutic gases to the patient for treatment of pulmonary hypertension. 15. The nasal cannula of claim 11, wherein the nasal cannula delivers one or more of the first and second therapeutic gases to the patient for treatment of at least one of pulmonary hypertension secondary to chronic obstructive pulmonary disease (COPD), pulmonary hypertension as pulmonary arterial hypertension (PAH), pulmonary hypertension secondary to idiopathic pulmonary fibrosis (IPF), and pulmonary hypertension secondary to sarcoidosis. 16. The nasal cannula of claim 11, wherein the first therapeutic gas lumen for delivering nitric oxide is about six feet to about eight feet in length having an inner diameter of about 0.01 inches to about 0.10 inches. 17. The nasal cannula of claim 11, wherein the cannula nosepiece comprises a nitric oxide flow path having a volume that is less than about 25% of a minimum pulse volume of the pulse of nitric oxide. 18. The nasal cannula of claim 11, wherein the cannula comprises a wall material having a low oxygen transmission rate that is between 0.001(cc)(mil)(24hrs)(100in2)(ATM)and10(cc)(mil)(24hrs)(100in2)(ATM).
