Abstract
Described are nasal cannulas that improve the precision of the delivered dose for nitric oxide therapy by reducing the dilution of nitric oxide. The nasal cannulas may reduce the total volume and potential for retrograde flow during nitric oxide therapy through the design of the specific dimensions of the flow path and/or having check valves in the nitric oxide delivery line and/or having a flapper or umbrella valve dedicated to nitric oxide delivery. The nasal cannulas may also use materials that limit oxygen diffusion through the cannula walls. The nosepiece for these cannulas may be manufactured by a molding technique.
