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.

Abstract: Described are methods for safer nitric oxide delivery, as well as apparatuses for performing these methods. The methods may include detecting the presence or absence of a nasal cannula, and stopping the delivery of nitric oxide or providing an alert if the cannula is disconnected. The methods may also include purging the nasal cannula if it is reconnected after a disconnection or if it is replaced by a new cannula. Other methods pertain to automatic purging of the delivery conduit if the elapsed time between successive deliveries of therapeutic gas exceeds a predetermined period of time.
