Abstract: Disclosed herein is a system for delivering a nitric oxide to a subject, wherein the system comprises: (a) a nitric oxide injection line configured to inject a first gas at an injection point into a breathing conduit comprising a breathing gas, wherein the first gas comprises a first amount of nitric oxide; (b) a sampling line configured to sample a second gas comprising a second amount of nitric oxide and the breathing gas at a sampling location between the injection point of the first gas and a subject and (c) a feedback-loop controller that is in communication with: (i) a nitric oxide set-point controller configured to set a nitric oxide set-point amount; (ii) a source configured to provide a third gas having a third amount of nitric oxide; and (iii) at least one sensor configured to measure the second amount of nitric oxide in the sampling line.

Abstract: A device and method for calibrating a delivery device includes providing a container A containing a nitrite, providing a container B containing an acid, releasing the contents of containers A and B, allowing the nitrite and acid to mix, waiting for a predetermined time, allowing air to combine with the mixture, and using NO and traces of NO2 to check and calibrate NO and NO2 sensors.

Abstract: Start-up protocols for a device and method for administering NO is described.

Abstract: A system for deliverying a therapeutic amount of nitric oxide can include a reservoir assembly, a gas supply, and a delivery conduit including a first cartridge, wherein the first cartridge can include a surface-activated material saturated with an aqueous solution of a reducing agent.

Abstract: A system for delivering a therapeutic amount of nitric oxide can include a reservoir containing a nitrogen dioxide source. A heating element can be configured to heat the reservoir, causing nitrogen dioxide vapor to exit the reservoir through a restrictor into a conduit. The nitrogen dioxide vapor can mix with gas from a gas supply, which can then flow to a cartridge that includes a surface-activated material saturated with an aqueous solution of a reducing agent. The cartridge can convert the nitrogen dioxide into nitric oxide.
