Abstract
Various systems, devices, NO2 absorbents, NO2 scavengers and NO2 recuperator for generating nitric oxide are disclosed herein. According to one embodiment, an apparatus for converting nitrogen dioxide to nitric oxide can include a receptacle including an inlet, an outlet, a surface-active material coated with an aqueous solution of ascorbic acid and an absorbent wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material and the absorbent such that nitrogen dioxide in the gas flow is converted to nitric oxide.
Claims4
An apparatus for delivering nitric oxide to a patient, comprising:
- a gas source including nitrogen dioxide;
- a cartridge coupled to the gas source configured to convert nitrogen dioxide from the gas source into nitric oxide;
- a source of air downstream of the cartridge and configured to dilute a flow of gas that exited the cartridge;
- and
- at least one recuperator configured to further convert nitrogen dioxide into nitric oxide.
