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.
