Safety of Ambulatory Platform
The pocket-sized ambulatory platform consists of a base module comprising the air pump, heater and batteries, and a separate disposable delivery package which includes a small integrated liquid NO2 reservoir together with a cartridge. There are no gas cylinders. The cartridge has extra reserve capacity beyond the maximum amount of NO2 that can be stored in the reservoir. A second cartridge is built into the attached cannula just prior to inhalation by the patient, and provides 100% redundancy to the main cartridge, which already has extra reserve capacity. In addition to serving as a redundant cartridge, the second cartridge converts any NO2 that may have formed in the tubing back to nitric oxide.
