A system for the delivery of nitric oxide can include a first platform including a first source of nitric oxide, a second platform including a second source of a nitric oxide, a delivery line coupled to the first platform and the second platform, and a controller configured to operate the first platform and the second platform simultaneously. A method of delivering nitric oxide can include communicating a first gas including nitric oxide through a first platform to a delivery line, communicating a second gas including nitric oxide through a second platform to the delivery line, and delivering the first gas and the second gas to a mammal via a delivery line.
