The mouthpiece (2) of a respirator (1) is connected to a bottle (8) of a gaseous mixture containing nitric oxide by a line (10) comprising an electrovalve (18) controlled (17) by a signal representing a supply (7, 15, 12) of a flow of respiratory mixture by the respirator (1). The installation is controlled so as to supply, upon inhalation, a gaseous mixture comprising between 21 and 100% of oxygen and between 10 and 50 ppm of nitric oxide.

A system for supplying gas to the respiratory ways of a patient, comprising: at least one source of a breathable oxygenated gas mixture under pressure; a source of nitric oxide under pressure; a gas conduit having an upstream portion connected to a respiratory device and a downstream portion adapted

A system for supplying gas to the respiratory ways of a patient, comprising: at least one source of a breathable oxygenated gas mixture under pressure; a source of nitric oxide under pressure; a gas conduit having an upstream portion connected to a respiratory device and a downstream portion adapted to be connected to the respiratory ways; a respiratory device connected to the sources of oxygenated gas mixture and of nitric oxide and including detection means for detecting inhalation phases of the patient and means for sequentially supplying to the gas conduit doses of said oxygenated gas mixture at a first point located upstream of the gas conduit and a controlled amount of nitric oxide at a second point located in the downstream portion of the conduit, upstream of the respiratory ways, and downstream of said first point, whereby premixing and oxidation of the nitric oxide with the oxygenated gas mixture is minimized before inhalation of the gas by the patient.
