Indretning og fremgangsmåde til tilførsel af en gasformig blanding til en brugers respirationsveje

摘要

The probe or end fitting (2) of a respirator (1) is connected to a bottle (8) of a gaseous mixture containing nitrogen monoxide by a line (10) comprising a solenoid valve (18) steered (17) by a signal representing a supply (7, 15, 12) of a flow of respiratory mixture by the respirator (1). The plant is controlled so as to supply, for breathing in, a gaseous mixture including between 21 and 100 % of oxygen and between 10 and 50 ppm of nitrogen monoxide.
