Nitrogen monoxide composition for use as a drug

A method for treating or preventing ischemia comprising administering to a patient by an intravascular route a gaseous mixture comprising nitric oxide (NO) and carbon dioxide (CO.sub.2), wherein the nitric oxide is present in an amount effective to treat or prevent ischemia. A gaseous mixture for treatment or prevention of ischemia comprising:

Injectable NO/CO.sub.2 gaseous mixture

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.

Nitric oxide ventilation arrangement and method

Process for preparing disilane, wherein a raw gas including monosilane, disilane, trisilane and impurities such as phosphine, hydrogen sulfide, arsine, disiloxane and higher siloxanes, undergoes a step of separation by distillation for the substantial elimination of the other compounds of silicon, except disiloxane, and the substantial elimination of phosphine, hydrogen sulfide and arsine impurities, wherein a final purification of the disilane takes place by selective adsorption on molecular sieves, in which one is a sieve of type 3 A and which is used for the elimination of the siloxanes and hydrogen sulfide and the other is a sieve of type 4 A for the elimination of phosphine and arsine.
