Abstract

Un mélange gazeux utilisé en thérapie hypoxique normobare est obtenu par l'appauvrissement en oxygène d'un gaz atmosphérique comprimé à un niveau ne dépassant pas 10 atm. L'organe de séparation de gaz comprend une pile de membranes polymères planes composées de résine thermoplastique dont la perméabilité à l'oxygène est comprise entre 0,5 et 1,5 x 10-10 ml.cm/cm2.s.cmHg. 20 à 60 % en poids de polysiloxane et d'huile hydrocarbure sont dispersés dans la résine avec laquelle ils sont compatibles à une température élevée.
