Abstract (en)
[origin: WO9508360A1] A gas mixture used in normobaric hypoxia therapy is produced by oxygen depletion of atmospheric gas compressed up to 10 atm. The gas separation unit comprises a stack of flat polymeric membranes made of a thermoplastic resin having an oxygen permeability of 0.5 to 1.5 10<-10> ml.cm/cm<2>.s.cmHg. 20 to 60 % wt. of polysiloxane and hydrocarbon oil, which are compatible with this resin at an elevated temperature, are dispersed in the resin.
