A method of producing medical oxygen gas clearly and unambiguously standardized. In  stated that the medical oxygen gas – is product obtained from the air by low-temperature distillation method.
Medical oxygen gas in cylinders can be produced by two technological schemes:
- Compression and gasification of liquid medical oxygen in the air separation unit and filling of cylinders;
- Compression and gasification of liquid medical oxygen in evaporators connected to storage tank unit and filling of cylinders.
