Hospitals and Other Fields of Application

Hospitals, rehab-clinics, emergency services and registered doctors with own practices receive medical oxygen either in large quantities in liquid state by tank trucks or in compressed gas cylinders (single cylinders or cylinder bundles), if smaller quantities are required. 

Oxygen is either centrally provided via pipe systems and withdrawn in the hospital wards via quick couplings (wall outlets) or delivered directly to the patient by means of mobile compressed gas cylinders. The cylinder pressure (e.g. 200 bar) has to be reduced to a pressure suitable for the patients needs by means of pressure regulators or an innovative cylinder valve with permanently integrated pressure regulator and flow meter (medical device with CE-marking). 

Current applications are the HBO-Chambers (Hyperbaric Oxygenation), in which oxygen is administered under increased pressure. 

Nitrous oxide (N2O) existing in the atmosphere emanates from different sources. The main pollution of the atmosphere with nitrous oxide arises from fertilizers in agriculture. In relation to the total emission of nitrous oxide in the atmosphere, the share of medical nitrous oxide is less than 0.05%. Here it has to be considered that nitrous oxide enhances the greenhouse effect, however, without any influence on the ozone layer. 

Medical nitrous oxide is obtained by heating of ammonium nitrate
