[Legal social status of management with portable liquid oxygen devices in Germany]

This survey is based on three successful German sociolegal court proceedings instituted against relevant statutory medical cost bearers in respect of providing pulmonary patients with portable light-weight oxygen equipment. The sociolegally relevant indications for liquid oxygen treatment are described contrasting with conventional oxygen suppliers such as concentrators or steel flasks. Also detailed are the sociolegally appropriate prescription procedures for patients suffering from chronic respiratory insufficiency who can be mobilised by treatment with oxygen.
