<P> Oxygen may be used for patients requiring supplemental oxygen via mask . Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply , pressures are usually around 345 - 380 kPa ( 50 - 55 psi ) , or in the UK and Europe , 4 - 5 bar ( approximately 58 - 72 psi ) . This arrangement is described as a vacuum insulated evaporator ( VIE ) or bulk tank . In small medical centers with a low patient capacity , oxygen is usually supplied by a manifold of multiple high - pressure cylinders . In areas where a bulk system or high - pressure cylinder manifold is not suitable , oxygen may be supplied by an oxygen concentrator . However , on site production of oxygen is still a relatively new technology . </P>
