Abstract
In the first part of this report, a conventional portable oxygen producing apparatus, Solid Oxygen System (Life Support Co. U.S.A.), was evaluated on two patients with chronic respiratory failure from the view-point of improving activities of daily life. The results were rather satisfactory except for the limitation of duration.
In the second part, a portable oxygen supplying apparatus invented by us was introduced. The point of our apparatus is a inflatable jacket. The jacket serves as an oxygen reservoir in normal atmospheric pressure. The oxygen is supplied to this jacket from a con-ventional portable high pressure oxygen cartridge. The patients may inspire at their own will the oxygen in normal pressure from within the jacket, for this simple device does not require ordinary complicated heavy pressure-ajusting valve.
