New Method for Oxygen Therapy in the Home Using an Oxygen Concentrator

Patients with pulmonary hypertension due to chronic bronchitis may improve during long-term treatment with oxygen. The methods of administration which are currently available are expensive and present practical difficulties. The Rimer-Birlec domiciliary oxygen concentrator produces an oxygen concentration of 92% at a flow of 21./min. It has been used successfully in a patient's home but further use will require an increase in mechanical reliability and a decrease in noise. In view of its convenience and the economic advantages the oxygen concentrator is an important advance in treatment with oxygen and could prove to be the method of choice in the home.
