Abstract：
:The most widespread types of oxygen delivery at home in our area are bottles where the gas is stored under pressure and concentrators. Both devices can only be used at rest. We have assessed a new system for the delivery of liquid oxygen to be used at home, provided with a portable unit which permits that the patients receive oxygen also outside their homes. Seven such devices have been implemented in the Barcelona area, with an excellent acceptance and without technical problems. To verify the clinical indication, exercise tests were carried out both in baseline conditions and receiving oxygen from the portable source. Oxyhemoglobin saturation and the walked distance were continuously measured. In all patients important drops in the saturation of oxyhemoglobin were recorded during walking, which was corrected with oxygen administration. Liquid oxygen with a portable source is a good delivery system for oxygen therapy at home, permitting to receive oxygen throughout the day, particularly during exercise. Although the availability of liquid oxygen is limited, it should be recommended to the patients in whom exercise hypoxemia is shown to be corrected and who desire an active social life.
