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.
在我们地区，家庭中最普遍的氧气输送方式是将气体储存在压力瓶中以及使用制氧机。这两种设备都只能在患者休息时使用。我们评估了一种新的家庭用液态氧输送系统，该系统配备了一个便携式装置，使患者在家外也能吸氧。巴塞罗那地区已安装了7台这样的设备，患者接受度很高，且没有技术问题。为了验证临床适用性，我们在基线条件下以及使用便携式供氧源吸氧时都进行了运动测试。同时持续测量氧合血红蛋白饱和度和步行距离。在所有患者中，步行过程中均记录到氧合血红蛋白饱和度显著下降，吸氧后得到纠正。便携式液态氧源是一种很好的家庭氧疗输送系统，可使患者全天吸氧，尤其是在运动期间。尽管液态氧的供应有限，但对于运动性低氧血症可通过吸氧纠正且希望积极参与社交生活的患者，仍应推荐使用。
