Elderly patients with limited prognosis and limited activities are sufficiently supplied by oxygen concentrators with or without portable oxygen gas cylinders. Younger patients with promising life expectancy should be candidates for transtracheal catheter and for liquid oxygen with or without oxygen saving systems.
预后有限且活动受限的老年患者,无论有无便携式氧气瓶,使用氧气浓缩器就能获得充足的氧气供应。预期寿命较长的年轻患者,应考虑使用经气管导管以及配备或不配备氧气节省系统的液氧。
