An economic appraisal of different methods of long-term treatment with oxygen in the home has shown that the oxygen concentrator is the cheapest and most convenient one. The only method at present generally available in the National Health Service, the use of small oxygen cylinders, is the most expensive and least convenient of those studied. There is need for a more flexible administrative system which will allow patients and the Health Service to benefit from the economies which are offered by technical advances.
一项关于家庭长期用氧不同治疗方法的经济学评估表明，氧气浓缩器是最便宜且最方便的。目前国民医疗服务体系中普遍可用的唯一方法，即使用小型氧气瓶，是所研究方法中最昂贵且最不方便的。需要一个更灵活的管理系统，使患者和医疗服务机构能够从技术进步带来的经济效益中受益。
