机械呼吸机是治疗呼吸衰竭的主要设备之一,曾救回无数人的生命,但使用机械呼吸机可出现许多并发症。80年代,医疗界开始致力于降低医疗保健成本,使用机械呼吸机则十分昂贵。然而,近年来靠呼吸机维持生命的病人日趋增加。据报道,1979～1989年间美国依赖呼吸机病例每年增加50％,在医院的全部成本开支中,重症监护病房(ICU)占20％,相当于美国国民总值的0.8％,其中呼吸机的使用占据重要比重。
A mechanical ventilator is one of the main devices for treating respiratory failure. It has saved countless people’s lives, but there are many complications that can occur with mechanical ventilators. In the 1980s, the medical profession began to work to reduce the cost of health care, and the use of mechanical ventilators was very expensive. However, in recent years, the number of patients living on ventilators has increased. According to reports, the number of US-dependent ventilator cases increased by 50% every year from 1979 to 1989. In the hospital’s total cost expenditure, the intensive care unit (ICU) accounts for 20%, equivalent to 0.8% of the US GNI, in which the use of ventilators Occupy an important proportion.
