A review of the largest observational studies on post-ICU weaning from prolonged mechanical ventilation yields evidence that more than half of such patients can be successfully liberated from mechanical ventilation. Success is likely to fall within a 3-month window, with late successes and partial ventilator independence still possible thereafter. There is a uniformity of practice in finishing difficult weaning with self-breathing trials of increasing duration.
一项针对重症监护病房（ICU）中长时间机械通气后脱机的最大规模观察性研究综述表明，超过半数的此类患者能够成功脱离机械通气。成功脱机可能在3个月内实现，此后仍有可能出现较晚成功脱机以及部分依赖呼吸机的情况。在通过逐渐延长自主呼吸试验来完成困难脱机方面，存在实践上的一致性。
