Ventilator weaning protocols have the potential to expedite the weaning process and have been shown to reduce weaning time and the duration of mechanical ventilation in several studies. However, other studies have found no benefits from weaning protocols, and they may be particularly superfluous in highly staffed and structured intensive care units. Furthermore, for a protocol to improve outcomes, the clinicians must have a high rate of adherence to the protocol. Weaning protocols might improve patient care and outcomes, but their implementation should be based on local clinical characteristics and needs, and accompanied by an intensive education effort and measurement of adherence and outcomes.
撤机方案有可能加快撤机进程，并且多项研究表明，撤机方案能够缩短撤机时间和机械通气时长。然而，其他研究并未发现撤机方案有任何益处，而且在人员配备充足且结构规范的重症监护病房中，撤机方案可能尤其多余。此外，要使方案改善治疗效果，临床医生必须严格遵守该方案。撤机方案或许能改善患者护理及治疗效果，但其实施应基于当地临床特点和需求，并辅以强化教育工作以及对方案遵守情况和治疗效果的评估。
