Weaning comprises 40 percent of the duration of mechanical ventilation. Protocols to reduce weaning time and to identify candidates at the earliest possible moment have been introduced to reduce complications and costs. Increased demand for mechanical ventilation, an increase in the number of patients requiring prolonged ventilation, and resource/staffing issues have created an environment where automated weaning may play a role. A number of closed loop techniques have been introduced since the early 1990s, with increasing sophistication. Preliminary research has demonstrated mixed results. Current systems continue to be evaluated in different patient populations and environments. Automated weaning is part of the ICU armamentarium, and identification of the patient populations most likely to benefit needs to be further defined.
撤机占机械通气时间的 40%。为了减少并发症和成本，已经引入了减少撤机时间和尽早识别候选者的方案。对机械通气的需求增加、需要长时间通气的患者数量增加以及资源/人员配备问题，创造了一个自动化撤机可能发挥作用的环境。自 20 世纪 90 年代初以来，已经引入了许多闭环技术，并且越来越复杂。初步研究表明结果喜忧参半。目前的系统仍在不同的患者人群和环境中进行评估。自动化撤机是 ICU 武器库的一部分，需要进一步确定最有可能受益的患者人群。
