智能脱机模式在机械通气脱机阶段的应用

Use of computer-controlled ventilator weaning modes

脱机是从完全通气支持向自主呼吸转变的一个过程,不同的通气技术被用于患者的脱机,常用的脱机方法包括T型管自主呼吸实验、同步间歇指令通气（SIMV）以及压力支持通气（PSV）。它们各有优缺点。新的通气模式开始应用到机械通气的脱机阶段,它们包括适应性支持通气（ASV）模式、Automode模式、分钟指令通气模式（MMV）和Smartcare模式等。它们减轻了医务人员的工作负担,提高了脱机的效率。

Weaning from mechanical ventilation is a period of transition from total ventilatory support to spontaneous breathing. Different ventilatory techniques can be used to wean patients from mechanical ventilation. The usual methods of weaning from mechanical ventilation are T-piece trials, synchronized intermittent mandatory ventilation and pressure support ventilation. All have their advantages and disadvantages. New ventilator modes have been introduced to facilitate weaning. They include adaptive support ventilation, automode, mandatory minute ventilation and smartcare, They relieved the work of medicial care and improved the efficiency of weaning.
