Mechanical ventilation can provide life saving support to critically ill patients with respiratory failure. The implementation of appropriate monitoring techniques and an awareness of potential complications can increase the safety of mechanical ventilation. Several efficacious weaning methods can be utilized and none is clearly superior to the others. The improper use of any weaning technique can result in respiratory muscle fatigue delaying extubation. Determining patient suitability for extubation is an inexact science. The physical examination during a spontaneous breathing trial and the use of the rapid shallow breathing index can assist the clinician in the difficult decision as to the timing of extubation.
机械通气可为呼吸衰竭的重症患者提供挽救生命的支持。实施适当的监测技术并了解潜在并发症可提高机械通气的安全性。可采用几种有效的撤机方法，且没有一种方法明显优于其他方法。任何撤机技术使用不当都可能导致呼吸肌疲劳，延迟拔管。确定患者是否适合拔管是一门不精确的科学。自主呼吸试验期间的体格检查以及快速浅呼吸指数的使用可帮助临床医生做出关于拔管时机的艰难决策。
