摘要
呼吸机的脱机和撤离过程是一个重要的临床问题。呼吸机撤离是呼吸机由全部同期支持转为自主呼吸过程。在脱机过程中不必要的延迟会增加机械通气的复杂性,如肺炎或气道损伤,同时增加治疗的费用。撤机分为脱机和撤离人工气道,撤机参数对撤机后果预测的准确率不高,本文论述了对自主呼吸试验失败原因及实施自主呼吸方法以及完整呼吸机撤离过程。
The discontinuation or withdrawal process from mechanical ventilation is an important clinical issue. Ventilator weaning is a gradual reduction of ventilatory support and its replacement with spontaneous ventilation. Traditional predictors of weaning success have an understandably high false negative predictive rate. Unnecegsary delays in this discontinuation process increase the complication rate for mechanical ventilation（ eg, pneumonia or airway trauma） as well as the cost. As the conditions that warrantedplacing the patient on the ventilator stabilize and begin to resolve, attention should be placed on removing the ventilator as quickly as possible. This article address the following three issues： the unsuccessful cause of spontaneous breathing trial, The approach of spontaneous breathing trial and＇integrity withdrawl process.
