Mechanical ventilation is an effective treatment for acute respiratory failure. Mechanical ventilation is used in patients without respiratory failure, during general anaesthesia, where respiratory depressant drugs are given to provide surgical relaxation. Typically, at the end of surgery and anaesthesia, neuromuscular blockade is reversed and mechanical ventilation terminated such that the awake and spontaneously breathing patient can be discharged safely to the recovery room.

机械通气是治疗急性呼吸衰竭的有效方法。机械通气用于全身麻醉期间无呼吸衰竭的患者，给予呼吸抑制药物以提供手术放松。通常，在手术和麻醉结束时，神经肌肉阻滞被逆转并终止机械通气，以便清醒且自主呼吸的患者可以安全地出院到恢复室。
