机械呼吸是指应用呼吸机来辅助或改变气道压力,维持病人呼吸的一种治疗方法。其目的是提高肺泡通气量,减少死腔通气,改善通气/灌注比率失调,减低呼吸功率。此法适用于呼吸衰竭、严重肺水肿患者,亦可用于心肺复苏、手术中呼吸管理、心胸外科术后及胸脑外伤。 Mechanical breathing refers to the application of ventilator to assist or change the airway pressure, to maintain a patient’s breathing a treatment. Its purpose is to improve alveolar ventilation, reduce dead space ventilation, improve ventilatory / perfusion imbalance and reduce respiratory power. This method is suitable for respiratory failure, severe pulmonary edema patients, can also be used for cardiopulmonary resuscitation, respiratory management during surgery, cardiothoracic surgery and thoracic trauma.
