无创性机械通气的目标在于避免气管切开或插管,改变“传统机械通气”原理,更符合生理状态而达到机械通气目的。我们采用压力支持辅助通气、双水平气道正压(Bipap)呼吸机,早期治疗慢性呼吸衰竭25例,提高了呼吸衰竭治疗的成功率,现报告如下。1　资料与方法1.1　病例选择:1994年4 The goal of non-invasive mechanical ventilation is to avoid tracheotomy or intubation, to change the “traditional mechanical ventilation” principle, more in line with the physiological state to achieve the purpose of mechanical ventilation. We use pressure to support assisted ventilation, Bipap ventilator, early treatment of chronic respiratory failure in 25 cases, improve the success rate of respiratory failure treatment, are as follows. 1 Materials and Methods 1.1 Case Selection: 1994 4
