压力支持通气在呼吸衰竭治疗中的应用

Clinical application of pressure-support-ventilation in respiratory failure

对于8名不同病因所致呼吸衰竭患者,分别在病程的不同时期,应用了压力支持通气。与普通正压机械通气相比,适当应用压力支持通气可使最大吸气压力降低,减少气压损伤的发生机会,适于自主呼吸较稳定呼吸衰竭患者的治疗,同时也是一种较理想的撤离机械通气的手段。

8 patients with respiratory failure caused by different diseases were treated with pressuresuppoet-ventilation (PSV), in early mechanical ventilation or in the course of wearning of mechanical ventilation. Compared to conventional mechanical ventilation, PSV gives the patient more control over the ventilatory pattern and reduces the incidence of some complication due to mechanical ventilation.
