摘要
本文观察高频喷射通气(HFJV)治疗50例慢阻肺Ⅱ型呼吸衰竭的疗效。50例患者随机分组,采用不同的通气参数,结果无论通气参数高低,HFJV 治疗后氧分压(PaO_2)均能明显上升,二氧化碳分压(PaCO_2)随频率和驱动压的增加也升高。提出HFJV 治疗慢阻肺Ⅱ型呼吸衰竭应选择适当的通气参数,并以较低参数为宜。
50 cases were random divided into groups and various ventilation parameters were used After HFJV,PaO_2 obviously rose,having noth-ing to do with ventilation parame-ters, but PaCO_2 rose along with frecuency and drivin pressure.It is suggested,that lower Ventil asion Parameters Should be select ed during HFJV for respiratory failure type Ⅱ due to COPD.
