无创通气治疗老年AECOPD急性呼吸衰竭疗效观察

目的 观察BiPAP呼吸机治疗老年AECOPD急性呼吸衰竭的疗效.方法 对60例老年急性呼吸衰竭患者进行双水平（BiPAP）呼吸机治疗,观察治疗前后血气及症状体征的变化.结果 BiPAP呼吸机治疗后HR（1 14±16）次,分,R（30±5）次,分,pH（7.23±0.03）mmHg,PaO2（54±7.2）mmHg,PaCO2（54±7.2）mmHg,SaO2（30（5）mmHg,HCO3（114±16）mmHg,较上机前各项指标均有明显改善,各组比较差异有显著性（P〈0.05）.结论 无创通气对大部分AECOPD合并呼吸衰竭的病人有效,需选择合适的适应症,必要时及时改用有创通气.

Efficacy of non-invasive ventilation for acute respiratory failure in elderly patients with AECOPD

Objective To explore the efficacy of BiPAP ventilator in the treatment of acute respiratory failure in elderly patients with AECOPD.Methods 60 elderly patients with acute respiratory failure were treated with double-level (BiPAP) ventilation.The changes in blood gas,symptoms,and signs were observed after treatment.Results After treatment,PaO2,SaO2,and pH increased,R,HR,PaCO2,and HCO3 decreased,and symptoms were improved in 42 of the patients.The remaining 18 required invasive ventilation because of therapy failure.Conclusions Non-invasive ventilation is effective in managing respiratory failure in most patients with AECOPD.Indications must be selected properly and invasive ventilation should be used if necessary.
