无创正压通气技术在急性左心衰竭患者中的应用研究

The applied experience of non-invasive positive pressure ventilation on patients with acute left cardiac insufficiency

目的:总结无创正压通气技术在急性左心衰竭患者中的应用经验。方法:对50例急性左心衰竭患者在对症治疗基础上实施无创正压通气,观察通气前及通气1 h,5 h临床症状及体征变化,比较生命体征及血气指标改善情况。结果:50例患者无创正压通气后临床症状、体征及生命体征、血气指标均明显改善。结论:无创正压通气用于急性左心衰竭可纠正患者缺氧状态,还能改善患者呼吸功能,有助于降低病死率及促进患者康复。

Objective： To summarize the experience of non-invasive positive pressure ventilation on patients with acute left ventricular failure . Methods .. Fifty cases withacute left ventricular failurev was cured by non - inva siva positive pressure ventilation based on symptomatic treatment. To observe clinical symptoms and signs before and after ventilation 1 h, 5 h. The signs and blood gases was compared. Results zThe clinical symptom,clinical sign,vital sign and blood gas index was improved obviously after non-invasive positive pressure ventilation. Conclusion：non-in- vasive positive pressure ventilation for patients with acute left ventricular failure can improve anaerobic condition,im- prove respiratory efficiency of patients ,help to reduce mortality and promote the rehabilitation of patients.
