目的:观察冠心病致急性左心衰竭经无创正压通气治疗的临床疗效。方法:对27例冠心病致急性左心衰竭患者在常规治疗下不能有效改善低氧血症时,使用双水平正压通气(BiPAP)治疗,观察治疗前、后临床症状、体征的变化。结果:24例患者在无创机械通气后呼吸困难明显减轻;血气分析结果动脉pH、氧分压(PaO2)、二氧化碳分压(PaCO2)、心率(HR)、呼吸频率(RR)、收缩压(SBP)较治疗前明显改善;患者的症状和体征也明显改善。结论:无创BiPAP可明显改善冠心病致急性左心衰竭患者低氧血症,提高冠心病致急性左心衰竭的抢救成功率。
Objective: To observe the clinical effect of noninvasive positive pressure ventilation in treating acute left heart failure caused by coronary heart disease. Methods: 27 patients with acute left heart failure with coronary heart disease were treated with bi-level positive pressure ventilation (BiPAP). The clinical symptoms and signs were observed before and after treatment. Results: The 24 patients had less dyspnea after noninvasive mechanical ventilation. The blood gas analysis showed that arterial pH, PaO2, PaCO2, HR, SBP, SBP ) Than before treatment significantly improved; patients with symptoms and signs also significantly improved. Conclusion: Noninvasive BiPAP can significantly improve hypoxemia in patients with acute left heart failure caused by coronary heart disease and improve the success rate of rescue of acute left heart failure caused by coronary heart disease.
