目的探讨有创机械通气治疗急性危重心源性肺水肿的治疗效果。方法对82例急性危重型肺水肿患者,应用机械通气治疗,运用彩色超声仪记录正压通气时二尖瓣、三尖瓣、肺动脉瓣,主动脉瓣口的血流速度。结果急性危重心源性肺水肿患者通过机械通气,可迅速改善通气,纠正缺氧,心率、呼吸频率较机械通气前均有显著下降,动脉血气较机械通气前显著改善,机械通气期间未出现血流动力学恶化的情况。正压吸气末主动脉瓣血流速度最大,在呼气末速度逐渐减低,与呼气相相比,吸气相肺膨胀时左心功能增强。结论机械通气技术是急救急性肺水肿的重要手段之一,可改善患者的预后。
Objective To investigate the therapeutic effect of invasive mechanical ventilation on acute critical pulmonary edema. Methods A total of 82 patients with acute critical pulmonary edema were treated with mechanical ventilation. The velocities of mitral valve, tricuspid valve, pulmonary valve and aortic valve were recorded by color sonography. Results In patients with acute critical cardiopulmonary edema, mechanical ventilation improved the ventilation rate rapidly and corrected hypoxia. Heart rate and respiratory rate were significantly lower than those before mechanical ventilation. Arterial blood gas was significantly improved before mechanical ventilation. Blood was not detected during mechanical ventilation Flow dynamics worsened. Positive end-inspiratory aortic valve blood flow velocity maximum, gradually decreased in the end-expiratory phase, compared with the expiratory phase, inspiratory phase lung expansion left ventricular function enhanced. Conclusion Mechanical ventilation is one of the most important ways to rescue acute pulmonary edema, which can improve the prognosis of patients.
