在单人实施心肺复苏术 (CPR)过程中如果进行口对口人工呼吸 ,就必须暂时中断胸部按压。以往的资料表明 ,CPR期间冠状动脉 (冠脉 )灌流压会受到停止胸部按压的影响 ,恢复按压后冠脉灌流压恢复到中断按压前的水平可能需要一定时间。但目前尚不清楚中断胸部按压所造成的血流动力学
If mouth-to-mouth resuscitation is to be performed during CPR alone, chest compression must be interrupted temporarily. Previous data suggest that coronary perfusion pressure during coronary artery (coronary) perfusion may be affected by the closure of the thoracic pressure and restoration of the post-compression coronary perfusion pressure to the level before discontinuation of compression may take some time. However, it is unclear what the haemodynamics caused by the interruption of chest compressions
