心肺复苏(CPR)存活率约为5～23％,大多为<15％,影响存活率的因素虽然比较多,但中心静脉血血氧含量可能对CPR的预后有参考意义。为此,作者对43例心脏骤停病人进行了观察。全部病人均作常规CPR,气管内插管,纯氧通气,于心跳骤停后第5、10、15min采中心静脉血作血气分析。此43例,男:女=27:16,存活超过24小时14例(33％),男性存活病人平均年 Cardiopulmonary resuscitation (CPR) survival rate of about 5 to 23%, mostly <15%, although the factors that affect the survival rate are more, but the central venous blood oxygen content may have a reference value for the prognosis of CPR. To this end, the authors of 43 cases of cardiac arrest patients were observed. All patients were routine CPR, endotracheal intubation, pure oxygen ventilation, in the first 5,10,15 min after cardiac arrest central venous blood for blood gas analysis. The 43 patients, male: female = 27: 16, survived more than 24 hours in 14 cases (33%), the average age of male survivors
