儿童心肺复苏期间与复苏后通气策略

Ventilation strategies during and after cardiopulmonary resuscitation in children

心肺复苏（cardiopulmonary resuscitation，CPR）期间，予以口对口送气或球囊面罩加压通气，通气频率12—20次／min。气管插管通气后通气频率8～10次／min。儿童胸外按压和通气比30：2（1人施救）或15：2（2人施救）较为合理。CPR后自主循环恢复，仍无自主呼吸或自主呼吸不规则、呼吸功能不全或部分患儿需要吸人高浓度氧，则需要机械通气。目前公认CPR后避免高氧和过度通气，并发急性肺损伤／急性呼吸窘迫综合征时采用肺保护通气策略。

During cardiopulmonary resuscitation （CPR）, ventilation is provided by either mouth-to- mouth or bag-mask technique,and give 12 to 20 times breaths per minute. Ventilation should deliver 8 to 10 times breaths per minute after endotracheal intubation. Compressionventilation ratio is 30：2 for one rescuer and 15：2 for two rescuers. After the return of spontaneous circulation, if no spontaneous breathing or irregu- lar, respiratory insufficiency, mechanical ventilation is required. High oxygen and excessive ventilation after CPR should be avoided. When acute lung injury or acute respiratory distress syndrome occurs after CPR, lung protective ventilation strategy is applicable.
