Rapid assessment of the maternal airway, breathing, and circulation and ensuring an adequate airway avoids maternal and fetal hypoxia. 快速评估母亲呼吸道、呼吸和循环,保证呼吸道通畅避免母亲和胎儿缺氧。
Objective : To investigate the clinical value of airway ( A ), breathing ( B ), circulation ( C ) three basic procedure in early stage of cardiac pulmonary resuscitation ( CPR ). 目的:评价早期心肺复苏(CPR)中A(气道)、B(呼吸)、C(循环)抢救步骤的价值。
Result The results demonstrated that heliox could reduce airway resistance, airway pressure and work of breathing, improve lung effective compliance, but had no effects on pulmonary circulation and systemic circulation. 结果Heliox可以迅速降低气道压力、气道阻力,降低呼吸功耗,提高肺顺应性;
