简要总结
European Resuscitation Council (ERC) Guidelines for Resuscitation 2010 emphasize high quality chest compressions .They propose minor changes for pregnant women: manual left deviation of the uterus or a left-lateral incline of 15-30to alleviate pressure on the inferior vena cava. We will examine the performance of the Glidescope (GVL), the Pentax-AWS Airwayscope(AWS) and Macintosh laryngoscope (McL) for airway management during chest compressions on 15 and 30 degree left-lateral tilt (15 &30 LLT) custom-made hard wedges.

结局指标
主要结局
Time to intubation
时间窗: 1day
We will check the times from inserting blade to mouth to exposing vocal cord and from exposing vocal cord to first ambu-bagging.
Success rate of intubation
时间窗: 1day
Definition of failed intubation * Time to intubation is longer than 90 seconds. * Wrong placement of endotracheal tube (For example : Esophageal intubation etc.)
次要结局
- Laryngeal View during intubation(1day)
- The preference for laryngoscopes(1day)
