Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to intubation	We will check the times from inserting blade to mouth to exposing vocal cord and from exposing vocal cord to first ambu-bagging.	1day	No
Primary	Success rate of intubation	Definition of failed intubation; Time to intubation is longer than 90 seconds.; Wrong placement of endotracheal tube (For example : Esophageal intubation etc.)	1day	No
Secondary	Laryngeal View during intubation	We will record the best laryngeal View during intubation. We will record according to the Cormack-Lehane Grade system.	1day	No
Secondary	The preference for laryngoscopes	The preference for laryngoscope regardless of tilting degree of wedges; The preference for laryngoscope in 15 degree left-lateral tilt situation .; The preference for laryngoscope in 30 degree left-lateral tilt situation . (Participants will select only 1 of 3 laryngoscopes and the preference will be displayed as histogram)	1day	No
