Brief 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.

Detailed description

Materials 1. Sim Mom manikin (Laerdal, Stavanger, Norway) 2. Stryker ST104-747(Transport stretcher®, 760 x 2110 mm, 228 kg, Stryker Co., Kalamazoo, Michigan, US) 3.

Design outcomes

Primary

Measure	Time frame	Description
Time to intubation	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	1day	Definition of failed intubation * Time to intubation is longer than 90 seconds. * Wrong placement of endotracheal tube (For example : Esophageal intubation etc.)

Secondary

Measure	Time frame	Description
Laryngeal View during intubation	1day	We will record the best laryngeal View during intubation. We will record according to the Cormack-Lehane Grade system.
The preference for laryngoscopes	1day	1. The preference for laryngoscope regardless of tilting degree of wedges 2. The preference for laryngoscope in 15 degree left-lateral tilt situation . 3. 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)
