Venner a.p. Advance Video Laryngoscope

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to compare the Venner a.p. advance video laryngoscope to Miller laryngoscope during resuscitation with and without chest compressions.

Detailed Description
-----------------
Endotracheal intubation (ETI) is a life-saving procedure performed daily in emergency medicine. The European Resuscitation Council (ERC) 2010 cardiopulmonary resuscitation (CPR) guidelines suggest that intubators should be able to secure the airway without interrupting chest compression. However, ETI with uninterrupted chest compression in patients can be a very difficult skill to acquire.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to intubation | time from insertion of the blade to the first manual ventilation of the manikin´s lungs. If time of intubation is over than 60 seconds, attempt was recognized as failure. | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Success of intubation | effectiveness of the first, second and third intubation attempts and overall effectiveness of intubation by participants using four intubation devices. If the examinee failed at all attempts, the case was excluded from the time calculations. | 1 day | 
| POGO score | self-reported percentage of glottis opening (POGO) score | 1 day | 
| VAS score | participants were asked which method they would prefer in a real-life resuscitation. | 1 day | 
| Cormack-Lehan scale | self reported Cormack-Lehan scale during intubation | 1 day |
