Intubation During Cardiopulmonary Resuscitation

Study Overview
=================
Brief Summary
-----------------
The aim of the study was to compare the intubation time and effectiveness, the grade of larynx visibility, and the ease of intubation in adults performed by nurses using 4 devices: a Macintosh blade laryngoscope (MAC), and a TruView EVO2 (EVO2), TruView EVO2 PCD (PCD), and ETView SL (ETView) laryngoscope, in simulated CPR settings with and without CC.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| time to the first ventilation attempt |  | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
