Visual Perception Exploration Using Eye-tracking Technology in a Cannot Intubate/Cannot Oxygenate Simulation

Study Overview
=================
Brief Summary
-----------------
Using eye-tracking technology, the aim of this observational study is to compare the visual interests between attending physicians and residents watching a Cannot Intubate/Cannot Oxygenate (CICO) scripted and simulated scenario

Detailed Description
-----------------
Attending physicians and residents, from the department of Anesthesiology at the Université de Montréal were recruited on a voluntary basis. A 13-minute video based on a suggested CICO algorithm from the Difficult Airway Society to manage unanticipated difficult intubation in adults (3) was produced at the University of Montreal Simulation Centre using high-fidelity settings. The scenario was about a patient, with a cervical collar, in the post-anesthesia care unit. Throughout the video, the patient presents increasing respiratory distress worsening to respiratory failure. The anesthesiologist fails to ventilate, intubate and insert a laryngeal mask leading to a cricothyroidotomy. All participants were looking at a screen on which the scenario was broadcast. The screen was equipped with TobiiEyeX®, an eye-tracking system that automatically aggregates gaze data.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difference between Time to First Fixation and Total View Duration of areas of interests. | The screen was equipped with TobiiEyeX®, an eye-tracking system that automatically aggregates gaze data. The display was divided in seven Areas of Interest (AOI). Data were collected using the Tobii Studio® program to obtain the total view duration (TVD) of the various AOIs. | The primary endpoint is collected during 15 minutes, throughout the viewing of the video by the participant |
