Early reperfusion of brain tissue at risk of injury is crucial for the treatment of acute ischemic stroke. The purpose of this study was to evaluate comfort levels in managing acute stroke patients with hypoxemia who required endotracheal intubation after multidisciplinary <i>in situ</i> simulation training and to shorten the door-to-image time.</p><p><strong>Methods: </strong>This quality improvement project utilized a comprehensive multidisciplinary <i>in situ</i> simulation exercise. A total of 53 participants completed the two-day <i>in situ</i> simulation training. The main outcome was the self-reported comfort levels of participants in managing acute stroke patients with hypoxemia requiring endotracheal intubation before and after simulation training. A 5-point Likert scale was used to measure participant comfort. A paired-sample <i>t</i>-test was used to compare the mean self-reported comfort scores of participants, as well as the endotracheal intubation time and door-to-image time on the first and second days of <i>in situ</i> simulation training.
