In order to improve the quality of care we provide to patients, medical trainees need to experience low incident, high mortality events in a safe learning environment. There is a selection bias for predisposing characteristics of health care providers, as most people who have pursued a career in medicine are motivated to learn how to manage medical emergencies. Resources have been traditionally enabled with conventional simulation centers or mobile simulation units. However, these are costly and difficult to access. The purpose of this study is to evaluate a mixed reality alternative to conventional simulation. The need for this is inherent in becoming a medical provider and use of these resources will improve health practices and health services.
