Objective: The number of admissions to emergency services has been increasing in recent years. Therefore, the waiting period of the patients who come with respiratory distress is prolonged due to the hospital's intensity. For this reason, the use of mechanical ventilation (MV) for respiratory support in emergency is also growing. However, data on MV training of emergency physicians are limited. Because of increment use in MV, training and planning on this subject need to be changed. In this study, we aimed to contribute to future regulations by measuring the MV knowledge of physicians in the emergency services.
