This document discusses the assessment and care of patients experiencing behavioral emergencies. It outlines several causes of behavioral changes including medical conditions, substances, and psychological crises. When assessing a patient, EMTs should evaluate their mental status, speech, orientation, and risk of violence. Care involves maintaining distance, encouraging talking, and avoiding threats or arguments. Restraints may be needed if the patient is a danger, and should be done quickly with adequate help while avoiding positional asphyxia. Suicide risk factors and signs are also outlined.
