Stroke is the third-leading cause of death and the leading cause of long-term disability according to the American Heart Association. Decompression illness (DCI) can present as a neurological injury associated with scuba diving. Rapid recognition of and response to a suspected neurological injury, regardless of cause, can help convince the injured person of the need for emergency oxygen and help the responder monitor the injured person’s condition and report findings to emergency medical services (EMS).
