Abstract: In this study, we have presented design and implementation of an Automatic Emergency Management System (AEMS) which can be used by hospitals for preliminary diagnosis of a patient`s condition in the emergency department. The AEMS consists of both hardware and software: the hardware has been designed to replace some medical equipment and software has been developed to compensate for human thinking and human experience. This system is expected to assist the emergency department staff in assigning priority levels to the patients and should bring about a quicker and more accurate patient`s assessment.
