When emergency codes are initiated as a call from anywhere in the hospital or health center, it indicates that there is an emergency at that point according to the content of the call. When the call is initiated, information is sent to the previously organised units and the hospital can intervene in the relevant event immediately. Emergency Codes are expressed in colors and a separate common number is determined for each color code by the National Color Codes standard. The most common codes are explained below: • Blue Code: Represents the presence of patients, relatives or hospital staff who need urgent medical attention. • White Code: It represents the existence of violence against hospital staff. • Pink Code: It represents the presence of an abduction attempt or abduction of an infant or child patient in hospital wards. • Red Code: It represents the presence of a fire situation in the hospital. In CALLVISION Emergency Code Systems, emergency code calls can be made from telephone, pagers, DECT devices and CALLVISION products. Emergency Code Systems can be integrated into any hospital environment. The Emergency Code is given from a phone number registered in the system and the Emergency Status is activated. The Emergency Code Server answers this call and processes the station information the call came from. Immediately after, it generates the emergency message and transmits this message to pagers and DECT devices. To cancel the emergency code, it is sufficient to dial the same number from the calling station.
