The blue code is intended to ensure the successful resuscitation of patients with impaired or disappearing life symptoms and in need of urgent basic life support by trained personnel. Therefore, the blue code status and the procedure to be followed are much more urgent and important than others. Since it is not clear when the event will take place, it is necessary to be prepared at any time. The arrest of vital functions can be in the wards or in the departments such as radiology unit, polyclinics, even the refectory or the maintenance department. Since there are no doctors or nurses in such administrative units, calls from these places are much more important. For this reason, blue code calls (like all other color code calls) can be made not only in clinics, but also in any unit of our hospitals (including the additional building).
