Abstract

In-hospital cardiac arrest (IHCA) is a major cause of death among patients. Extensive research has been performed regarding out-of-hospital cardiac arrest (OHCA), and efforts to improve prognosis have led to a dramatic increase in survival. However, IHCA has not been widely studied, and even basic data, such as incidence, has only been covered in a few reports. Research on cardiac arrest and cardiopulmonary resuscitation (CPR) has considerably increased in recent decades, and international guidelines for resuscitation have been implemented and have undergone several changes.
