![]() To generate adequate cardiac output and prevent complications of CC such as liver or stomach rupture, European Resuscitation Council guidelines 2020 and American Heart Association 2020 recommended that, irrespective of rescuers variables, CC depth should be at least 5 cm, but not greater than 6 cm. According to the cardiac pump theory, direct ventricular compression significantly results in cardiac output.ĭuring CPR, the effectiveness of CC depends on compression rate and depth. External CC generates forward blood flow of approximately one-third of the normal cardiac output by increasing intrathoracic pressure (thoracic pump theory) and directly squeezing the heart (cardiac pump theory). Previous findings suggested that the appropriate external CC during CPR improves high survival rates and favorable neurologic outcomes for patients with cardiac arrest. ![]() The six interdependent links in the chain of survival consist of early recognition of cardiac arrest and activation of the emergency team, early cardiopulmonary resuscitation ( CPR), rapid defibrillation, early advanced cardiac life support, advanced resuscitation by emergency medical services, post-cardiac arrest care, and recovery. The term ‘Chain of Survival’ is a series of critical actions that improve survival following cardiac arrest.
