Successful cardiopulmonary resuscitation (CPR) requires the use of it as part of a system of care called the Chain of Survival (Figure 14). As with any chain, it is only as strong as its weakest link. Thus, everyone must strive to make sure each link is strong. For instance, community leaders can work to increase awareness of the signs and symptoms of cardiac arrest and make AEDs available in public places. EMS crews must stay abreast of updates and innovations in resuscitation and hone the skills required to deliver CPR quickly and effectively. Hospitals should be ready to receive patients in cardiac arrest and provide excellent care. Critical care and reperfusion centers should be staffed by experts and equipped with the latest technology. Because recovery from cardiac arrest continues long after the initial hospitalization, patients should have formal assessment and support for their physical, cognitive, and psychosocial needs.
