Successful CPR requires the use of a CPR System of Care (shown below). 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.
Early initiation of BLS has been shown to increase the probability of survival for a victim of cardiac arrest. To increase the odds of surviving a cardiac event, the rescuer should follow the steps in the Adult Chain of Survival.
