CPR the external heart pumps oxygenated blood to the core ( Heart and Brain) keeping the individual perfused. It’s insane that many people still do not know how to perform this very simple procedure. I also found it crazy that some people do not understand the benefits of owning an AED. Being able to restore a normal heart rhythm by connecting an AED to someone experiencing a sudden cardiac arrest is amazing. An AED is not an expensive device. However, not being able to provide your loved one with the opportunity to live is a huge and costly loss.
