Today knowing how to help someone is important. Learning CPR Denver is a very helpful skill when you are faced with an emergency. When someone has a heart attack the faster they get assistance the better chance they have to survive. When a person is able to perform this type of assistance right away, there is less chance of complications such as lack of oxygen to the brain and so on. The heart pumps blood throughout the body and when there is a problem with the heart there is a risk to the brain and the rest of the body for lack of oxygen and blood. When the brain is starved for oxygen there can be many different medical problems that will arise.
