CPR or Cardiopulmonary resuscitation has been around since the second world war and has undergone numerous changes. Researchers continue to monitor the effectiveness of it and will make changes to areas that are not as efficient as others. American heart association and Heart and Stroke Canada lay the ground work for all changes and monitoring of survivability. It is not one doctor that makes a decision, it is a collection of doctors that head up the board that review and change as needed.
The only way of finding the limits of the possible is by going beyond them into the impossible.Arthur C. Clarke
All nurses and the general public train under the BCLS guidelines (basic cardiac life support) this takes into consideration the chain of survival , chest compressions and artificial respiration. Brain death occurs after 4 minutes of not breathing and no circulation. So by being the first responder it is critical to start cardiopulmonary resuscitation as soon as possible the longer the delay the harder to save the life. It may disconcerting to push on someone’s chest but think of the alternative, death.
I remember my first time. It was the weirdest feeling pushing on someone's chest. It seemed to go against all the training I went through; to do no harm. Obviously, when you are doing chest compressions it is because that is the last resort. When the people do survive the arrest they don't ask "why did push on my chest? That hurt!" CPR saves lifes.
Take calculated risks. That is quite different from being rash.
George S. Patton
Specially trained nurses in high risk areas of the hospital and all doctors take ACLS (advanced cardiac life support) training. This reinforces the BCLS training but adds on the rhythm analysis and drug component of saving a life. Recently the studies show that survivability occurs with BCLS not ACLS so it is the early start of and continuous chest compressions that makes the difference, not the fancy equipment or expensive drugs. Good quality hard and fast chest compressions save lives.
There are numerous training courses in your area that is not hard to find. I advise learning this valuable life saving tool. If a preson has been not breathing and no circulation for 4 mins or longer commonly referred to as VSA ( vital signs absent) arrives in my emergency the chances of bringing them back is slim to none. So remember the first responder has the unique chance to make a difference in someone’s life, by saving it!
Below is an example of the old algorithm that the American heart association and heart and stroke Canada use to train people.
