As long as the class is certified by the CPR association they should be the same. This is due to the training that is required to make the class certified.
If you are CPR certified, you should have someone call 911 while you start CPR. If you are not CPR certified, find someone around you that is.
Go to the place (or institution; such as ARC or AHA) where you received your certifications and inquire; if your cards have not been expired for long, you may be able to take the refresher class instead of the full class.
If CPR is successful, it means that the victim has been revived. He must be breathing and pumping blood on their own. Anything else is not successful.
