The modern emphasis is on compressions, hence the Vinnie hands only "staying alive" ad. For one person, not trained in CPR, and in an area where an emergency response can be expected swiftly this hands only technique can be effective. The unfortunate reality is that for an adult, whose heart has stopped, it is unlikely to restart without intervention such as from a defibrillator, and thus the person giving initial assistance is seeking to prolong the timescale that the medics have to be effective.

However, CPR is cardiac pulmonary resuscitation. In other words heart compressions and breathing assistance. So for those who know how to do it effectively, especially if assistance might be delayed, the more thorough technique is appropriate. The biggest problem for many lay people is the time lost between compressions, repositioning to give breaths and returning to compressions. Latest guidance concentrates on those compressions, by a higher ratio of 30:2 compression:breath, with those compressions also slightly faster than older techniques, hence "staying alive", rather than "nellie the elephant".
