Hand on heart - Hands-only (Compression-only) CPR of American Heart Association vs. Advisory Statement of European Resuscitation Council for Basic Life Support (BLS)

The American Heart Association changed the Guidelines for Adult Basic Life Support on 31(st) March 2008 online: Lay rescuers should perform Compression only CPR omitting mouth-to-mouth-ventilation. The ERC didn't judge it necessary to change European Guidelines that are based on the same common "Consensus of Science" (Dallas 2005), since ERC recommended even 2005 for lay rescuers to perform only chest Compressions if he or she is not able or willing to perform mouth-to-mouth-ventilation. The recent change of AHA Guidelines and also the ongoing ERC recommendation (ALS guidelines 2005) aims on bringing as many lay rescuers as possible to action and on achieving a better outcome for victims of a sudden circulatory arrest. The remaining question is: Are there good arguments for "Compression only CPR"?
