Our instructor even offered the opinion that soon, even rescue breathing will be done away with - only rapid chest compressions and AED if available.
Here's the skinny on doing away with mouth-to-mouth. In essence, the conclusion is that one is better off getting compressions than no help at all.
In April, 2008, the American Heart Association (AHA) took steps to simplify the process of helping victims of cardiac arrest by introducing "hands-only" CPR. Since only about 1/3 of people who suffer a cardiac arrest at home or at a public place actually receive help, bystanders could be afraid to initiate CPR for fear that they'll do something wrong or won't know what to do. Others may be reluctant to perform mouth-to-mouth breathing for fear of contracting an infection.
