All lay rescuers should, at a minimum, provide chest compressions for victims of cardiac arrest. In addition, if the trained lay rescuer is able to perform rescue breaths, he or she should add rescue breaths in a ratio of 30 compressions to 2 breaths.
When talking to people about first aid and CPR in particular, I find a lot of confusion centred around the ratio of compressions to rescue breaths. That is, how many times should you press down on the chest and how many times should you give mouth to mouth breaths.This is really not too surprising, as it has been subject to change over the years. I started to learn first aid in the winter of 1971/72, at the tender age of 8.f, however, you have help, then you should give 5 compressions to 1 breath. In my 1979 book, I am told that the correct ratio is 5 to 1, with or without help, but by the second half of the eighties we are back to 15 to 2 on our own or 5 to 1 with help.
