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.
Now you've got a good feel for how fast those compressions need to go. CPR is performed in what we call, cycles. One cycle of CPR includes 30 compressions, just like you've already practices, followed by two rescue breaths. Each breath should last about one second. Watch for the chest to rise with each breath. The cycle is then repeated: 30 compressions and two breaths; 30 compressions and two breaths. It is important to change from compressions to breaths and back to compressions as quick as possible.
