proper CPR is performed with alternating chest compressions with mouth-to-mouth breathing. This
process helps push oxygen into the lungs so that it can go to the brain and keep a person alive.
The most common CPR technique that is taught at first aid courses around Australia involves
thirty chest compressions and two deep breaths. After that, the rescuer returns to performing
chest compressions, then back to giving two more deep breaths. This pattern is maintained until
proper help arrives. It is a simple technique, but knowing how to do it properly is key; the only
good way to learn is by being taught at a first aid class.
