People over 50 are the most likely to need CPR for cardiac arrest. And they probably won't buy you dinner first. Are you ready for your first time doing CPR? If someone has a cardiac arrest you should give CPR as quickly as possible. Even if it's your first time doing CPR, it's better than nothing. Remember to call 000 then begin compressions. You should aim for 2 compressions a second and compress their chest 1/3 or 5cm while giving CPR.
