When beginning mouth to mouth respiration you should start with?

When beginning mouth to mouth respiration, you should start by assessing the victim with the ABC's (Airway-tilting the victim's head back to ensure open airway, Breathing-make sure that the victim's chest is going up and down that means the victim is breathing, Circulation- check the victim's pulse) If the victim is not breathing, skip checking the pulse and start CPR. First, give the victim two breaths. Breath in and out when giving the breaths just as you would when you breath regularly. Then, start giving the victim CPR pumps or whatever you call it when you pump the victim's chest. This is all I can tell you- I am a lifeguard and if you want to know all about CPR you need to be properly taught. :)
