chosen: To perform CPR on someone, start by putting your arms straight out in front of you and then placing your hands together in the shape of a cup. Place the hands about breastbone high on the person's chest. Then, compress the breastbone 1/3 of the depth of the chest. Continue compressing the breastbone at a rate of 100 to 120 compressions per minute until help arrives or the person begins to recover. To breathe, tilt the head back slightly and place the hands on the lower third of the person's neck. Make sure that your fingers overlap slightly as you deliver two puffs of breath into the person's mouth approximately 2 seconds each. Repeat until help arrives or the person begins to recover.
