Pinch the person's nostrils shut with your thumb and finger.
fingers of your other hand under the bony part of the lower jaw near the chin. Tilt the chin upward to keep the airway open. Do not tilt the head if you think there is a neck injury.
Take a normal breath
(not a deep one), and place your mouth over the person's mouth, making a tight
seal. For a baby, place your mouth over the baby's mouth and nose. Blow into
the person's mouth for 1 second, and watch to see if the person's chest
rises. See a picture of rescue breathing for a baby.
If the chest does not rise, tilt the person's head again,
and give another breath.
Between rescue breaths, remove your mouth
from the person's mouth and take a normal breath. Let his or her chest fall,
and feel the air escape.
Using an automated external defibrillator (AED)
Automated external defibrillators (AEDs) are machines that are
programmed to safely deliver an electrical shock to a person who has collapsed
from a heart problem. Each AED has instructions for that machine.
AEDs are in many public places. Before you use an AED, follow all the steps for CPR. To use an AED, place it next to the person who has collapsed and turn it on. The AED has a computer inside that will tell you what to do next.
