Clothes must be removed to apply the pads to a bare chest. You may have to cut clothes and undergarments off. You may have to shave a hairy chest. If no razor is available you can apply an old set of pads then rip them off or use tape to rip the hair off.
Remove the pads from the package.
Apply the pads as shown on the packaging. One pad goes on the upper right chest. The other pad goes on the left side of the chest under the left armpit.
Do not apply pads directly on a implanted pacemaker. It looks like a lump under the skin on the left upper chest.
Check for a pulse. Start chest compressions if no pulse. Do chest compressions at 100 compressions per minute for 2 minutes. Press hard and go fast!
After 2 minutes has passed the AED will prompt you to analyze the heart again. Stop compressions. Wait for the AED to analyze the heart again. It may direct you to deliver another shock.
Don't stop chest compressions until a medical team arrives to take over or until the person regains a pulse and starts breathing again. Leave the pads on. The person will go to the hospital in the ambulance.
