C.P.R. is not difficult to learn. Many organizations teach it.

VOICE TWO:

Most C.P.R. training now includes how to use an automated external defibrillator, or A.E.D. Such devices are increasingly found in public places. A recorded voice guides the user. Defibrillators use electric shocks to correct abnormal heartbeats that can lead to sudden death.

But a recent report compared the effectiveness of defibrillators with rescue efforts by someone skilled at C.P.R. Scientists at the Seattle Institute of Cardiac Research and the University of Washington prepared the report.

VOICE ONE:

The researchers wanted to see if defibrillators could save lives. They studied seven thousand heart patients. Each person taking part had someone available in the home to give C.P.R.

Defibrillators were placed in the homes of half of the patients. In case of emergency, families in the defibrillator group were told to use the device first, before calling for help or performing C.P.R. The other families were told to call emergency services, then use C.P.R. The results were reported after an average of three years. They showed that the defibrillators provided no more protection from death than a person skilled in C.P.R.

VOICE TWO:

Bacteria can enter the body through even the smallest cut in the skin. So medical experts advise people to treat all wounds. Clean the cut with soap and water. Then cover the wound while it heals.

If bleeding is severe, doctors at the Mayo Clinic health centers suggest several steps. First, if possible, have the person lie down and raise the victim's legs. Remove dirt from the wound and press on it with a clean cloth or piece of clothing. If you cannot find anything clean, use your hand.

Keep putting pressure on the wound until the bleeding stops or medical help arrives. Do not remove the cloth if the blood comes through it. Instead, put another cloth on top and continue pressure. If the bleeding does not stop with direct pressure, put pressure on the artery that carries blood to the wound.
