Imagine you're at the mall and a man or woman collapses.

You can increase or even triple that person's chance of survival if you start CPR
Mayo Clinic doctors say a modified form of CPR will save more lives. It's easier to learn, easier to do ... And you don't have to blow in someone's mouth.

"Mr. Jones are you o.k? Are you o.k?"

Dr. Tyler Vadeboncoeur and his colleague Dr. Bentley Bobrow are using a mannequin to demonstrate an updated version of CPR called continuous chest compression CPR.

"The goal is to generate blood flow to the heart and brain."

When a person collapses, there's still enough oxygen in their blood to keep them alive for about 10 minutes. But only if that blood gets to the brain. Chest compressions build up the pressure that keeps blood flowing to the heart and brain. If you stop pumping the chest for any reason, the patient's blood flow stops. Continuous chest compression CPR, keeps the oxygen-rich blood flowing.

"The key is to circulate that oxygen."

"The way to do that is to continuously push hard and fast on the chest."

Without stopping to breathe for the patient. This makes the process easier to learn, remember and do. No need to count compressions or breaths. No need for mouth to mouth breathing.

So if you're out in public or at the office and someone collapses call 911.

Then rub their chest hard to see if they wake up. Then start pumping.
"Put one hand on the sternum, the second hand on top of it. You need to push hard about two inches down. You want to get a rate of 100 times a minute. And you don't want to stop until emergency medical services or paramedics arrive. No need to worry about hurting the person.

"This person's dead. If you do nothing, they're dead. All you can do is help them."

The Mayo Clinic doctors say continuous chest compression is ideal for adults.

It is not for children under eight ... Or the rare case of respiratory failure or drowning.
For these people, standard CPR remains the best option.
