Question

It’s difficult for doctors to help a person with a hurt brain. enough blood, the brain can live only 3 to 5 minutes. Usually doctors can’t fix the hurt such a short time.

Dr Robert White thinks he knows a of help. He thinks doctors should make the hurt brain to live for 30 minutes without blood. This gives the doctor time to do something for the brain. Dr White experimented his on fifteen monkeys. he taught them to do different jobs. Then he operated on them. He made the monkeys’ blood go a machine. When the brains’ was 10℃,he stopped the blood to the brain. After 30 minutes, he turned the blood back on. He the blood again. After their operations, the monkeys were almost before. They were healthy and busy. Each one could still do the job the doctor them.

Dr White’s idea works well on monkeys. He thinks it will work on . He thinks it will help with heart problems. A person die when his heart stops; doctors can it again. The problem comes: when the brain is without blood for about 5 minutes, it . If doctors start the heart again after 5 minutes, the person has body but a dead brain. Maybe in the future, doctors will Dr White’s idea. When the person’s heart stops, the doctor will cool the brain. They will have 30 minutes to start the heart again. Maybe there will be no the brain.
