Dr. Andrew tried an entirely new method but he managed to save the life of the child. What was the method which was the last resort for him?

Dr. Andrew began a special method of respiration. He took two basins and plunged the child into the icy water and then into the steamy water. As a last resort, he rubbed the child’s body, crushing and releasing his chest. Suddenly, the child’s chest moved and it gave a cry. This is how he saved the baby.
