The governor told reporters that an army doctor, the only physician in Thailand who is also trained as a Navy SEAL diver, was at the scene and was prepared to enter the cave to treat any survivors before they are moved.
Experts have prepared special foods that officials say could help the boys and the coach recover after going hungry for many days.
“The food is similar to the food given to astronauts,” Mr. Narongsak said. “They can eat just a bit — but they will get nutrition, and it is high in protein.”
Rescuers also have been working on a plan to bring survivors, who at best would be very weak, out through the flooded cave.
“They have to be in stable condition to be ready to come out,” he said. “The doctor, who can dive, will go in to make an assessment and solve the problem for us.”
