In the book "Catching Fire," Peeta is injured during the Quarter Quell Games. He is shot in the leg by a Careers tribute, causing severe blood loss. However, he doesn't receive CPR, and the scene doesn't focus on any medical procedures to revive him.
In the movie "Catching Fire," the scene is changed slightly. While Peeta is still shot in the leg, the injury is less severe. He doesn't experience significant blood loss and is treated by medical personnel on the scene.
Therefore, there's no instance where Peeta requires CPR in either the book or movie. The focus is on the severity of the leg injury and the subsequent treatment.
