I think the symbolic thing about the whole cpr thing is Sakura actually has a thing for naruto. It's been foreshadowed ever since Naruto began. NaruSaku disagree or whatever I think is definitely going to happen. The only person that could possibly get in the way is Hinata. But if you were writing a story with a person at near death in it. A thing to do is put a lover by their side. Whether that character dies or survives. They both care deeply for one another. SURE IT WAS ONLY CPR. BUT for sakura to do it.... Also sakura wasn't disgusted she was determined to bring him back to life and also trying to squeeze his heart to pump blood was the reason for not looking at him in the face.... idiots...
