Sasuke's brain sure as kitten didn't need oxygen. We literally only see her giving him CPR once and nowhere else is it implied again.
Sasuke ?
It's not a realistic manga.
Come on !
Do you expect scientific explanations and details ?
This is not a HOUSE episode...
We got a man that just stole an eye and plug it into his head LOL
Don't expect scientific logic !
Just put yourself in the author's shoes. He wanted to put the emphasis on something else. That's all. It was bothersome for him to continue to draw Sakura's hand moving into Naruto's chest, so he just let her hand in without any move because it was enough for us to understand that she was continuing. And he didn't draw her continuing artificial respiration because it was bothersome to draw, and because he needed to focus on something else. He just can't waste his time to draw things that we already understood. He has little time to draw his manga. It's a weekly manga. It must be hard for him to focus on everything. Can't you just understand that?
