When they forcefully breathe, they take in WAY more air in such a short period of time than they would have if they were under water. This is benign. I don't know why you're so fixated on the matter. It's a trade off that's worked for these animals forever.Because they don't have gills the have to forcefully breath and they sleep with half of their brains and although oxygen in the water is less than in the air it's more than enough for dolphins since bigger animals like the white shark have gills
