I had to look into the mouth breathing as well, since it seemed unlikely that breathing through your mouth would cause lower oxygen saturation than nose breathing. It was interesting in that the first page of articles on google reiterated nonsense about only air passing through the nose could be properly absorbed. There were absolutely no citations. It was essentially the same article written in slightly different ways. And this is how fake news happens.
