“We here show that arterial oxygenation is improved in healthy awake subjects during nasal breathing as compared with mouth breathing.”
It’s Friday, so a new Science 411 is now available. It’s the study behind the “nose breathing increases oxygenation” line you see everywhere.
It’s a must-read/listen if you’re a breathing nerd.
Here are the take-home messages:
Nasal breathing increased tissue oxygenation by ~10% compared to mouth breathing in 6 of 8 healthy people.
Adding nasal air to a ventilator increased arterial oxygenation by ~18% in 6 of 6 mechanically ventilated people.
Read or listen to the new 411 to get all the details of this fascinating study. Enjoy!
