Mouth breathers and portable oxygen tanks are a common site.
Some tanks may not be needed, if people would just breath right.
Close the mouth and breath through the nose.
Watch your pulse oximeter reading, it above 90 rose.
Breathing room air by mouth, will give you low oxygen blood gas levels.

Interesting post. I know some people have problems with sinuses, and have a lot of difficulty breathing. It is so scary to not breathe right.

That would be me. Chronic sinusitis. Only way to “cure” it is through surgery which may or may not work. I breathe through my mouth most of the time. Doesn’t help that I have asthma as well. >_<
