wait really does hypoxia or rising CO2 levels make the sphincter open to attempt to breathe anally??
If you're a turtle or a sea cucumber maybe.
IIRC during covid they did experiment with liquid oxygen exchange through the intestinal wall for patients whose lungs were so wrecked normal ventilators weren't sufficient. So you could maybe engage in some anal breathing if you were to get a super-oxygenated fluid enema, but its not something the unassisted human body can do. Or tries to do, for that matter.
Wanna try?
heck no ☠️
no
Is...is the one ring a cloaca??

Cloacin me crazy
Do turtles have a cloaca?
Edit: just searched it, and they do.
Wait, breathing?!
Yep, butt breathing is real:
That's how the turtle do.
Seriously, some aquatic turtles can extend their time under water by using their cloaca like primitive gills. Look up cloacal respiration.
