Here there is the danger of pendulum breathing. On the other hand, the water pressure makes breathing more difficult.
Can you breathe through a long tube?
Shallow breaths won’t flush the tube of CO2, and you wind up pushing spent breath a bit backwards and a bit forwards. Your lungs get that burning feeling, you get dizzy and headachy, then you pass out from the reduced oxygen if you keep it up too long. With normal snorkels, it’s really hard to get to ‘too long.
