Divers Alert Network (DAN) includes a question for those who report suffering freediver blackout regarding their use of a snorkel. Hopefully, we will have a scientific answer to this question as data develops over the next few years. Until then, I'm keeping my snorkel in.
With snorkle out; what is the mechanism of H2O aspiration?

& How does retained snorkel prevent H2O aspiration?
