Content: The mouthpiece, exhaust valve, and an emergency purge valve (or button) are all part of the second stage of the scuba regulator. The exhaust valve lets the air escape into the water when you exhale. It is a one-way valve and does not allow water to enter from the outside. When the purge button (usually the front cover of the second stage in modern models) is pushed, it forces air to flow continuously into the second stage chamber forcing any water out of the mouthpiece through the exhaust valve. With this mechanism, divers are actually able to vomit while holding the second stage in their mouths instead of pulling it out and risking accidental water inhalation. It’s not pleasant to think about, but what is nice to consider is that this wonderful piece of technology makes it possible to survive underwater—even in the least optimum conditions—until you can safely return to the surface.
