Content: The exact process, of course, also depends on your scuba tank’s valve type. The regulator also compensates for the decreased pressure in the tank as the air is used and as the diver changes depth, which changes the ambient water pressure. Second Stage Regulator
The second stage of a scuba regulator is the part that goes into your mouth. It contains a mechanism that further reduces the intermediate pressure in the hose coming from the first stage to the surrounding water pressure, making it comfortable and easy to breathe. As with the first stage, the second stage also contains a piston or diaphragm construction which starts and stops the airflow. 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.
