It is possible that you will have a small amount of water in your mouthpiece, so to avoid inhaling water into our throat, we use airway control. The following are proper airway control points to remember if you have water in your mouthpiece:
- Exhale sharply through the mouthpiece, or use the purge button on the second stage to remove water.
- After clearing your regulator, inhale cautiously.
- Use your tongue as a splash guard by putting the tongue tip on the roof of your mouth when taking initial breaths. You should also do this when using the regulator’s purge button.
- After inhaling slowly, exhale sharply to expel any water left.
If you cough from inhaling a little water, don’t worry. Relax and cough into the mouthpiece while holding it in your mouth. This may seem challenging right now, but with experience, it will soon become second nature.
Even if you have to be sick underwater, you can hold the mouthpiece firmly in place and vomit. It's obviously not a nice feeling being sick anywhere, but it can be done underwater!
