Breathe Efficiently When Scuba Diving

Breathing underwater is a skill generally reserved for little fishies. When we land mammals attempt it during scuba diving, we must proceed correctly.

From Quick Guide: Scuba Diving
Difficulty: Easy
Instructions

Things You'll Need:

  1. Step 1

    Understand that oxygen converts to carbon dioxide only inside the lungs.

  2. Step 2

    Know that everything else ' the throat, mouth and nose ' is dead-air space.

  3. Step 3

    Realize that snorkels and scuba regulators increase the length of normal dead-air spaces.

  4. Step 4

    Breathe deeply while diving, in order to flush out dead air and bring fresh oxygen into the lungs.

  5. Step 5

    Inhale slowly (with your tongue at the roof of your mouth, like a splash guard) in case water has entered the snorkel or regulator.

  6. Step 6

    Never hold your breath; trapped air will expand as you ascend.

Tips & Warnings
  • If you begin to choke, hold the regulator with one hand and cough or spit into it as much as necessary; the regulator can handle it. Just don't panic.
  • Scuba diving is an inherently dangerous activity that can result in serious injury or death. We recommend that you seek proper training and equipment before attempting this activity.
