What Is Asphyxia?

Asphyxia happens when your body doesn’t get enough oxygen to keep you from passing out. It can be a life-threatening situation.

When you breathe normally, first you take in oxygen. Your lungs send that oxygen into your blood, which carries it to your tissues. Then your cells use it to make energy. Any interruption to the process of breathing in oxygen or breathing out carbon dioxide can make you pass out or even lose your life.
