4.0 Summary: Three Core Concepts to Remember
For any student of health and safety, mastering the vocabulary of asphyxiation comes down to these three foundational ideas.
- Choking is About Oxygen. The ultimate danger in all these scenarios—whether from food, water, or gas—is the body’s lack of oxygen, with cyanosis being the most urgent visible sign.
- Water-Related Dangers Can Be Delayed. Incidents involving water are not always over when the person is out of the water; “dry” and “secondary” drowning are serious delayed reactions that require immediate medical attention if symptoms appear.
- The Cause Is Not Always Obvious. Asphyxiation isn’t just about something stuck in the throat; it can be caused by external pressure (mechanical), invisible gases (chemical), or the body’s own reaction to water.
