What is asphyxiation?

1. A condition of excessive breathing

2. Not breathing, resulting from oxygen imbalance

3. A type of allergic reaction

4. A chronic lung condition

The correct answer is: Not breathing, resulting from oxygen imbalance

Asphyxiation occurs when there is a lack of oxygen and a buildup of carbon dioxide in the body, leading to a deprivation of oxygen necessary for bodily functions. This situation often arises due to an obstruction of the airway, which can prevent proper breathing. The oxygen imbalance leads to the body's inability to perform vital processes, resulting in potential loss of consciousness and can be life-threatening if not addressed promptly. By understanding asphyxiation in this manner, it becomes clear that the emphasis is on the absence of breathing or effective air exchange, rather than any of the other options which describe different physiological or medical conditions that do not specifically relate to the critical lack of oxygen experienced in asphyxiation.
