Asphyxia primarily refers to the interruption of oxygenation of the brain. This condition arises when there is an insufficient supply of oxygen to the tissues, particularly affecting the brain, which is highly sensitive to changes in oxygen levels. When the brain is deprived of oxygen, it can lead to loss of consciousness, neurological damage, and ultimately death if not corrected promptly.

The critical factor in asphyxia is the lack of oxygen rather than other issues like trauma or blood circulation, which can also lead to loss of consciousness but do not specifically pertain to asphyxia. Understanding asphyxia involves recognizing that the brain's demand for oxygen is not being met, which aligns with the outlined definition.
