What term describes the condition of being deprived of oxygen, which can lead to unconsciousness or death?

The term that describes the condition of being deprived of oxygen, which can lead to unconsciousness or death, is asphyxiation. Asphyxiation occurs when there is insufficient oxygen due to various reasons, such as choking, drowning, or being in an environment with inadequate oxygen levels. This condition directly affects the body's ability to utilize oxygen, leading to critical impairment of bodily functions, and can quickly become life-threatening if not addressed.

Understanding asphyxiation is crucial because it highlights the importance of maintaining adequate airflow and appropriate environmental conditions to support life. For instance, a person who has experienced asphyxiation may lose consciousness rapidly if the oxygen deprivation is severe, necessitating immediate intervention to restore normal breathing and oxygen levels.
