What is a symptom of extreme hypoxia?

Extreme hypoxia, which is a critical deficiency of oxygen in the body, can lead to severe physiological responses. Among these, collapse is a significant symptom. When the body does not receive enough oxygen, it can result in a loss of consciousness or the inability to maintain bodily functions, leading to a collapse. This condition reflects a critical state where the body's vital systems are compromised due to inadequate oxygen supply. Understanding this can help in recognizing the severe effects of hypoxia and the urgency needed in such situations. Other symptoms of hypoxia may not necessarily indicate an extreme situation; for example, yawning or headaches may occur in milder forms of oxygen deficiency, while personality changes might also stem from other factors rather than an acute lack of oxygen. Thus, identifying collapse as a symptom underscores the seriousness of extreme hypoxia.
