How does hypoxia kill you?

Hypoxia, a condition where the body or a region of the body is deprived of adequate oxygen supply, can lead to cell and tissue damage, ultimately resulting in organ failure. Without sufficient oxygen, cells cannot perform essential metabolic functions, leading to the accumulation of toxic byproducts and the shutdown of critical systems. Prolonged hypoxia can cause irreversible damage to vital organs such as the brain and heart, leading to loss of consciousness, cardiac arrest, and death if not corrected promptly.
