Brain cells can begin to die after just four minutes without oxygen, underscoring the severity of oxygen deprivation. This makes understanding what is the primary cause of anoxia crucial, though it's not a single factor but a variety of medical emergencies that completely cut off the body's oxygen supply.

In a high-altitude setting, loss of consciousness from oxygen deprivation can occur in as little as 10 seconds following rapid decompression. Understanding **how fast does hypoxia happen** is critical because the speed and severity depend entirely on the underlying cause.
