"The Duration of Brain Survival in Oxygen-Deprived Conditions"

The brain can sustain irreversible damage or die from oxygen deprivation within minutes, with permanent damage occurring as quickly as four minutes after blood flow stops. Factors such as the extent of oxygen loss, individual health, and pre-existing cardiovascular conditions can influence the exact timing of brain cell death. In cases of cardiac arrest, brain electrical activity ceases within 10 to 30 seconds, and rapid treatment is crucial to prevent severe damage or death. The article emphasizes that the rate of damage varies from person to person and is not meant as medical advice.
