Pathophysiology
Decreased cerebral blood flow. The ischemic cascade begins when cerebral blood flow decreases to less than 25 mL per 100g of blood per minute.
Aerobic respiration. At this point, neurons are unable to maintain aerobic respiration.
Anaerobic respiration. The mitochondria would need to switch to anaerobic respiration, which generates large amounts of lactic acid, causing a change in pH and rendering
Loss of function. The membrane pumps that maintain electrolyte balances fail and the cells cease to function.
