How much o2 does the brain use?

Brain Oxygen Consumption and Regulation The normal human brain consumes 3.5 ml of O2 per 100 g of brain tissue per minute, a value which remains constant throughout periods of wakefulness and sleep. This relatively high rate of oxygen consumption is appreciable when compared to the metabolic rate of the entire body.
