Final answer:

The normal ranges for CBF are 50 to 70 ml/100g/min and for CMRO2 are around 3.5 ml O2/100g/min. The balance between these values is essential for brain health, with factors like cardiac output, blood pressure, and gas levels affecting them.

Step-by-step explanation:

The normal range of cerebral metabolic rate of oxygen (CMRO2) and cerebral blood flow (CBF) are crucial indicators of brain health. While the information provided does not directly state these values, we can infer that normal values of CBF are typically around 50 to 70 ml per 100 g of brain tissue per minute. The CMRO2, on the other hand, is on average about 3.5 ml O2 per 100 g of brain tissue per minute. These values are necessary to sustain proper brain function and ensure adequate oxygen supply to neuronal tissue.

It is important to ensure a proper balance between CMRO2 and CBF to avoid conditions like ischemia or hypoxia, which can result from insufficient blood flow or oxygen supply to the brain. Factors that can influence these values include the body's oxygen demand, carbon dioxide levels (pCO2), blood pressure, and cardiac output (CO). The normal CO ranges from 4.0-8.0 L/min, emphasizing the interconnectedness of overall cardiovascular health and brain function.
