Question 6: Carbogen therapy reduces cerebral blood flow. Select one: a. True, b. False

Answer

The correct answer is False. Carbogen is a mixture of oxygen (typically 95%) and carbon dioxide (typically 5%). Carbon dioxide is a potent vasodilator in the cerebral vasculature. When inhaled, the increase in arterial CO2 levels causes the blood vessels in the brain to widen (vasodilation), which results in an increase, rather than a reduction, in cerebral blood flow. This effect is often utilized in medical settings to improve oxygen delivery to various tissues.
