Potential effects of hyperventilation on the central nervous system include which of the following?
1) Increased O₂consumption
2) Increased cerebral vascular resistance (CVR)
3) Increased intracranial pressure (ICP)

Question

Quizplus · Accepted Answer

Hyperventilation can cause a decrease in carbon dioxide levels in the blood, leading to vasoconstriction and increased cerebral vascular resistance, which can result in increased intracranial pressure. However, hyperventilation also causes an increase in oxygen consumption by the brain, which is the opposite of choice 1. Therefore, the correct answer is 2 and 3 only.
