Potential effects of hyperventilation on the central nervous system include which of the following?
I.increased O₂consumption
II.increased cerebral vascular resistance (CVR) III.increased intracranial pressure (ICP)

Question

Quizplus · Accepted Answer

Hyperventilation leads to decreased carbon dioxide levels in the blood, which causes vasoconstriction of cerebral blood vessels, increasing cerebral vascular resistance (CVR). This vasoconstriction can also lead to a decrease in intracranial pressure (ICP), not an increase. Therefore, increased oxygen consumption is not directly a result of hyperventilation's effects on the central nervous system.
