My exam is on thurs kindly help

each of the following ios a sign of hyperventilation except one. which one is the exception?
1 cerebral blood flow.
2 arterial oxygen.
3 cerebrovascular resistance.
4 arterila ph
5 arterial oyxygen tension.

ans is blood flow(1)
if the blood flow decreases then wont tht be a signal for increase ventilation n thus worsening the situation.
plz explain

5 arterial oyxygen tension.

incresed pco2 or hypoventilation increases cerebral blood flow and acts on central chemoreceptors by increased hydrogen conc.in the medulla which in turn stimulates respiration
so increased cerebral blood flow shd be the sign of hypoventilation and not hyperventilation
