Short episodes confusion, dizziness, and shortness of breath can be associated with intermittent declines in cerebral blood flow velocity (CBFv). CBFv decline without orthostatic hypotension or decline in end tidal CO2 can be seen in orthostatic cerebral hypoperfusion syndrome (OCHOS) associate with abnormal cerebral vasoconstriction due to cerebral autoregulatory failure.
