Abstract

This study examined the relationship between cerebral blood flow (CBF) and end-tidal Pco 2 (Pet CO 2 ) in humans. We used transcranial Doppler ultrasound to determine middle cerebral artery peak blood velocity responses to 14 levels of Pet CO 2 in a range of 22 to 50 Torr with a constant end-tidal P...
