Abstract

Cerebral blood flow (CBF) decreases with hypocapnia4,6. However, measurements of CBF a few hours after the induction of hypocapnia suggest that there is some secondary recovery of CBF over time1,3,5. The time course associated with this is uncertain. This study used transcranial Doppler ultrasound to assess the dynamics of the middle cerebral artery (MCA) blood flow response to 20 min of hypocapnia (Pet CO2=15.0 Torr below eucapnic value).
