Effects of Graded Hyperventilation on Cerebral Blood Flow Autoregulation in Experimental Subarachnoid Hemorrhage

An impaired CBF autoregulation can be restored by hyperventilation at a PaCO2 level of about 2.9 to 4.1 kPa (22 to 31 mm Hg). However, it is uncertain whether the restoring effect can take place at lesser degrees of hypocapnia. In the current study, CBF autoregulation was studied at four PaCO2 level...
