Cerebrovascular Response to Hypocapnia in Normal and Brain-Injured Dogs
Chapter
Abstract
It is well known that hyperventilation decreases cerebral blood flow (CBF) by increasing cerebrovascular resistance. Positive pressure hyperventilation produces not only hypocapnia but also a rise in mean intrathoracic pressure, a decrease in venous return, with subsequent increase in central venous pressure (GVP), and a decrease in cardiac output (1).
