Abstract
In the unanesthetized rabbit, autoregulation of cerebral blood flow was evaluated by continuous recording of local cerebral blood flow during progressive hypotension induced by exsanguination. Under hypercapnia induced by CO2, 8% in air, autoregulation was not suppressed but an increase of the threshold under which autoregulation disappears was noted.
