[Influence of moderate normoxic hypercapnia on the autoregulation of the cerebral circulation in the unanesthetized rabbit].
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 per cent in air, autoregulation was not suppressed but an increase of the threshold under which autoregulation disappears was noted.
