    During acclimatization to moderate altitudes, a simple calculation from data of others shows that the rise in cerebral blood flow (CBF) is sufficient that oxygen delivery to brain (DaO 2) is constant as arterial oxygen content (CaO 2) falls. This balance occurs on average even though the hypocapnia caused by hypoxic hyperventilation causes cerebral vasoconstriction, conflicting with hypoxic cerebral vasodilation.Author: Christopher B. Wolff

    Cerebral blood flow velocity (CBFV) was recorded for three minutes prior to and during pure oxygen inhalation (2 L/min), respectively, using a transcranial color-coded duplex (TCCD) sonography at the middle cerebral artery (MCA).

    Jun 27, 2014 · The degree of change in CBF at high altitude is influenced by many variables, including arterial oxygen and carbon dioxide tensions, oxygen content, cerebral spinal fluid pH, and hematocrit, but can be collectively summarized in terms of the relative strengths of four key integrated reflexes: 1) hypoxic cerebral vasodilatation; 2) hypocapnic cerebral vasoconstriction; 3) hypoxic …Author: N AinsliePhilip, W SubudhiAndrew
