Background: Hypocarbia causes slowing of background cerebral electrical ... median (range) of blood gas measurements were: pH: 7.3 (7.18 - 7.43); partial pressure of carbon dioxide (pCO2): 6. ...
Kety and Schmidt 3 demonstrated a 75 per cent increase in cerebral blood flow (average) in response to inhalation of 5 per cent carbon dioxide. They recorded minimal rises (1 to 6 mm. of mercury ...
Mapping vascular processes such as cerebral blood flow and oxygenation provide quantitative insights into brain function in health and disease. Quantitative MRI methods are used in the lab to ...
