One hundred and seventy‐one estimations of arterial pH and pCO 2 were correlated with quantitative electroencephalographic findings during open heart surgery in thirty‐four patients. Electroencephalograms could not be related to such fortuitous changes in the pH and pCO 2 during open heart surgery as might occur in normal activity of the brain or body. It is not possible to measure the pH of cortex in human studies, and data based on blood flowing from a peripheral artery may not accurately reflect changes in the brain. Also, there may be some mechanisms by which the brain is protected from wideswings of acid‐base imbalance.
