Abstract
One hundred forty-five electroencephalograms and pH, pCO2, and oxygen pressure in arterial blood in 125 patients with chronic pulmonary diseases were examined. General characteristic electroencephalographic finding is diffuse slowing without any significant asymmetry or focus. Abnormal electroencephalograms increased with elevated pCO2 and lowered pH in arterial blood. The mean value of pCO2 in the group with abnormal recordings is significantly higher than that of the group with normal recordings, and the mean value of pH in the group with abnormal tracings is significantly lower than that of the group with normal tracings. There is a close correlation of electroencephalography with pCO2 and pH in arterial blood both in groups and in individuals. The electroencephalogram was normal in persons with arterial blood pCO2 below 42 mm Hg, while no normal tracing was seen in those with a pressure higher than 48 mm Hg. The inimate relationship of electroencephalography with pCO2 and pH in arterial blood may be helpful for diagnosis and for evaluation and treatment of pulmonary encephalopathy.
