Key result
Inhaling 6% CO2 for 10 minutes produces only slight transitory EEG changes without clinical symptoms.
Why the study?
Does 6% CO2 inhalation alter EEG patterns in normal young and older subjects?
Observational
Does 6% CO2 inhalation alter EEG patterns in normal young and older subjects?
Inhalation of 6% CO2 for 10 minutes produces only slight transitory EEG changes and no clinical symptoms in normal young and older subjects.
Supports tolerability of brief 6% CO2 inhalation in healthy adults; leaves open effects in clinical populations.
As a sequence to the evaluation of the electroencephalogram (EEG) in normal aging men exposed to mild hypoxia,17a similar study was instituted using carbon dioxide in low concentration as a stress agent toward a better understanding of the normal aging process,16,21and early cerebrovascular disease.2,3,13 We have reviewed the electroencephalographic (EEG) pattern and the relationship of alveolar CO2and pulmonary ventilation to the EEG in normal young and older subjects, whose mean ages were 24.4 years and 60.7 years respectively, during breathing a CO2gas mixture. Particular attention was given to the older subjects whose aging process had been uncomplicated by detectable disease. Analysis of the EEG pattern was made within and just without the normal range, since it became apparent early in the study that 6% CO2inhalation for 10 minutes produced only slight transitory changes and no apparent clinical symptoms.

RALPH ROSSEN (1963) conducted an observational in Healthy subjects. 6% CO2 inhalation was evaluated on EEG pattern and relationship of alveolar CO2 and pulmonary ventilation to the EEG. Inhalation of 6% CO2 for 10 minutes produced only slight transitory EEG changes and no apparent clinical symptoms in normal young and older subjects.
