Carbon dioxide narcosis : Influence of short-term high concentration carbon dioxide inhalation on EEG and cortical evoked responses in the rat
The effects of 1 min exposure to 80% CO2 inhalation was studied in rats under light general anaesthesia with N2O. It was found that 80% CO2 gave a rapid slowing of the EEG as well as a rapid decrease of the amplitude of cortical somatosensory evoked potentials. Only minor influences upon the blood pressure and heart rate were seen. The changes were found to be transient and most of the EEG effects
