Abstract
Summary
Experiments on unanesthetized rats show that rapid lowering of the barometric pressure to 130 mm Hg in 100% oxygen is not accompanied by any changes in the EEG although cortical potentials are abolished at this level in air. Further reduction in the barometric pressure leads in the presence of 100% oxygen to anoxic changes similar to those observed in the low pressure chamber in air at lesser altitudes.
