Arterial oxygen tension and high intracranial pressure.
Arterial oxygen and carbon dioxide tension was measured in spontaneously breathing rabbits whose intracranial pressure was raised by a freeze lesion, oil embolism, or hydrostatic pressure. Reports elsewhere had stated that high intracranial pressure led to hypoxaemia. In this series of experiments, arterial oxygen tension appeared to rise and carbon dioxide tension appeared to drop. Both changes were slight and not significant statistically. There was no evidence to suggest that arterial hypoxaemia is caused by high intracranial pressure.
