Abstract
By the Hydrogen clearance method, focal blood flow has been measured under spontaneous breathing in the Rabbit. Blood flow in the spinal cord at Th-8 segment ranged from 30.7ml/100g/min to 6.5ml/100g/min. The overall mean was 18.55ml/100g/min± 1.57 S. E. (n=19). There had been no correlation between the variations of mean arterial blood pressure and spinal cord blood flow. Arterial blood Oxygen pressure had been significantly correlated with spinal cord blood flow. Under controlled P-CO2 and P-O2 condition, this technique appeared to be well suited to the spinal cord blood flow measurement, yielding reproducible results.
