Abstract

Oxygen transport has much relation to the condition of our living tissue. Cerebral hypoxia and ischemia cause many disturbances, and especially in the case of human newborn, it is important for us to monitor the oxygenation state of hemoglobin in cerebrum. But we have no instrument to monitor it non-invasively, directly and simply. In this case we usually use the percutaneous oxygen electrode monitor or the pulseoximeter. As for the fomer, the response is slow and it is difficult to apply it to the patient of peripheral circulatory incompetence, and for the latter in case of hypotension.
