A new device for measuring conjunctival oxygen tension (PcjO2) was used for intraoperative monitoring during carotid endarterectomy. The PcjO2 measures local tissue oxygenation and, thus, reflects the oxygen delivery to the areas supplied by the internal carotid artery. PcjO2 was found to be sensitive to manipulation, clamping, and obstruction of the carotid artery; it provided a useful monitoring system for assessment of the cerebral circulation during carotid surgery.
一种用于测量结膜氧张力（PcjO2）的新设备被用于颈动脉内膜切除术的术中监测。PcjO2可测量局部组织氧合情况，因此反映了颈内动脉供血区域的氧输送情况。研究发现，PcjO2对颈动脉的操作、夹闭和阻塞敏感；它为评估颈动脉手术期间的脑循环提供了一个有用的监测系统。
