Abstract:
Arteriojugular oxygen difference (AJDO2) is used to manage the care of acute head-injured patients by monitoring the relationship between cerebral metabolism and blood flow. Blood samples from the jugular bulb and a peripheral artery are monitored either continuously or episodically to calculate AJDO2 and cerebral oxygen utilization. An understanding of cerebral oxygen transport physiology is essential to measuring AJDO2. A case study highlights the use of AJDO2 monitoring.
