SjVO2 Monitoring in Head-Injured Patients

  • Claudia S. Robertson
Conference paper


Studies of head-injured patients have demonstrated that a reduced cerebral blood flow (CBF) is associated with a poor neurological outcome [1]. Jugular venous oxygen saturation (SjVO2) is theoretically a useful monitor for cerebral hypoxia and ischemia because it reflects the balance between oxygen delivery to the brain and oxygen consumption by the brain. Because both delivery and consumption parameters can be abnormal after a head injury, the relative balance between these two parameters is often more valuable information than the absolute level of either of the parameters alone. Any disturbance that increases cerebral oxygen consumption or decreases oxygen delivery may decrease SjVO2. The purpose of this study was to examine the incidence and causes of jugular venous desaturation detected with continuous monitoring of SjVO2.
