Jugular venous oxygen monitoring
see Brain tissue oxygen monitoring
Indications for Jugular Venous Oxygen Saturation or PbtO2 monitoring include the need for augmented hyperventilation (pCO2 = 20–25) to control ICP. Parameters related to the oxygen content of the blood in the jugular veins are global in nature and are insensitive to focal pathology. Requires retrograde placement of the catheter near the origin of the internal jugular vein at the base of the skull.
Parameters that can be measured:
