Arterial and venous pressures are dependent on the patient's access and the QBS. Ideally, the arterial pressure should be no more than - 250, and the venous no greater than 300. But, as mentioned above, it depends much on the patient's access.
brain extracts more oxygen from the blood, and there is a decrease in oxygen content or saturation of the venous effluent from the brain (widened AjvDO 2). Jugular venous oxygen saturation is normally approx-imately 55%â75% (1), which is lower than systemic mixed venous oxygen saturation. If the hemoglobin concentration is stable, the arte-
