Conclusions: Our findings raise concerns about high levels of ScvO2 in patients with septic shock. This may reflect the severity of the shock with an impaired oxygen use. SpletPatients with septic shock were treated with either dopamine or norepinephrine to correct hypotension. Measurements and main results: SvO2 increased (62.6 +/- 6.7% vs. 69.5 +/- 6.0%, p less than .001).

SpletSeptic shock is the typical form of distributive shock, characteristically associated with a hyperkinetic (high cardiac output) state and normal or high mixed venous oxygen saturation (SVO2). 1 Rivers et al2 introduced the concept of early goal-directed therapy in septic shock, made on the basis of measurements of central venous SpletShock. Shock is a state of organ hypoperfusion with resultant cellular dysfunction and death. Mechanisms may involve decreased circulating volume, decreased cardiac output, and vasodilation, sometimes with shunting of blood to bypass capillary exchange beds. Symptoms include altered mental status, tachycardia, hypotension, and oliguria. SpletMAP level of 65 mmHg and SvO2 of 70% had the highest areas under receiver characteristics curves.
