Quizplus · Accepted Answer

Systemic vascular resistance results in intravascular pooling in the venous system.Some portions of tissue are overperfused,and some are underperfused.Improvement in systemic vascular resistance is an indication of improvement in septic shock.In septic shock,the heart rate and stroke volume increase,and cardiac output is higher than normal.In septic shock,SvO₂ levels may already be higher than normal.An increase in serum lactate levels may increase levels of acidosis and tissue hypoxia.
