Oxygen delivery and consumption in patients with hyperdynamic septic shock

Abstract

We analyzed the relationship of increases in oxygen delivery to changes in oxygen consumption in ten patients with hyperdynamic septic shock. Increases in oxygen delivery from 413 +/- 14 (SEM) to 535 +/- 19 ml/min X m2 (p less than .01) were associated with increases in oxygen consumption from 136 +/- 10 to 161 +/- 5 ml/min X m2 (p less than .05). Arterial lactate decreased from 4.6 +/- 1.6 to 2.1 +/- 0.3 mmol/L (p less than .05). These observations suggest that oxygen utilization is perfusion-limited in hyperdynamic septic shock.
