Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection [1, 2]. Sepsis and septic shock are major healthcare problems, affecting millions of people around the world each year, and killing as many as one in four [3].

Early resuscitation is a key factor for the stabilization of sepsis-induced tissue hypoperfusion and is crucial to limit adverse outcome and death, especially in patients with septic shock.

Serum lactate is widely used in sepsis and, despite it is not a direct measure of tissue perfusion, it can serve as a surrogate. The Surviving Sepsis Campaign proposes to guide resuscitation by reassessment of blood lactate levels every 2–4 h until normalization according to randomized controlled trials [4]. However, the persistent increase of lactate may be related to other causes than tissue hypoperfusion, i.e., severe hypoxemia. Therefore, finding an alternative resuscitation targets becomes relevant in sepsis research.
