Shock results from tissue hypoperfusion and microcirculatory dysfunction, and should thus not be restricted to hypotension. Although frequent, hypotension is not mandatory for the diagnosis of shock. In the absence of hypotension, increased lactate levels may indicate tissue hypoper-fusion and can be used to diagnose shock (at least at its initiation)....
