Haemodynamic monitoring is a central pillar of intensive care. Haemodynamic variables are commonly checked at the bedside, such as heart rate, blood pressure and capillary refill time.  Among the haemodynamic monitoring variables, lactate can be useful in the intensive care setting.  Increased lactate is traditionally associated with tissue hypoxia, confirmed by clinical studies, which have shown a relationship between increased lactate and reduced tissue oxygen supply (DO2). However, mechanisms other than tissue hypoxia can also trigger an increase in lactate. Lactate can be used as a prognostic marker, since a reduction in lactate in patients with shock has been associated with less organ dysfunction, shorter duration of mechanical ventilation and ICU stay, and reduced mortality. However, the use of lactate clarification should be used with caution as it can cause harm to patients.
