    Hypoperfusion_Markers ↮ Base_Excess

    Relations exist between some markers of hypoperfusion. For example, pH is not independent of lactate levels when state of the hypoperfusion is known. However, these interdependencies were not considered for the modelling of this measurement idiom because there is no need to predict unmeasured values.
