BE
Description
Base excess / deficit (BE) in blood measured in first 10 minutes after admission to hospital using an arterial blood gas (ABG) test. BE variable is used as a marker for determining the Hypoperfusion state.
Excluded BN Elements
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.
