Variable:Tissue_Perfusion
Description:

The degree of inadequate oxygen delivery and perfusion to the tissues

Distribution:Discrete
States:
  • Compensated
  • None
  • Uncompensated
    • Evidence:
    Hypoperfusion_States(Supporting Evidence)

    Severity of hypoperfusion may be categorised as compensated / uncompensated (Williams et al., 2013). The method for classifying the hypoperfusion states is described by Yet et al. (2014).

    Excluded BN Elements:
    Tissue_Perfusion ↛ Respiratory_Rate

    Respiratory rate and GCS are also suggested markers for the degree of Hypoperfusion. We did not included these in the ATC BN since their accuracy as a Hypoperfusion marker is poor compared to the included markers
