Variation in Measurement and Reporting of Goal Directed Perfusion Parameters.

The Australian and New Zealand Collaborative Perfusion Registry (ANZCPR) tracks perfusion practices from the nine centers contributing to the collaborative dataset. It is unique in that data from the heart–lung machine, monitors, and the electronic perfusion records are able to be imported into the dataset. This allows many physiological parameters to be reported, including oxygen delivery. Figure 1 illustrates the variation in minimum oxygen delivery (DO2i) in the nine centers. Why is there this much variation between the different centers? The aim of this paper is to outline what can influence the measurement and reporting of perfusion parameters, specifically those related to goal-directed perfusion (GDP) and to highlight potential sources of error in our measurements.
