Why the study?
Recent concerns were raised that predictive abilities of the commercial Hypotension Prediction Index algorithm may have been overstated due to potential selection bias.
Does the Hypotension Prediction Index (HPI) algorithm improve the prediction of hypotension compared to a simple MAP alarm threshold?

HPI performance likely overstated by MAP selection bias; leaves open true incremental value pending unbiased validation.
Does the Hypotension Prediction Index (HPI) algorithm improve the prediction of hypotension compared to a simple MAP alarm threshold?
The Hypotension Prediction Index may have overstated predictive abilities due to selection bias and requires re-validation before clinical use.
