Improved predictive models for acute kidney injury with IDEA: Intraoperative Data Embedded Analytics
Fig 4
Association between risk of postoperative acute kidney injury and magnitude and duration of intraoperative physiological variations.
The risk for the development of postoperative acute kidney injury (AKI) within the first seven days after surgery, as predicted by the postoperative stacked model, was aggregated across the entire cohort. The color represents the risk of developing postoperative AKI, where red is high-risk, and green is low-risk. The y-axis is time (minutes) and the x-axes are (A) diastolic blood pressure (mmHg), (B) systolic blood pressure (mmHg), (C) Mean arterial blood pressure (mmHg), and (D) Heart rate (beats/minute).
