A Randomized Effectiveness Trial of Early Hemodynamic Support in Patients Demonstrating a "Triple Low" of Mean-arterial Pressure, End-tidal Anesthetic Concentration, and Bispectral Index

The investigators propose to test the theory that smart alarms for the Triple Low State incorporated into a decision support system built into an electronic anesthesia record will prompt clinicians to intervene earlier in situations that would otherwise provoke little concern, and that the alert system will reduce 90-day mortality. Specifically, the investigators will test the hypothesis that providing Triple Low alerts reduces 90-day mortality.
