A wide range of thresholds define intraoperative hypotension and can be used to guide intraoperative blood pressure management. Many clinicians use the systolic blood pressure (SBP) <80 mmHg, the mean arterial pressure (MAP) <60 mmHg and the SBP percent drop from baseline (ΔSBP) >20% as alarming limits that should not be exceeded. Whether these common thresholds are valid limits that can inform clinicians on a possible increased risk of post‐operative complications, particularly 30‐day mortality, is currently unclear.
