Summary

This study tested a computer tool that forecasts a mother's blood pressure 1 to 3 minutes ahead during a planned C-section under spinal anesthesia. 20 pregnant women participated, and doctors used the forecasts alongside their usual care to manage blood pressure. The goal was to see how accurate the forecasts were, not to change treatment decisions.

Inclusion Criteria: 1. Adult pregnant individuals (≥18 years old) presenting for elective or scheduled cesarean delivery. 2. ASA physical status 2 or 3 (obstetric patients without severe comorbidities). 3. Singleton pregnancy at term (≥37 weeks gestation). 4.

No known fetal anomalies or intrauterine demise. Exclusion Criteria: 1. Pre-existing or gestational hypertensive disorders (e.g., chronic hypertension, preeclampsia, eclampsia) or use of cardiovascular medications that can affect blood pressure or heart rate (e.g. propranolol for migraine) 2. Known major cardiovascular disease or arrhythmias requiring treatment (e.g., heart failure, significant valvular disease). 3. Planned use of non-phenylephrine vasopressors (e.g., ephedrine, norepinephrine) for routine BP management. 4. Allergy or contraindication to bupivacaine or phenylephrine. 5.
