A Prospective Observational Comparison Between Arm and Wrist Blood Pressure During Scheduled Cesarean Delivery
Bibliographic record
Abstract
( Anesth Analg . 2015;121:767–775) Monitoring of both absolute values and clinically significant changes in patient blood pressure (BP) during cesarean delivery (CD) is important for patient welfare. A 20% increase or decrease in BP from baseline normally triggers treatment intervention. Common practice is to take the BP measurement from the upper arm. However, shivering or arm movement during delivery can lead to BP inaccuracies. Studies have shown leg measurements to be ineffective at detecting changes in BP in this patient population, and the forearm/wrist area has been suggested as an alternative as it has less muscle mass and is less prone to movement. In this single-center, prospective, observational study, authors compared upper arm measurements to wrist BP measurements in 49 nonobese pregnant women (older than 19 y) undergoing elective CD under spinal or combined spinal-epidural anesthesia. They hypothesized that change in wrist systolic BP (sBP) would trend with change measured at the same time in the upper arm, with an absolute difference between methods of <±10%.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
