Abstract
Modern health care system requires certain critically ill patients to monitor their blood pressure continuously through non-invasive techniques. The pulse transit time (PTT) and other parameter such as RS2 have been used previously for continuous BP monitoring. In this study, a system is designed using trial axis accelerometer as a sensor to collect seismocardiogram (SCG) data. The SCG waveforms have been used to find a relationship between Systolic Blood Pressure (SBP) and different axis of Seismocardiogram on 10 subjects aged 24+ years. The results reflect that the SBP is correlated with the starting point of the SCG wave in the x-axis to the mid-point of the z-axis. Their mean correlation and equations have been found which can state the systolic blood pressure of the subjects. The relative errors between the calculated SBP and the SBP measured from clinical equipment are up to 123 mmHg in normal range and 456 mmHg in high range. In summary, SCG can be used to determine the SBP as it has a moderate correlation.

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 it
