Design of an e-Health Respiration and Body Posture Monitoring System and Its Application for Rib Cage and Abdomen Synchrony Analysis
Bibliographic record
Abstract
Automated methods of real-time and un-obstructive patient's respiration and position monitoring have been subjects of interests in e-health applications. The present study implements a low-cost and convenient monitoring system for patients with breathing problems or sleep disorders. We have also captured the Rib Cage (RC) and Abdomen (AB) movements using accelerometer sensors. In addition to measurement of phase shift between the chest wall compartments, the impacts of different body positions on AB and RC motions have been investigated. The performance of the presented system is evaluated and the average Mean Square Error (MSE) of 0.14 is achieved for three breath timing variables. Moreover, the overall errors of phase angles for paradoxical and synchronous breath patterns are 0.25°±0.06 and 0.26°±6E-03, respectively. The system properly indicates a significant increase in the degree of ribcage and abdomen asynchrony in the paradoxical breathing compared to normal pattern.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
