Detecting occult hemorrhage bleeding using a new protocol called the UFOH protocol: Ultrasound Focused Occult Hemorrhage
Bibliographic record
Abstract
Point-of-care abdominal ultrasound (US) has emerged as a powerful tool for clinicians and is becoming a routine bedside tool to rapidly diagnose, manage hemodynamics, monitor fluid status, and guide procedures in emergency and critical care. Extended focused assessment with sonography for trauma (eFAST), is commonly used to detect free intraperitoneal blood in the trauma setting and may also be an option in non-trauma patients. However, it has significant limitations for detecting gastrointestinal or retroperitoneal bleeding. To date, there is no US protocol described for the diagnosis of occult bleeding in the retroperitoneal space. We describe a new US protocol called “Ultrasound For Occult Hemorrhage” (UFOH) for a fast diagnosis of occult hemorrhage. The UFOH protocol is a novel ultrasound-guided approach designed to detect occult bleeding in various clinical settings, including emergency department, intensive care and perioperative environment. La ecografía abdominal como «point of care», en el punto de atención, ha surgido como una herramienta potente para los clínicos, habiéndose convertido en una herramienta rutinaria a pie de cama para diagnosticar, manejar la hemodinámica, supervisar el estado de los líquidos y guiar los procedimientos de urgencias y cuidados críticos. Se utiliza comúnmente Extended Focused Assessment with Sonography for Trauma para detectar sangre libre intra-peritoneal en el ámbito traumático, pudiendo ser también una opción en los pacientes no traumáticos. Sin embargo, tiene limitaciones significativas para la detección de la hemorragia gastrointestinal o retroperitoneal. Hasta la fecha, no existe ningún protocolo ecográfico des-crito para el diagnóstico de la hemorragia oculta en el espacio retroperitoneal. Describimos un nuevo protocolo ecográfico denominado Ultrasound For Occult Hemorrhage para el diagnóstico rápido de la hemorragia oculta. Dicho protocolo es un nuevo enfoque ecográfico diseñado para detectar el sangrado oculto en diversos ámbitos clínicos, incluyendo los servicios de urgencias, cuidados intensivos y el entorno perioperatorio.

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; both teacher heads agree on what is shown here.
