Noninvasive Detection and Localization of Occult Hemorrhage

TThe goal of this development effort is to produce a noninvasive or minimally invasive capability that enables Role 1 medical personnel (specifically, a combat medic with no surgical or pre-operative imaging expertise) to rapidly detect, localize, and characterize the rate of life-threatening, occult, or non-compressible torso hemorrhage (NCTH) that cannot be precisely identified through routine clinical assessments available in the field. The proposed solution should integrate advanced sensing technologies with artificial intelligence to provide accurate, real-time detection, anatomic localization, and quantitative or semi-quantitative estimation of bleeding rate, distinguishing slow or self-limiting hemorrhage from rapidly expanding, exsanguinating hemorrhage, and should function in austere and contested environments. The capability should support serial or continuous monitoring such that changes in hemorrhage rate can be tracked to provide updates to the medic in near-real time. Solutions should provide intuitive, actionable visualization of both hemorrhage location and rate to support timely medical decision-making, triage, and evacuation prioritization when definitive surgical care is delayed or denied.
