Augmenting ProPatch, a BATDOK-Integrated Compact Patient Monitor, with Compensatory Reserve Measure using Physiological Simulator

A future war is anticipated to be with a peer or near-peer adversary that may pose a significant threat to transport vehicles, thus casualty evacuations may be delayed or unavailable. This requires that the forward warfighter be equipped with portable medical monitoring equipment to improve triage, effective care, and casualty survival rate at the point of injury. Current gold standard patient monitoring equipment, such as a Zoll Propaq, Stryker Lifepak15, or Philips Tempus Pro, is too large and bulky to be carried by a forward medic. Even if this equipment was available, traditional hemodynamic measures like heartrate and blood pressure are insufficient in predicting hemorrhagic shock, the leading cause of death on the battlefield. Therefore, there is an unmet operational need to drastically miniaturize and augment gold standard equipment to enhance the effectiveness of the forward medic in austere environments. ProPatch seeks to address these needs by providing comprehensive physiological monitoring in a compact package, with the inclusion of next-generation vital signs for predicting hemorrhagic shock. The work proposed involves the development of Compensatory Reserve Measure (CRM), a next-generation vital sign that detectsáhypovolemia and impending hemorrhagic shock, for real-time deployment with ProPatch. CRM will be developed through the use of a digital simulator to generate realisticáphysiological waveforms that are representative of hypovolemia. Data will be collected with ProPatch using the simulator and a CRM model will be trained, validated, and tested. The developed CRM model will be deployed to the ProPatch Connect iOS App and to the ProPatch-BATDOK plugin. The completed system will be demonstrated to the identified DAF end-user.
