Development and Validation of a Wearable Doppler Ultrasound Sensor for Field Medicine, Transport Monitoring, and Acute Patient Care
Abstract
There is a need for enhanced medical monitoring in the field, in transport, and in the hospital for Soldiers impacted by trauma and infection in the field. We have developed a portable, adherent, and disposable Doppler ultrasound patch ideally suited for assessment of serious medical issues especially in resource-limited environments. The technology being developed in this proposal works by non-invasively measuring blood flow through the carotid artery to detect early and evolving shock, which results from field trauma. This study intends to develop a new type of medical sensor to assess the effects blood loss. We will study healthy male and female volunteers (age 18-40) who are able to undergo simulated blood loss. The results of the study will have direct applicability to military operational medicine, combat casualty care, and military infectious disease medicine. We hypothesize that: (1) Carotid blood flow can be measured using a light-weight, adhesive Doppler patch worn over the carotid artery. (2) Data obtained from the Doppler patch will be more sensitive measures of impending and evolving shock as compared to standard vital signs. (3) Simulated fluid challenge will be detected in the Doppler patch and can provide a new means of assessing resuscitation in the field. There are several cross-cutting benefits of this technology to applications for damage control resuscitation, austere surgical stabilization, and prolonged field care. Other synergies of the Doppler sensor technology could also help with pilot monitoring during high G maneuvers, providing real-time monitoring in field surgeries, and providing useful medical parameter for triage in multiple casualty situations. At the conclusion of the project, we will have developed a new, lightweight, non-invasive, and wearable sensor that will enhance medical monitoring and decision-making in the field and in the hospital.
