In the high-stakes environment of combat, rapid medical intervention during the first 60 minutes, known as the “golden hour,” is critical to saving lives. However, the complexities of modern warfare often make it challenging to transport critically injured soldiers to surgical facilities within this time frame. Recognizing this gap, DARPA has launched the GOLDen hour extended EVACuation (GOLDEVAC) program, which aims to provide advanced medical care from the point of injury through the entire evacuation process.
Bridging the Gap in Combat Medical Care
The GOLDEVAC program envisions a revolutionary approach to managing severe combat injuries on the battlefield. Unlike current systems that require expert teams and cumbersome equipment, GOLDEVAC focuses on empowering field medics with automated resuscitation tools. These tools will enable medics to stabilize and manage complex polytrauma patients for up to two days.
Specifically, GOLDEVAC seeks to determine whether it is possible to resuscitate and oxygenate a patient, for up to two days, via a single tube inserted into a patient’s blood vessel, without the risk of blood clots or bleeding. Central to this innovation is the development of a single intravascular interface—a compact device inserted into a blood vessel to provide comprehensive casualty support. This interface enables:
- Oxygenation and ventilatory support.
- Medication infusion and fluid/blood resuscitation.
- Biofluid sampling and real-time monitoring.
- Closed-loop, automated trauma management for up to 48 hours.
This interface not only reduces the risk of blood clots and bleeding but also minimizes the equipment footprint, making it suitable for battlefield conditions. With a small insertion site of less than 15 French (5 mm), the interface can be safely and reliably used by field medics, even in austere and contested environments. Additionally, it minimizes risks of blood clots and excessive bleeding while significantly reducing equipment size and complexity—making it ideal for battlefield conditions.
If successful, GOLDEVAC will act as a medical force multiplier, allowing for enhanced care even in remote missions or large-scale conflicts against technologically advanced adversaries.
Overcoming Infrastructure Challenges
Historically, U.S. warfighters benefited from robust medical evacuation infrastructure, enabling rapid access to surgical care within the golden hour. However, future large-scale combat operations (LSCOs) may lack such infrastructure, extending evacuation timelines well beyond an hour. This creates an urgent need for innovative solutions like GOLDEVAC that can extend the golden hour into a more flexible and lifesaving “Golden Window.”
GOLDEVAC addresses these challenges by enabling advanced casualty care near the point of injury, throughout evacuation, and until patients reach higher levels of care. As Lt. Col. Adam Willis, GOLDEVAC’s program manager, explains, the initiative ensures that injured service members are stabilized effectively during every stage of the evacuation process.
By integrating advanced gas exchange and resuscitation technologies, the program provides a lifeline where traditional evacuation and care options are unavailable. This capability could significantly enhance the survivability of wounded personnel during prolonged and complex missions, making GOLDEVAC indispensable for future combat scenarios.
Pathways to Adoption and Commercialization
DARPA is adopting a holistic approach to ensure GOLDEVAC’s success by fostering collaboration with government agencies, regulatory authorities, and industry partners. The program emphasizes:
- Compliance with FDA safety standards.
- Addressing ethical, legal, and societal considerations.
- Exploring commercialization pathways for broader adoption in military and civilian contexts.
By facilitating partnerships, DARPA aims to transition GOLDEVAC technologies into scalable solutions that redefine combat casualty care. These innovations could eventually be used in civilian emergency response, disaster relief, and other medical scenarios requiring portable and automated trauma care.
A Transformative Future for Combat Medicine
The GOLDEVAC program represents a paradigm shift in combat medicine, combining cutting-edge technology with battlefield practicality. By equipping medics with lightweight, automated tools, DARPA is setting the stage for enhanced care that transcends traditional limitations.
With its ability to stabilize critically injured soldiers for extended periods, GOLDEVAC ensures that lifesaving intervention is possible, even in the most challenging combat scenarios. By extending the golden hour to a golden window, this groundbreaking initiative underscores the Department of Defense’s unwavering commitment to protecting the lives of its service members while redefining the future of battlefield medicine.
