Sarah Scoles is a freelance science journalist and regular Popular Science contributor, who’s been writing for the publication since 2014. She covers the ways that science and technology interact with societal, corporate, and national security interests. The author of the books Making Contact, They Are Already Here, Astronomical Mindfulness, and the forthcoming Mass Defect, she lives in Denver and escapes to the mountains to search for abandoned mines and ghost towns as often as she can.\n
The Pentagon is looking for new ways to handle mass casualty events, and hopes that modern tech can help save more lives., we take a close look at the science and technology at the heart of the defense industry—the world of soldiers and spies.or a bomb goes off, there are often more people who need medical treatment than there are people who can help them. That mismatch is what defines a mass casualty incident.
Freeman’s organization is currently managing an assessment, mandated by Congress, of the National Medical Disaster System, which was set up in the 1980s to manage how the Department of Defense, military treatment facilities, Veterans Affairs medical centers, and civilian hospitals under the Department of Health and Human Services respond to large-scale catastrophes, including combat operations overseas.
Jean-Paul Chretien, the Triage Challenge program manager at DARPA, does have some specific hopes for what will emerge from this risk—like the ability to identify victims who are more seriously injured than they seem. “It’s hard to tell by looking at them that they have these internal injuries,” he says. The typical biosignatures people check to determine a patient’s status are normal vital signs: pulse, blood pressure, respiration.
For her part, Shackelford is interested in seeing teams incorporate a sense of time into triage—which sounds obvious but has been difficult in practice, in the chaos of a tragedy. Certain conditions are extremely chronologically limiting. Something fell on you and you can’t breathe? Responders have three minutes to fix that problem. Hemorrhaging? Five to 10 minutes to stop the bleeding, 30 minutes to get a blood transfusion, an hour for surgical intervention.
But it won’t be easy: The agency’s description of the scenarios says they might involve both tight spaces and big fields, full light and total darkness, “dust, fog, mist, smoke, talking, flashing light, hot spots, and gunshot and explosion sounds.” Victims may be buried under debris, or overlapping with each other, challenging sensors to detect and individuate them.
