Elevator Pitch
Sempulse’s FDA-cleared Halo monitor applies in seconds to the back of the ear and neck, and continuously monitors vital signs non-invasively during motion, in full-gear, and in the most austere environments on earth, from the point of injury through every role of care. SpO2, pulse rate, respiratory rate, core and skin temperature are live within 15 seconds. Cuffless blood pressure, ECG, and the Army’s best hemorrhage prediction algorithm are coming next.
Halo’s data streams in real-time to a medic’s tablet running LiveCharts, to ATAK, BATDOK®, and NGC2, and simultaneously to remote physicians, automatically generating the DD Form 1380 and 9-Line MEDEVAC so the medic never has to stop caring for patients to do paperwork.
Today, medics manually take vital signs one at a time, one patient at a time, subjectively decide who needs help first, and then spend critical minutes on documentation. Halo monitors an unlimited number of casualties simultaneously, objectively ranks them by severity every second, and automates the paperwork so medics can do what they’re trained to do: save lives.
Validated on the battlefield and in multiple field exercises. FDA-cleared, with more clearance on the way. TRL 9. Available now.
Concept
51.4% of U.S. soldiers killed in Iraq and Afghanistan died of potentially survivable causes. Not from wounds that couldn’t be treated, but from wounds that weren’t treated in time.
The same problem plays out in today’s military and every day in civilian life. Mass casualty events overwhelm first responders who have no way to rapidly locate and prioritize the wounded. Multi-vehicle accidents leave patients waiting because there aren’t enough ambulances. Outpatient surgical volumes are doubling. An aging Baby Boomer population is straining nursing home care capacity to its limits. In every one of these scenarios, the limiting factor is the same: no one knows who needs help most, right now.
Sempulse was built to solve that. The Halo monitor applies in seconds to the back of the ear and neck, leaves the wearer in full gear with full mobility and full sensory awareness, and begins streaming clinically actionable vital signs within 15 seconds, continuously, non-invasively, and accurately enough to meet FDA standards for trauma care. An unlimited number of patients can be monitored simultaneously and automatically ranked by severity every second, so medics, physicians, first responders, and nurses can focus entirely on care instead of assessment.
From the battlefield to the emergency room to the nursing home to the highway, the constraint has never been the willingness to save lives. It has been the ability to know, in real-time, whose life needs saving first.
