On the battlefield
Medics make life-and-death decisions with limited diagnostics and minimal resources — often far from surgical care, in exactly the austere environments where hemorrhage kills fastest.
Operation Lifeblood unites military medicine, first responders, and trauma science to build physics-first digital twins of the failing circulation — predictive, field-ready tools that turn survivable shock from a leading killer into a treatable condition, from point of injury to definitive care.

Our mission is to eliminate preventable death from trauma and hemorrhagic shock by advancing innovative research, developing field-ready treatments, and rapidly translating military medical breakthroughs into lifesaving solutions.
We focus on the full continuum of care — from point of injury, through evacuation and resuscitation, to definitive treatment — and we build our tools as public-good research infrastructure, open to the military and civilian trauma systems that need them.
A world where survivable shock is no longer fatal.
Core values
Uncontrolled bleeding remains the leading cause of preventable death after traumatic injury, in combat and at home — not because the deaths are unavoidable, but because the tipping point into irreversible shock is recognized everywhere and predicted nowhere.
Medics make life-and-death decisions with limited diagnostics and minimal resources — often far from surgical care, in exactly the austere environments where hemorrhage kills fastest.
EMS crews and emergency departments face unpredictable scenes, long transports, and variable access to blood and surgical capability. The physiology — and the clock — are the same.
Academic labs are siloed and publication-driven, industry lacks a near-term product pathway, and grants fragment the problem across subsystems. No institution owns end-to-end delivery.
"Irreversible shock" is a recognized clinical reality — the moment resuscitation stops working — but it emerges from six tightly coupled physiological subsystems that no monitor, score, or clinician can integrate in real time. Predicting it is a systems problem. That is precisely what a digital twin is for.

The FRO model exists for problems too big for a single lab and unowned by industry: a mission-bound nonprofit with dedicated staff, milestone discipline, and the freedom to build what the field needs rather than what a grant cycle rewards.
One problem, pursued with dedicated staff and single-minded execution — not a portfolio of loosely related grants.
Clinicians, modelers, engineers, and operators in one organization, spanning military and civilian trauma systems.
Quarterly milestones with go/no-go gates and independent, external validation & verification at every phase.
Models, data standards, and benchmarks built as shared infrastructure — success is measured in mortality reduction, not publication volume.
Our digital twins are grounded in the physics and physiology of the circulation — models that conserve mass and momentum, respond plausibly to perturbation, and carry calibrated uncertainty. High-fidelity models become fast reduced-order models that couple to real sensors and run in real time at the point of injury — trustworthy enough for medicine, fieldable enough for austere environments.
Flagship
A predictive, physics-first digital twin of the heart and circulation under hemorrhagic shock — high-fidelity models distilled into fast reduced-order models that couple to sensors, forecast trajectory, and flag the tipping point before it is crossed.
Translational
Decision-support tools tuned for austere, point-of-care environments — putting twin-driven guidance in the hands of medics, EMS crews, and forward surgical teams.
Catalysis
Targeted external research catalysis for the gaps the flagship cannot internalize — funding the sensors, therapies, and science the mission needs next.
Infrastructure
Shared datasets, validation benchmarks, and standards that let the whole field build and test against common ground truth.
Operation Lifeblood works alongside the military medical community — including clinical partners at the Uniformed Services University of the Health Sciences (USUHS) — and serves as an independent verification & validation partner supporting DARPA Biological Technologies Office programs such as VITAL. As a nonprofit, OLB can hold compute, steward shared data, and run third-party V&V free of commercial conflict of interest.
Dual-use from day one: military and civilian trauma share the same physiology — every tool we field for the battlefield serves the ambulance, the ER, and the rural hospital.
Milestone-driven, with go/no-go gates and external validation at every phase. The mission doesn't end at delivery: it matures into permanent public-good infrastructure for the trauma community.
Phase 0 · 2026
Organization, governance, the technical substrate, compute partnerships, and data pipelines.
Phase 1 · 2027
A high-fidelity cardiac digital twin: heartbeat, perturbation response, conservation, physiological plausibility.
Phase 2 · 2028
Reduced-order models, sensor coupling, in-silico clinical trials, and multi-center validation.
Phase 3 · 2029
Decision-support tooling for austere care; preclinical and prospective observational alignment.
Phase 4 · 2030+
The FRO transitions into an ongoing nonprofit: training, independent V&V, standards, and enhanced diagnostics and therapies to detect and treat hemorrhagic shock in austere environments.
We are building the team, partnerships, and infrastructure to make survivable shock survivable in fact — and we want the right partners beside us.
