01 — Critaxis · Helsinki, Finland
Critaxis replaces the paper triage card with an offline-first mobile platform for triage, field documentation and patient handover in demanding operations.
In development. Field requirements are being defined with clinicians and operators now.
Contact02 — The gap
Hospitals have electronic records. Command rooms have coordination tools. The field still starts with a marker, a paper tag and a radio call.
87%
of combat casualty deaths occur before the patient reaches a medical treatment facility.
<10%
of 30,000 casualties in Iraq and Afghanistan had any documentation of prehospital care in their medical records.
67%
of communication errors in hospitals are related to patient handoff.

Paper tags are destroyed by weather, saturated in blood, or lost in transfer. When the tag is lost, the next clinician starts from zero.
03 — The platform
Critaxis is built around a digital patient card that follows the casualty from first contact to the next handover. It guides the user through triage, key observations, injuries, treatments and status changes, producing a structured record without turning urgent care into an administrative task.
The platform adapts to the user. A basic responder records only the essentials. Trained clinicians reach deeper modules for treatment, medication and continued care.
Data moves device to device over a local mesh, or securely over a network when one exists. In connected use, the same records assemble a live operational picture of patient counts, priorities and care status.
No new hardware. No dependency on infrastructure that may not be there.
04 — How it is built
01
Architected for full clinical function with zero connectivity, syncing opportunistically when a path appears. The hard problem is resolving concurrent edits made by devices that have been apart, and it is designed for from the start rather than retrofitted.
02
Built to move data device to device across whatever exists: BLE, peer-to-peer Wi-Fi, LAN, with hooks for tactical IP radio and low-bandwidth links. Data routes hop by hop toward a connected gateway.
03
Structured around MARCH and standard triage categories rather than bolted onto a generic form. Status changes are designed to propagate as compact events, not documents.
04
Targeting FHIR as the native record format, AJMedP-5 for military exchange, HL7 v2 for legacy estates. The field record should arrive as data the receiving system already understands.
05
Designed to convert medical events into Cursor on Target for existing situational-awareness stacks, so a triage category set in the field appears on the map command is already watching.
06
On-device inference to flag deterioration trends and reduce cognitive load under stress, degrading gracefully to plain clinical reference when sensor input is unavailable.
05 — Operating environments
Casualty documentation and evacuation prioritisation in contested, infrastructure-denied environments.
Pre-hospital documentation and handover into the receiving hospital record.
Structured triage and patient tracking across multi-agency response.
Medical documentation where evacuation times are long and connectivity is not assumed.
Requirements are drawn from operators working in current European operations and from clinicians in emergency and field medicine. The product is designed against how these environments actually behave, not how they are specified.
06 — Market
The bottleneck is identical on both sides of the line. The same communication failures, triage inaccuracies and patient tracking gaps that degrade military operations also degrade civilian mass casualty response.
$42.8B
projected global defence emergency medicine market by 2033, growing at 20.4% CAGR from 2025.
$196.2B
forecast global incident and emergency management market by 2030, from $129.2B in 2024.
13.27%
projected CAGR of the software segment of military telemedicine through 2035, the fastest-growing part of that market.
Critaxis operates a freemium, land-and-expand model. The core application is free, which removes the adoption barrier at the individual responder. Organisations pay for secure data transfer, shared situational awareness, advanced clinical modules, user management and integrations.
07 — Team
Critaxis is founded by people who have created critical patient data under pressure in the field, and people who have built systems reliable enough to be trusted with it.
The requirements come from practice, not from research. Our clinical lead works in an emergency department, instructs tactical casualty care, and sits on the board of the Finnish Tactical Medicine Association. Our preparedness lead has fifteen years across emergency medical services, rescue services and demanding security environments. The people this is built for are the people we already work alongside, and they tell us when it is wrong.
That is the part that is hard to copy. Writing software gets easier every year. Knowing precisely what a responder can capture with one hand, in the dark, at minute three, and being trusted enough to have it adopted, does not.
