Implementing DEMS

Establish DEMS without building an aviation organisation.

Everdrone provides the aircraft, bases, software, approvals, flight operations and training. Your organisation keeps clinical governance and decides when a DEMS resource is dispatched.

Roles and responsibilities

Healthcare governs the medicine. Everdrone runs the system.

Each side does what it is built for. Your organisation keeps clinical governance. Everdrone takes responsibility for everything needed to put a DEMS resource in the air.

Everdrone

System provider

Before go-live

DEMS bases, aviation approvals, airspace coordination, dispatch and LiveView integration

At the 112 call

The alarm reaches the Everdrone DEMS system and the aircraft launches automatically

Flight and delivery

A flight supervisor supervises every mission. The AED is lowered by winch close to the patient

On scene and after

Maintenance, monitoring, support and performance reporting

Everdrone does not set clinical protocol.

Delivered as a service

Built into the workflow you have

Everdrone runs the aircraft, DEMS bases, flight supervision, maintenance and support. Your organisation needs no drone pilots.

A DEMS resource is dispatched automatically alongside the ambulance, with no extra step at the dispatch desk. The dispatcher's task is to guide the bystander once the AED has landed, and DEMS Academy trains dispatch teams for exactly that.

Built for public procurement

Defined service levels

What the service delivers, and when, agreed before operation starts.

An implementation plan

From DEMS base installation to acceptance tests, with clear responsibilities.

A security and privacy package

The documentation procurement and information security teams ask for.

Performance reporting

Against agreed measures such as Mission Availability and alarm-to-usable payload.

Start with a feasibility study

Know where DEMS creates value before you deploy it

A feasibility study uses DEMS GridPlanner™ to analyse your historical emergency calls, ambulance response times, population and geography, and simulates DEMS missions to real incident locations. It also maps airspace, integration and evidence needs.

You receive

Recommended DEMS base positions and expected coverage

Expected time advantage over ground response, by area

Expected mission volume by emergency type

Integration, airspace and privacy assessment

A decision basis for leadership, funding and procurement

How GridPlanner works

Add DEMS bases. Watch coverage change.

Illustrative Illustrative map of simulated emergency calls in a fictional region. Dots inside a DEMS base's reach turn dark as bases are added.

Each dot is a simulated emergency call in a fictional region. GridPlanner places each new DEMS base where it reaches the most calls not already covered. A feasibility study does the same with your own historical calls, response times and geography.

From feasibility to operation

Four phases, one system

1

Phase 1

Feasibility study

Network design, local workflow, airspace, integration and evidence plan.

2

Phase 2

Implementation

DEMS bases installed, dispatch and LiveView integration tested, approvals in place, staff trained through DEMS Academy, acceptance tests passed.

3

Phase 3

Operation

DEMS resources in daily dispatch, with performance reported against agreed measures such as Mission Availability and alarm-to-usable payload.

4

Phase 4

Development

New areas, new bases and new DEMS applications added on the same system.

Every new DEMS base in an existing network reuses the integration, governance and training already in place.

Questions by role

What people ask before they start

Do we need to build a drone organisation?

No. Everdrone provides the aircraft, DEMS bases, software, approvals, flight supervision, maintenance and training. Your organisation keeps clinical governance and decides when a DEMS resource is dispatched.

Does DEMS replace ambulances or volunteer responders?

No. A DEMS resource is dispatched alongside them. It complements ground EMS and HEMS.

How do we start?

With a feasibility study on your own emergency call data, which shows where DEMS bases should be positioned and what they can achieve.

Who decides when DEMS is dispatched, and with what?

The healthcare provider. You define the dispatch criteria, the DEMS applications and the medical payloads.

Does the AED actually get used?

That depends on the dispatch workflow. After dispatcher training, 50% of drone-delivered AEDs were attached in cases with bystander CPR, up from 27%. (Resuscitation Plus, 2026)

How much earlier does it arrive?

In a 2025 study in western Sweden, the DEMS resource was first or the only resource on scene in 98% of completed missions, with a median arrival time of 4 min 24 s against 8 min 50 s for ground units. (BMC Emergency Medicine, 2026)

Does DEMS add work during the call?

The DEMS resource is triggered from your existing dispatch system. Your task is to guide the bystander to the AED once it is delivered.

What do we see?

LiveView of the scene. In a 2025 study, live video reached the dispatch centres in every completed mission. (BMC Emergency Medicine, 2026)

How are we trained?

Through DEMS Academy.

Why is a drone flying over my street?

A DEMS resource is on its way to someone nearby who has called 112 and needs urgent help.

A defibrillator has been delivered. What do I do?

Bring it to the patient and follow the voice instructions. The 112 operator will guide you. The defibrillator only gives a shock if one is needed.

Is it safe?

Every mission is supervised by a trained flight supervisor, and no adverse events were reported in the published studies of live operations.

Start with your own data

A feasibility study uses your own emergency call data to show where DEMS resources should be positioned and what they can achieve.
