What does AED delivery before EMS arrival mean?
AED delivery before EMS arrival describes an equipment-access objective, not proof that an AED was used or that a patient benefited. MARDE Inc. in New Jersey is developing a proposed aerial-and-ground supply-delivery concept. It remains pre-prototype, with no deployed systems, announced commercial pilots or validated full-system performance results.
MARDE Inc. is based in New Jersey, USA. It is pre-seed, pre-prototype and pre-revenue, with no deployed systems or announced commercial pilots. These pages describe development objectives and proposed evaluation questions, not equipment available for purchase or a live emergency-response service.
Which events should an evaluation distinguish?
A delivery evaluation should define its starting event and endpoint before collecting times. Aircraft arrival, payload placement, equipment retrieval and EMS handoff are distinct events. A package can reach the scene while remaining inaccessible to the intended receiver. Recording those events separately makes the actual limitation visible and helps prevent a transport result from becoming a broader claim.
An agency should also ask which incidents were eligible, which missions could not start and which attempts were abandoned. A fast successful attempt gives an incomplete picture if availability, recovery and failures are omitted. Local comparison data must use compatible definitions rather than treating every published response-time number as interchangeable.
What does external drone-AED research establish?
Published drone-AED literature includes observations from particular systems and settings. Reading it requires attention to the measured endpoint: transport, receipt, use and patient outcomes should not be collapsed together. MARDE's research article links primary literature and discusses how to keep each conclusion tied to the source that supports it.
CARES registry findings help explain the broader response-gap discussion. They are not MARDE mission measurements. Subtracting a hypothetical robot travel time from an EMS registry median would not establish a patient benefit or a local operational advantage. MARDE has not performed the full-system or clinical evaluation needed to support such a claim.
How would MARDE investigate delivery and final access?
Air would carry and lower Ground into a cleared outdoor area. A human would direct Ground movement and authorize dispensing, with Nexus coordinating status and scene information. Initial exercises would use a training AED and packaged training supplies. Robotic AED electrode placement, CPR and direct tourniquet application are outside V1.
The combined approach adds a possible outdoor access stage after aircraft arrival, but also introduces extra mass, handoffs and communication dependencies. Those are tradeoffs to investigate. MARDE does not claim the architecture is faster than an aerial-only system or appropriate for every scene. Indoor access and stair climbing are deferred.
What would a controlled receiving exercise measure?
A proposed training exercise could define a receiving area, a packaged training payload and a participant role. Observers would record whether the receiver understood the notification, located the equipment and received it without unplanned assistance. The exercise would need a recovery plan and explicit stop conditions. This describes a proposed evaluation, not a completed MARDE result.
Changing the receiver's location, interrupting communication or making the receiving area unavailable can reveal assumptions hidden in an ideal demonstration. Any prompting or physical assistance should be recorded. A successful exercise under cleared, supervised conditions would support a narrowly stated engineering observation, not readiness for untrained bystanders at real emergencies.
Who should be involved before operational evaluation?
The requirements discussion should include agency operational staff and appropriate clinical, aviation and information-governance expertise. They would need to define responsibility for the aircraft, the ground stage, equipment receipt and the professional handoff. Technical feasibility alone does not settle permissions, staffing, clinical use or liability.
MARDE invites requirements conversations and research critique, with no expectation that an agency commit to equipment. Useful input includes de-identified access scenarios, receiving roles and evaluation constraints. The website is an information channel rather than a live dispatch or medical-assistance service. Contact does not enroll anyone in a clinical study or operational pilot.
