    Company

    A company built around emergency cardiovascular care and responsible clinical AI.

    PathFree Technologies is developing AiMediQ™, an AI-enabled Code Blue support system powered by datasyteAI™, designed to help clinical teams coordinate the critical actions of in-hospital cardiac arrest — supporting qualified clinicians, never replacing them.

    Why PathFree exists

    In-hospital cardiac arrest is a coordination problem as much as a clinical one.

    PathFree was founded to close a specific gap: qualified clinical teams doing everything right, under extreme time pressure, without a purpose-built coordination and documentation surface. That gap has consequences — for outcomes, for teams, and for institutional learning. Our work exists to help close it.

    We are a multidisciplinary team of clinicians, regulatory specialists, technologists, and operators. We build carefully. We label our claims honestly. We measure success at the bedside and in the record.

    Operating principles

    How we build.

    Five principles shape day-to-day decisions across product, evidence, and communication.

    Clinician-centered design

    Every decision starts with the resuscitation team. The system supports qualified clinicians; it does not replace them.

    Evidence before claims

    We publish only what has been approved. Planned work stays labeled as planned until data, review, or regulatory status supports otherwise.

    Safety by design

    Safety is a property of architecture and process — not a slogan. Scope, governance, and change control are built in.

    Workflow integration

    Adopted well means adopted at the bedside. We design to fit existing resuscitation workflow and documentation practice.

    Transparent governance

    Regulatory status, evidence maturity, and integration items are labeled honestly, including when the answer is “not yet.”
