Vantra Sentinel
Clinical command · Early accessVantra Sentinel is a real-time clinical command centre for specialist consultants. It reads vital signs from any hospital system, scores every patient for deterioration, and the moment someone crosses the line it escalates — built to put the on-call consultant on the phone and capture the order, not wait for a glance at the screen.
01 / The gap
Vitals live in one system, the consultant is in another building, and the window to intervene is measured in minutes. Most monitoring platforms surface a red number and wait. By the time someone notices the screen, the moment has passed. The problem was never sensing — it was the silence between a danger sign and a decision.
A colour change escalates nothing. It hands the entire burden of response to whoever happens to be watching the board — and hopes they are.
Deterioration doesn't wait for a shift handover or a passing look at the screen. Every minute between the crossing and the response goes unmeasured and unowned.
A log anyone can edit after the fact isn't proof. When a board, a regulator or a coroner asks what happened and when, a passive dashboard cannot answer with certainty.
02 / The loop
Four movements, one closed loop — from a reading at the bedside to a verifiable order, in seconds.
Bedside monitors and hospital systems push observations over HL7 FHIR R4. Every reading is validated and available in seconds — no rip-and-replace, no bespoke integration. If your HMS speaks FHIR, Sentinel is already listening.
Each reading is scored for deterioration with NEWS2 — the Royal College of Physicians' National Early Warning Score — plus single-parameter red flags, against thresholds you set per facility. An unclear or broken reading always takes the alert path, never the silent one. An optional AI reads the trend in plain language: it can raise a concern, never hide one.
This is the part a dashboard cannot do. A breach doesn't brighten a tile and wait; it fires a governed escalation the instant it happens. The next rung — an AI voice call that states the patient, ward, vital, trend and score to the on-call consultant, captures the verbal order, and walks the ladder to a backup and the ward if no one answers — is built and arming for pilot: disarmed by default, wired per facility, gated by the same fail-closed rate limiter and kill switch that guard every outbound action on the platform.
Every reading, alert, order and acknowledgement is a governed action written to a tamper-evident, hash-chained ledger. Not a screenshot of who typed what: a chain of custody where altering any row breaks every hash after it, re-verifiable offline, and ready to hand to a regulator, an inquiry or an insurer.
03 / The difference
When a patient deteriorates
Lights up a red tile and waits to be seen.
Fires a governed escalation on breach — built to put the on-call consultant on the phone and capture the order.
The audit trail
A timestamped log that can be edited after the fact.
A hash-chained ledger — every action cryptographically provable and tamper-evident.
If no one is at the screen
The alert sits unread until someone looks.
Built to walk an escalation ladder — backup consultant, WhatsApp, then the ward.
Across facilities
One more login for every hospital.
One acuity-sorted command view, built to span every ward and facility.
Interoperability
A bespoke integration project.
FHIR R4 native — connects to the HMS you already run, no rip-and-replace.
What it actually is
A monitoring app bolted onto the ward.
One module on the platform that already runs the clinic's front desk, scribe and command centre.
04 / Governed by design
Sentinel is built on a governed data spine. The AI physically cannot take an action outside a sanctioned, audited one — no ad-hoc writes, no untraceable edits. Every clinical order is a privileged action whose audit row is written before the order itself. Governance isn’t a setting you switch on. It’s the substrate.
Reading, score, alert, order, acknowledgement — each is an entry in a tamper-evident chain, ordered and verifiable end to end.
Orders ride a fail-closed audit: the record is committed before the action. If the audit can't be written, the order doesn't happen.
Vital values, patient references and order text are encrypted on write and decrypted only at the authenticated boundary — never exposed to a browser.
Rate limits and kill switches are distributed and fail closed. The one thing the system will never do is go silent when it shouldn't.
05 / One platform
Sentinel isn’t a monitoring app you bolt on. It’s one module on the same governed platform that already answers the clinic’s phones with Concierge, documents its consultations with Scribe, and runs its operations with Central Command. The voice agent that calls the consultant is the same one that greets patients. The identity graph, the action registry and the audit chain are shared. Buy a dashboard and you own a dashboard. Deploy Sentinel and you extend an operating system you already trust.
See the platform06 / Interoperability
Sentinel connects over HL7 FHIR R4 — the global standard for clinical data exchange. If your hospital management system supports FHIR, and most modern ones do, Sentinel connects with no custom development. It augments the systems of record you already own. It never asks you to replace them.

Target: breach to the on-call consultant
FHIR R4
Native ingestion — no rip-and-replace
NEWS2
Deterioration scored on every reading
Hash-chained
Every action provable and tamper-evident
Design targets and capabilities, verified in build. Sentinel is in early-access pilot.
07 / Who it’s for
Your command centre, open on the device already in your hand. Every admitted patient on one acuity-sorted board — and a system that reaches you before a patient crashes, not after.
Digital transformation without the rip-and-replace. Sentinel plugs into your HMS over FHIR, deploys in days not quarters, and hands you an audit posture you can take to a regulator.
Raise the standard of care across a network from one governed platform. Configurable per facility, encrypted end to end, and built to scale from a single ward to a national programme.
Book a clinical briefing and we'll walk the loop end to end — a FHIR reading, a NEWS2 breach, a governed order on a tamper-evident chain — and arm the consultant call for your pilot.
