# Cath Copilot > A local-first, chat-first desktop copilot for the cardiac catheterisation lab. Pre-case flags, a live in-room timeline, reconciliation, a cited procedure-note draft, handover, and audit, with every fact cited and every action confirmed by a person. Recommend, draft, route. Cath Copilot sees only what the signed-in clinician may see, cites every fact to its source record, and never changes anything without a confirmation. The AI runs on the machine, so nothing leaves the hospital network. Who it's for: Interventional cardiology teams: operators, nurses, physiologists, radiographers, coordinators, quality leads, and the IT and information-governance staff who deploy for them. Status: Pilot. Cath Copilot is offered as a pilot to departments; book a demo at hi@zapxlabs.com. There is no public download. ## How it works - Sign in with your hospital account. Your role decides what you can see; a nurse sees planned access but not order details, a radiographer cannot open the medication chart, and break-glass access is audited. - Ask the copilot what needs attention or open a case. Pre-case flags come from deterministic local rules, the in-room timeline validates events as they arrive, and reconciliation catches values where sources disagree. - Draft the procedure note, the audit return, and the handover from the record with a citation on every sentence. Signing locks when a statement has no support. Actions arrive as cards you confirm; nothing changes on its own. ## What it does - Chat-first workspace with agents for readiness, in-room, notes and coding, handover, results, and implant recall - Pre-case brief with a source on every field and rule-based flags to resolve, assign, or escalate - Live in-room timeline with event validation and display-only haemodynamics - Reconciliation, a cited procedure-note draft, claim-support check, sign-off, and export - National audit return pre-filled from the record and code suggestions with their evidence - Cited handover to CCU, recovery, or ward, acknowledged by the receiving nurse - Results and follow-up loop closure, and implant recall search across all cases - Role-based access, break-glass with a reason, and an append-only hash-chained audit log - Connects to FHIR, DICOMweb PACS, HL7 v2 over MLLP with TLS, and IEEE 11073 SDC devices - Local AI through Ollama; runs solo on one PC, as a lab host, or against a hospital server ## Key pages - [Cath Copilot](https://cathcopilot.zapxlabs.com/): overview, demo video, screenshots and FAQs - [Cath Copilot on zapxlabs.com](https://zapxlabs.com/products/cath-copilot) - [Guides](https://cathcopilot.zapxlabs.com/guides): 11 plain-English guides for cath lab managers, quality leads and interventional teams, with official sources checked October 2026 - [Demo video](https://rd8wcxopkzqdtty4.public.blob.vercel-storage.com/products/cath-copilot-walkthrough.mp4): A day in the cath lab on synthetic data: ask what needs attention, clear pre-case flags with their sources, validate the in-room timeline, reconcile a value two systems disagree on, sign a cited note, send the handover and check the audit log. ## Guides - [How to write a cath lab procedure report](https://cathcopilot.zapxlabs.com/guides/cath-lab-procedure-report): What a cardiac catheterisation procedure note should contain, why dose belongs in it under IR(ME)R, and how to keep it consistent with the audit. - [What goes in a cath lab procedure log](https://cathcopilot.zapxlabs.com/guides/cath-lab-procedure-log): The events a cath lab procedure log should capture, where each comes from, and how to validate them before they reach the note. - [The national PCI audit (NAPCI) and BCIS explained](https://cathcopilot.zapxlabs.com/guides/napci-bcis-pci-audit): What the National Audit of Percutaneous Coronary Interventions collects, who runs it, BCIS's role, and why units are expected to take part. - [Radiation dose recording in the cath lab under IR(ME)R](https://cathcopilot.zapxlabs.com/guides/radiation-dose-recording-cath-lab): What IR(ME)R 2017 requires on recording patient dose for cath lab procedures, which values to record, and how to keep them consistent. - [Diagnostic reference levels in the cath lab](https://cathcopilot.zapxlabs.com/guides/diagnostic-reference-levels-cath-lab): Why there's no national DRL for coronary angiography or PCI, what UKHSA does list, and how cath labs set and review local DRLs. - [Significant accidental or unintended exposures (SAUE) in the cath lab](https://cathcopilot.zapxlabs.com/guides/saue-reporting-cath-lab): What counts as an accidental or unintended exposure under IR(ME)R, when to notify CQC, and what it means for cath lab teams. - [Cath lab inventory: scanning devices at the point of use](https://cathcopilot.zapxlabs.com/guides/cath-lab-inventory-and-implant-scanning): What NHS Scan4Safety and GS1 requirements mean for cath lab inventory, and why scanning stents and devices into the case record matters. - [Implant traceability and recall: UDI, registries and the cath lab](https://cathcopilot.zapxlabs.com/guides/implant-traceability-and-recall): Where UDI stands in Great Britain, what the Medical Devices Outcomes Registry requires, and how to make implant recalls fast. - [NatSSIPs in the cath lab: safety checks for invasive procedures](https://cathcopilot.zapxlabs.com/guides/natssips-cath-lab): How NatSSIPs 2 applies to cath labs, the sign in, time out and sign out steps, and how pre-case checks fit around them. - [Cath lab handover to recovery, CCU or the ward](https://cathcopilot.zapxlabs.com/guides/cath-lab-handover): What a structured handover from the cath lab should cover, what NatSSIPs says about handovers, and how to close the loop with acknowledgement. - [Using AI in the cath lab without sending data off site](https://cathcopilot.zapxlabs.com/guides/local-ai-in-the-cath-lab): What NHS guidance says about cloud and data security, and what to ask before using AI for cath lab documentation and audit. Note: Cath Copilot is a prototype running on synthetic data only. It is not a medical device and is not for clinical use. It recommends, drafts, and routes; it never diagnoses, orders, or decides. A clinical safety and information-governance process precedes any use with real patient data. Made by Zapx Labs (https://zapxlabs.com).
