Post-op transfusion threshold guidance
Grounded
Query
What is our recommended transfusion threshold for stable post-op adult patients, and which sources support it?
Response
Stable post-op adults without active bleeding should generally follow a restrictive transfusion threshold of 7 g/dL. Higher targets are reserved for ischemia, persistent hypoxia, or protocol-defined exceptions. [1][2]

Features
Purpose-built for institutional clinical knowledge
MARCUS keeps the interface sparse, the retrieval pipeline explicit, and the output grounded in the material your team already trusts.
Your Protocols, Your Guidelines
Upload your institution's protocols and key papers. MARCUS aligns answers with what your hospital actually does, not generic outputs.
Knowledge Map
See how your documents relate. The concept map reveals topic clusters, content overlaps, and connections between sources.
How It Works
From upload to cited answer in three stages
The pipeline stays legible: ingest source material, retrieve the best passages, then synthesize a grounded answer with traceable citations.
Stage 1
Upload institutional knowledge
Drop in PDFs, DOCX, TXT, or HTML. MARCUS automatically chunks your documents, extracts metadata (authors, publication date, journal), generates embeddings, and indexes everything for instant retrieval.
