Systemic Vascular Resistance Calculator (SVR)

Compute SVR = 80 × (MAP − CVP) / CO (dyn·s/cm⁵). Normal 800–1440; high in cardiogenic shock and hypertension; low in distributive shock and vasodilators. Derived from Grossman 1991, StatPearls, LITFL, Vincent NEJM 2013, Braunwald. Not medical advice.

Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'https://api.elysiatools.com/en/api/tools/systemic-vascular-resistance' \
  -H 'Content-Type: application/json' \
  -d '{"map":93,"cvp":8,"co":5,"decimalPlaces":0}'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/systemic-vascular-resistance

Parameters

Name	Type	Required	Description
map	number	Yes	Mean arterial pressure (mmHg). If unknown, MAP = DBP + (SBP − DBP)/3.
cvp	number	Yes	Central venous pressure (mmHg) from a central line; approximates right atrial pressure. Typical 2–8 mmHg.
co	number	Yes	Cardiac output in L/min (from thermodilution, Fick, or echo).
decimalPlaces	number	No	—

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

  "mcpServers": {
    "elysiatools-systemic-vascular-resistance": {
      "name": "systemic-vascular-resistance",

      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "systemic-vascular-resistance",
    "arguments": {
  "map": 93,
  "cvp": 8,
  "co": 5,
  "decimalPlaces": 0
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
