Ventilator Tidal Volume by PBW (ARDSNet)

Compute lung-protective VT from ARDSNet predicted body weight (PBW). Male 50+0.91×(cm−152.4); female 45.5+0.91×(cm−152.4). VT = mL/kg×PBW (4–8, default 6). Reports full range and plateau-pressure target. Derived from ARDSNet NEJM 2000, Brower 2004, StatPearls, LITFL. Not medical advice.

Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'http://127.0.0.1:3003/en/api/tools/ventilator-tidal-volume' \
  -H 'Content-Type: application/json' \
  -d '{"height":175,"sex":"male","vtPerKg":6,"decimalPlaces":0}'

API reference

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

Endpoint

HTTP

POST http://127.0.0.1:3003/en/api/tools/ventilator-tidal-volume

Parameters

Name	Type	Required	Description
height	number	Yes	Patient height in centimeters, used to derive predicted body weight (PBW).
sex	select	Yes	Sex, used to select the ARDSNet PBW formula (male base 50, female base 45.5).
vtPerKg	number	No	Tidal volume per kg of PBW. Default 6 (lung-protective); range 4 (severe ARDS) to 8 (upper bound, requires plateau pressure < 30 cmH₂O).
decimalPlaces	number	No	—

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": "ventilator-tidal-volume",
    "arguments": {
  "height": 175,
  "sex": "male",
  "vtPerKg": 6,
  "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).
