# BSH Plasma Volume Calculator (No Bleeding)

> BSH Plasma Volume Calculator (No Bleeding) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Calculates starting fresh frozen plasma dose (mL) for adults without major bleeding using the BSH 2018 formula: 15 mL/kg body weight.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bsh-plasma-volume-calculator-no-bleeding-a62dd1b7
```

Example prompt: Using the BSH 2018 guideline, what is the starting plasma dose in mL for an adult patient weighing 72 kg with no major bleeding?

## When to prefer this

Use this endpoint when you need a quick, deterministic, guideline-cited starting plasma volume calculation for an adult patient without major bleeding. Prefer it over manual calculation to ensure citation traceability to BSH Green 2018. Do not use for major haemorrhage protocols, paediatric dosing, or product/ABO group selection.

## Known failure modes

- weight_kg outside valid range (1–500 kg) returns an error
- missing weight_kg parameter returns a validation error
- non-numeric weight_kg value returns a schema validation error
- payment not included or insufficient returns 402 Payment Required

## How this service works

Starting plasma volume without major bleeding: volume_ml = 15 * weight_kg (BSH Green 2018). Adult 15 mL/kg only. Not a transfusion order, major-haemorrhage protocol, or product order. magent does not choose a product or ABO group. Deterministic published arithmetic with citation.

## Output

Returns a computed plasma volume in millilitres calculated as 15 × weight_kg, with citation to BSH Green 2018. Does not recommend a blood product, ABO group, or transfusion order — just the arithmetic dose.
