# Pizov 1999 Blast Lung Injury Severity Calculator

> Pizov 1999 Blast Lung Injury Severity Calculator 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).

Classifies blast lung injury severity (mild, moderate, or severe) per Pizov 1999 criteria using caller-supplied PaO2/FiO2 ratio, infiltrate pattern, pneumothorax status, and bronchopleural fistula status.

## 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 pizov-1999-blast-lung-injury-severity-calculator-7b28bc1a
```

Example prompt: My patient had a blast injury — their PaO2/FiO2 ratio is 140 mm Hg, I'm seeing diffuse infiltrates on imaging, no pneumothorax, and no bronchopleural fistula. Can you run the Pizov 1999 blast lung injury severity classification?

## When to prefer this

Use this endpoint when you need a strict, rule-based Pizov 1999 blast lung injury severity classification grounded in a published clinical definition. It is appropriate only when the caller has already independently determined all clinical findings (PF ratio, infiltrate pattern, pneumothorax, bronchopleural fistula) and wants to map them to a severity grade with exact-match validation. Do not use it to interpret raw imaging or blood gas values — it does not read radiographs or assay blood gas. Prefer this over generic severity tools when documentation or decision support must be traceable to the Pizov 1999 publication.

## Known failure modes

- Inputs do not match any Pizov 1999 definition — combination rejected
- PaO2/FiO2 ratio outside accepted range (20–600) returns validation error
- Missing required query parameters returns 400-class error
- Bronchopleural fistula true for mild or moderate grades causes rejection
- Pneumothorax true for mild grade causes rejection

## How this service works

Pizov 1999 blast lung injury severity. Mild, moderate, or severe only when inputs match a published definition: mild PaO2/FiO2 > 200, localized infiltrates, no pneumothorax; moderate 60 to 200, diffuse infiltrates, with or without pneumothorax; severe < 60, bilateral infiltrates, and bronchopleural fistula. Unmatched combinations are rejected. Caller assigns all findings. magent does not read a chest radiograph or assay blood gas. Not a ventilator prescription.

## Output

Returns the Pizov 1999 blast lung injury severity grade (mild, moderate, or severe) when the supplied combination of PaO2/FiO2 ratio, infiltrate pattern, pneumothorax, and bronchopleural fistula exactly matches a published definition. Unrecognized or inconsistent combinations are rejected with an error rather than a best-guess grade.
