Berlin ARDS Classification Calculator (magent)
x402
Berlin ARDS Classification Calculator (magent) 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).
Applies the Berlin 2012 definition to classify Acute Respiratory Distress Syndrome (ARDS) as none, mild, moderate, or severe based on caller-supplied clinical flags and PF ratio.

How this service works
Berlin Definition of ARDS (Ranieri 2012). berlin_ards iff clinical box (onset within 1 week, bilateral opacities not fully explained, origin not fully HF or fluid) and severity mild, moderate, or severe. Severe: PF<=100 with PEEP>=5. Moderate: 100<PF<=200 with PEEP>=5. Mild: 200<PF<=300 with PEEP or CPAP>=5. Caller assigns flags and pf_ratio. magent does not read radiographs or echo, diagnose ARDS, or set ventilator mode. Not AECC 1994, not Kigali, not the oxygenation index.
Output
Returns a Berlin ARDS classification result indicating whether the patient meets the clinical box criteria and, if so, the severity tier: mild (PF 200–300 with PEEP/CPAP ≥5), moderate (PF 100–200 with PEEP ≥5), or severe (PF ≤100 with PEEP ≥5), or no ARDS if clinical box criteria are not met.
Example use cases
ICU ARDS severity stratification
“I have an ICU patient with onset of respiratory symptoms within 1 week, bilateral opacities not fully explained by other causes, no cardiac failure explanation, PEEP of 8, and a PF ratio of 180. Can you classify their ARDS severity using the Berlin 2012 criteria?”
Severe ARDS eligibility check
“Check if this patient qualifies for severe ARDS under the Berlin definition — onset within 1 week is true, bilateral opacities not fully explained is true, origin not fully HF or fluid is true, PEEP is at least 5, and their PF ratio is 85.”
Mild ARDS on CPAP documentation
“My patient is on CPAP at 6 cm H2O (not PEEP), has a PF ratio of 260, onset within 1 week, bilateral opacities not fully explained, and the origin is not cardiac or fluid related. Does this meet Berlin criteria for mild ARDS?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/berlin_ardsWhen to prefer
Use this endpoint when you need a fast, deterministic application of the Ranieri 2012 Berlin ARDS definition in a clinical decision support or documentation workflow. It is appropriate when the caller has already interpreted radiology, echocardiography, and clinical history and needs only the formal severity classification computed. Prefer this over manual lookup when integrating ARDS scoring into automated ICU dashboards or EHR pipelines. Do not use if you need the older AECC 1994 definition, the Kigali modification, or the oxygenation index — those are explicitly out of scope.
Side effects
- Missing required query parameters (onset_within_1_week, bilateral_opacities_not_fully_explained, origin_not_fully_hf_or_fluid, peep_ge_5, cpap_ge_5, pf_ratio) return a validation error
- PF ratio outside the accepted range (20–800 mmHg) may be rejected or yield unexpected results
- Misconfigured boolean flags (e.g., treating string 'true' as boolean) may cause schema validation failure
- Payment not provided or invalid x402 credentials result in a 402 Payment Required response
- Caller misattributes CPAP-only as satisfying moderate/severe PEEP requirement — the API correctly requires PEEP ≥5 for those tiers
