Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum Gajic 2011 Table 3 lung injury prediction score items from caller-assigned flags and return the published ROC cutoff band (low <4, high ≥4).

When to use

When an agent needs the published LIPS point total and must not invent an ARDS diagnosis or additional cut-points.

When not to use

  • Not a medical device. Not an ARDS diagnosis. magent does not examine the patient or read imaging; every flag is caller-assigned.
  • Gajic 2011 Table 3 worksheet only. At most one high-risk surgery type (orthopedic_spine, acute_abdomen, cardiac, aortic_vascular) may be true.
  • Emergency surgery adds 1.5 in addition to the surgery type (footnote *). Diabetes mellitus subtracts 1 only when sepsis is true (footnote †); diabetes without sepsis scores 0.
  • Bands are low (score <4) and high (score ≥4) from the paper ROC cutoff. No other cut-points are returned.
  • max_score 15.5 is the published observed range in Gajic 2011, not a theoretical sum of every Table 3 row.

Formula

LIPS = shock(2) + aspiration(2) + sepsis(1) + pneumonia(1.5) + at most one of orthopedic_spine(1), acute_abdomen(2), cardiac(2.5), aortic_vascular(3.5) + emergency_surgery(1.5) + traumatic_brain_injury(2) + smoke_inhalation(2) + near_drowning(2) + lung_contusion(1.5) + multiple_fractures(1.5) + alcohol_abuse(1) + obesity_bmi_gt_30(1) + hypoalbuminemia(1) + chemotherapy(1) + fio2_gt_035(2) + tachypnea_rr_gt_30(1.5) + spo2_lt_95(1) + acidosis_ph_lt_735(1.5) + diabetes_mellitus(-1 only if sepsis); Gajic 2011 Table 3; published observed range 0-15.5; low <4, high >=4

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/lips Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

  • 1 to 25 items. Each item uses the same keys as the GET query parameters.
  • POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
  • The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
  • HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
  • Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
  • x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Response

Field Type Description
formula string lips
formula_expression string Exact expression used
score number LIPS points as a number (0.0, 1.5, 7.5, …). Half-points are allowed.
max_score number 15.5 is the Gajic 2011 published observed upper range, not a sum of every Table 3 row.
lips_band string Gajic 2011 ROC cutoff: low when score <4, high when score >=4. Not an ARDS diagnosis. No other cut-points.
components array Per-factor points
citation object Gajic et al. AJRCCM 2011 citation
disclaimer string Not-a-device notice

HTTP Code When
400 invalid_flag boolean clinical flags must be true or false Returned before settlement; you are not charged.
400 invalid_lips_surgery at most one high-risk surgery type may be true: orthopedic_spine, acute_abdomen, cardiac, or aortic_vascular (Gajic 2011 Table 3). Returned before settlement; you are not charged.
400 invalid_items POST body must be a JSON object with only an items array Returned before settlement; you are not charged.

  • Berlin Definition of ARDS — Apply the 2012 Berlin Definition of ARDS and return whether the clinical box holds, severity (none, mild, moderate, or severe), and berlin_ards.
  • Murray lung injury score — Mean the four Murray 1988 lung injury score components (chest radiograph quadrants, PaO2/FiO2, PEEP, and compliance), each 0–4, and return LIS and injury_band.
  • PaO2/FiO2 ratio — Compute the PaO2/FiO2 ratio as arterial PO2 in mm Hg divided by inspired oxygen fraction.

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

  • HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
  • exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
  • HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
  • Execution is timeout-bounded and concurrency-capped.
  • Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
