# Aldrete postanesthetic recovery score Aldrete Status: LIVE Price: $0.005 USDC `GET /api/calc/aldrete` HTML: https://magentlab.com/docs/aldrete Markdown: https://magentlab.com/docs/aldrete.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Compute the Aldrete 1970 postanesthetic recovery score as the sum of five caller-assigned 0-2 signs (activity, respiration, circulation, consciousness, color) and return the 1970 recovery-room band. ## When to use When an agent has already assigned the five Aldrete 1970 signs and needs the published 0-10 total and 0_to_7 / 8_to_9 / 10 band. magent does not examine the patient or issue a PACU discharge order. ## When not to use - Not a medical device and not a PACU discharge, ward-transfer, or monitoring order. - Each sign is a caller-supplied integer 0-2. magent does not observe activity, respiration, blood pressure change, consciousness, or color. - Aldrete 1970 five signs including color. Not the 1995 revision that replaced color with SpO2. Not Marshall-Chung PADSS. - Totals of 8 or 9 were acceptable for discharge from the recovery room to the ward; 10 is ideal; 7 or less indicated continuous close observation. That 1970 language is not a discharge order. ## Formula ``` Aldrete = activity + respiration + circulation + consciousness + color; each 0-2; max 10; 8-9 acceptable for recovery-room discharge to ward; 10 ideal; 0-7 close observation (Aldrete 1970) ``` ## Citation [A postanesthetic recovery score](https://doi.org/10.1213/00000539-197011000-00020) Aldrete JA, Kroulik D Anesth Analg. 1970;49(6):924-934 DOI: [10.1213/00000539-197011000-00020](https://doi.org/10.1213/00000539-197011000-00020) ## Worked example ### All signs 2 Given: `activity=2, circulation=2, color=2, consciousness=2, respiration=2` 1. activity 2 + respiration 2 + circulation 2 + consciousness 2 + color 2 2. Score = 10 (max 10); category 10 (ideal) ### Color 0, other signs 2 Given: `activity=2, circulation=2, color=0, consciousness=2, respiration=2` 1. activity 2 + respiration 2 + circulation 2 + consciousness 2 + color 0 2. Score = 8; category 8_to_9 (acceptable for recovery-room discharge to the ward) ### Score 7 Given: `activity=2, circulation=2, color=0, consciousness=1, respiration=2` 1. activity 2 + respiration 2 + circulation 2 + consciousness 1 + color 0 2. Score = 7; category 0_to_7 (continuous close observation) ## Also searched as - Aldrete score - postanesthetic recovery score - Aldrete 1970 - PACU recovery score - postanesthesia recovery score - recovery room score - post anaesthetic recovery - PAR score ## Parameters - `activity` (integer, required): Muscle activity (Aldrete 1970). Integer 0, 1, or 2 as assigned by the caller. 2 = moves 4 extremities voluntarily or on command; 1 = 2 extremities; 0 = none. magent does not examine the patient. - `respiration` (integer, required): Respiration (Aldrete 1970). Integer 0, 1, or 2 as assigned by the caller. 2 = able to deep breathe and cough freely; 1 = dyspnea or limited breathing; 0 = apneic. magent does not auscultate. - `circulation` (integer, required): Circulation (Aldrete 1970). Integer 0, 1, or 2 as assigned by the caller. 2 = BP within 20% of preanesthetic level; 1 = BP 20-50% of preanesthetic; 0 = BP 50% or more from preanesthetic. magent does not measure blood pressure. - `consciousness` (integer, required): Consciousness (Aldrete 1970). Integer 0, 1, or 2 as assigned by the caller. 2 = fully awake; 1 = arousable on calling; 0 = not responding. magent does not examine the patient. - `color` (integer, required): Color (Aldrete 1970). Integer 0, 1, or 2 as assigned by the caller. 2 = pink; 1 = pale, dusky, blotchy, jaundiced, or other; 0 = cyanotic. Not the 1995 SpO2 revision. magent does not observe skin color. ## 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. Method: `POST /api/calc/aldrete` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: 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. Example request: ```json { "items": [ { "activity": "2", "circulation": "2", "color": "2", "consciousness": "2", "respiration": "2" }, { "activity": "2", "circulation": "2", "color": "2", "consciousness": "2", "respiration": "2" } ] } ``` Human paywall (two-item fixture): https://api.magentlab.com/paywall/bulk/aldrete Example 200: ```json { "count": 2, "path": "/api/calc/aldrete", "items": [ { "components": [ { "value": 2, "factor": "activity", "points": 2, "present": true }, { "value": 2, "factor": "respiration", "points": 2, "present": true }, { "value": 2, "factor": "circulation", "points": 2, "present": true }, { "value": 2, "factor": "consciousness", "points": 2, "present": true }, { "value": 2, "factor": "color", "points": 2, "present": true } ], "category": "10", "disclaimer": "Not a medical device.

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. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/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.
