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)

Worked example

All signs 2

Given: activity=2circulation=2color=2consciousness=2respiration=2

activity 2 + respiration 2 + circulation 2 + consciousness 2 + color 2
Score = 10 (max 10); category 10 (ideal)

Color 0, other signs 2

Given: activity=2circulation=2color=0consciousness=2respiration=2

activity 2 + respiration 2 + circulation 2 + consciousness 2 + color 0
Score = 8; category 8_to_9 (acceptable for recovery-room discharge to the ward)

Score 7

Given: activity=2circulation=2color=0consciousness=1respiration=2

activity 2 + respiration 2 + circulation 2 + consciousness 1 + color 0
Score = 7; category 0_to_7 (continuous close observation)

Parameters

Name	Type	Required	Description
`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.

POST /api/calc/aldrete 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.

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.
