Behavioral Pain Scale (BPS) Calculator — Payen 2001
x402
Behavioral Pain Scale (BPS) Calculator — Payen 2001 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).
Computes the Payen 2001 Behavioral Pain Scale (BPS) score by summing three caller-supplied integer items (facial expression, upper limbs, ventilator compliance), each rated 1–4, yielding a total of 3–12.

How this service works
Payen 2001 Behavioral Pain Scale from three caller-assigned 1-4 items (facial_expression, upper_limbs, ventilator_compliance) using that paper's Table 1 descriptors. magent sums only (range 3-12) and does not observe the patient. No later pain-present cutoffs. Not a pain diagnosis or analgesic order. Not CPOT (CPOT items are 0-2).
Output
Returns the summed Behavioral Pain Scale total score as an integer between 3 and 12, derived strictly from the three caller-provided subscores using Payen 2001 Table 1 definitions. No pain diagnosis, cutoff interpretation, or analgesic recommendation is included.
Example use cases
ICU pain monitoring during sedation
“My mechanically ventilated patient has a grimacing face (score 4), upper limbs fully bent with finger flexion (score 3), and is fighting the ventilator (score 3) — what is the Behavioral Pain Scale total?”
Routine BPS documentation in nursing workflow
“I need to log the BPS score for a sedated patient: facial expression relaxed (1), upper limbs no movement (1), and tolerating ventilator movement (1). Can you calculate the Payen BPS sum?”
Clinical decision support audit for pain scores
“Double-check my BPS arithmetic: facial expression fully tightened (3), upper limbs partially bent (2), ventilator compliance tolerating movement (1) — what should the total come out to?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/bpsWhen to prefer
Use this endpoint when you need a fast, deterministic arithmetic computation of the Payen 2001 BPS score from pre-assessed subscores and want to avoid manual summation errors in an automated ICU documentation or clinical decision-support pipeline. Prefer this over CPOT calculators (which use 0–2 subscores) or any endpoint that claims to observe or diagnose the patient directly.
Side effects
- Integer values outside 1–4 range for any item will cause a validation error
- Missing any of the three required query parameters returns an error
- Non-integer (float or string) inputs for subscores will be rejected
- Score interpretation (e.g. pain-present cutoff) is not provided — callers must apply their own clinical thresholds
