x402
Campbell RDOS Calculator (Respiratory Distress Observation Scale) 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 Campbell 2010 Respiratory Distress Observation Scale (RDOS) score (0–16) for patients unable to self-report dyspnea by summing eight caller-assigned 0–2 integer subscores.

How this service works
Campbell 2010 RDOS for patients unable to self-report dyspnea. Eight caller-assigned 0-2 integers (heart_rate, respiratory_rate, restlessness, paradoxical_breathing, accessory_muscle_use, grunting, nasal_flaring, look_of_fear). magent sums only (max 16); does not convert raw heart or respiratory rate or observe the patient. Campbell 2010 published the 0-16 instrument; magent does not apply later cutoff papers. Not a medical device and not an opioid or oxygen order.
Output
Returns a single integer RDOS total score between 0 and 16, which is the arithmetic sum of the eight caller-assigned subscores. Does not interpret the score against cutoff thresholds from later publications, does not convert raw physiological measurements into subscores, and does not produce clinical recommendations or medication orders.
Example use cases
Palliative care dyspnea screening
“I'm assessing a non-verbal palliative care patient — please compute their RDOS score: heart rate 2, respiratory rate 2, restlessness 1, paradoxical breathing 1, accessory muscle use 1, grunting 0, nasal flaring 0, look of fear 1.”
ICU non-communicative patient distress score
“My ICU patient can't self-report breathing difficulty. Can you calculate the Campbell RDOS total with these observer-assigned points: heart rate 1, respiratory rate 2, restlessness 2, paradoxical breathing 0, accessory muscle use 2, grunting 1, nasal flaring 0, look of fear 0?”
End-of-life respiratory distress documentation
“I need to document an RDOS score for a sedated end-of-life patient. The subscores are: heart rate 0, respiratory rate 1, restlessness 0, paradoxical breathing 2, accessory muscle use 1, grunting 2, nasal flaring 2, look of fear 0. What's the total?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rdosWhen to prefer
Use this endpoint when you need to programmatically compute a Campbell 2010 RDOS total score from eight pre-assigned observer subscores for a non-verbal patient. It is the right choice when a clinician or care system has already mapped observations to the 0–2 Campbell scale points and simply needs the arithmetic sum validated and returned. Do not use it to convert raw heart rate or respiratory rate values into subscores — that binning must be done by the caller before submission.
Side effects
- Missing required subscore parameter returns a 400-level error
- Non-integer or out-of-range values (outside 0–2) for any subscore cause a validation error
- Payment failure (x402) if USDC payment is not provided or insufficient
- Server error (5xx) if the API is unavailable
