How this service works
CART integer score from Churpek 2012 Table 3 (beta x 9): maximum respiratory rate, maximum heart rate, minimum diastolic BP, and age, summed to 0-57. magent does not measure vitals; the caller assigns the numbers. Deterministic published arithmetic with citation; not a cardiac-arrest diagnosis and not an RRT order. Does not return risk-band percents.
Output
Returns a single integer CART score (0–57) computed by summing the Churpek 2012 Table 3 point values for each of the four inputs: respiratory rate, heart rate, diastolic BP, and age. No risk-band percentages or diagnostic interpretations are returned.
Example use cases
Ward patient cardiac arrest triage
“A 72-year-old patient on the general ward has a max respiratory rate of 26 breaths/min, max heart rate of 135 bpm, and minimum diastolic BP of 38 mm Hg — what is their CART score?”
Automated EHR early-warning integration
“I'm building an alert system: a 55-year-old patient has peak RR of 21 breaths/min, peak heart rate of 108 bpm, and lowest diastolic BP of 52 mm Hg — calculate their CART score so I can decide whether to escalate.”
Clinical education scoring drill
“For a teaching case, the patient is 48 years old, respiratory rate peaked at 19, heart rate peaked at 105 bpm, and diastolic BP nadir was 60 mm Hg — what CART score does that produce using the Churpek 2012 table?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/cartWhen to prefer
Choose this endpoint when you need a deterministic, published CART integer score per Churpek 2012 Table 3 and the caller already has the four required vital/demographic values. It is ideal for automating ward triage workflows, clinical decision support pipelines, or educational tools where reproducibility and citation traceability matter. Do not use it if you need risk-band probabilities, cardiac arrest diagnosis, or RRT order generation.
Side effects
- Missing required query parameters (respiratory_rate, heart_rate_bpm, diastolic_mm_hg, or age) return a 4xx error
- Values outside valid integer ranges (e.g. age <18 or >120, RR >80) may be rejected or return an error
- Non-integer inputs cause schema validation failure
- Network or payment (x402) errors prevent score retrieval
