How this service works
Mean arterial pressure from cuff systolic and diastolic BP using diastolic + pulse pressure / 3. Conventional 1/3 estimate, not an invasive aortic mean. Deterministic published arithmetic with citation; not a treatment target.
Output
Returns a numerically computed mean arterial pressure value in mm Hg, derived using the Diastolic + (Pulse Pressure / 3) formula. The result is a deterministic arithmetic calculation based on the conventional 1/3 estimate from noninvasive cuff measurements, with a citation to the published methodology. It is not an invasive aortic mean and should not be interpreted as a treatment target.
Example use cases
ICU hemodynamic assessment
“Can you calculate the MAP for a patient in the ICU with a cuff BP reading of 95 systolic and 60 diastolic? We need it for the chart.”
Hypertension management check
“My patient has a blood pressure of 155 over 95 — what's their mean arterial pressure using the standard 1/3 pulse pressure formula?”
Pre-op anesthesia screening
“Before surgery, a patient's BP was recorded as 132 systolic and 82 diastolic. Can you calculate their MAP for the anesthesiologist?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/mapWhen to prefer
Use this endpoint when you need a quick, deterministic, citable MAP estimate from standard noninvasive cuff blood pressure readings. Prefer it for clinical documentation, decision-support workflows, or automated chart calculations where the conventional 1/3 pulse pressure formula (Diastolic + PP/3) is the accepted standard. Do not use if an invasive aortic mean or arterial-line-derived MAP is required.
Side effects
- Missing systolic_mm_hg or diastolic_mm_hg parameters returns validation error
- Diastolic value greater than or equal to systolic value triggers invalid input error
- Values outside accepted ranges (systolic 50-250, diastolic 20-160) may be rejected
- Non-numeric input types cause schema validation failure
