magent Cerebral Perfusion Pressure (CPP) Calculator
x402
magent Cerebral Perfusion Pressure (CPP) Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).
Calculates cerebral perfusion pressure (CPP) from caller-supplied mean arterial pressure (MAP) and intracranial pressure (ICP) using CPP = MAP − ICP, and flags whether CPP meets the Rosner 1995 protocol minimum of 70 mm Hg.

How this service works
Cerebral perfusion pressure from caller-supplied MAP and ICP in mm Hg: CPP = MAP − ICP, rounded to 1 decimal. Returns cpp_ge_70 when CPP is at least 70 mm Hg (Rosner 1995 protocol minimum). magent does not measure MAP or ICP and is not an invasive monitor. Not a medical device and not a treatment protocol.
Output
Returns the calculated CPP value in mm Hg rounded to one decimal place, along with a boolean field cpp_ge_70 indicating whether the CPP is at or above the Rosner 1995 protocol minimum of 70 mm Hg.
Example use cases
TBI monitoring CPP adequacy check
“My TBI patient has a MAP of 95 mm Hg and an ICP of 22 mm Hg — what's the CPP and does it hit the Rosner 1995 target of 70 mm Hg?”
Automated neuro-ICU documentation
“For my neuro-ICU flow sheet, compute CPP from a MAP of 78 mm Hg and an ICP of 14 mm Hg, and flag whether it's at or above 70 mm Hg.”
Elevated ICP scenario evaluation
“If a patient's ICP spikes to 35 mm Hg while MAP stays at 80 mm Hg, what does that do to CPP and does it still meet the 70 mm Hg Rosner threshold?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/cppWhen to prefer
Choose this endpoint when you need a fast, deterministic arithmetic computation of CPP from already-known MAP and ICP values, particularly in automated pipelines, agent workflows, or clinical documentation tools that require the Rosner 1995 threshold flag (cpp_ge_70). It is not appropriate when MAP or ICP values are unknown — this endpoint does not measure or estimate those values.
Side effects
- MAP value outside the accepted range of 30–180 mm Hg returns a validation error
- ICP value outside the accepted range of 0–100 mm Hg returns a validation error
- Missing required query parameters (map_mm_hg or icp_mm_hg) returns a 400-level error
- Non-numeric input for MAP or ICP causes a schema validation failure
- Payment failure (x402) prevents the calculation from being returned
