Cerebral perfusion pressure CPP = MAP - ICP (MAP measured or derived from SBP/DBP); BTF target band ~60-70 mmHg.

Example
- MAP
- 90 mmHg
- ICP
- 20 mmHg
Result: CPP 70 mmHg (60-70 mmHg recommended Brain Trauma Foundation target band).

Carney N, et al. Guidelines for the Management of Severe Traumatic Brain Injury, 4th Edition. Neurosurgery. 2017;80(1):6-15. CPP = MAP - ICP; recommended target band 60-70 mmHg; aggressive maintenance above 70 mmHg with fluids/pressors is discouraged (respiratory-failure risk). Read the source ↗
