Cerebral Perfusion Pressure Calculator
Calculate CPP to assess brain oxygen supply and perfusion adequacy
Calculate Cerebral Perfusion Pressure
Normal CPP ranges vary by age group
Normal MAP: 70-100 mmHg (adults), 50-90 mmHg (children)
Normal ICP: 7-15 mmHg (adults), 2-10 mmHg (children)
Cerebral Perfusion Pressure Results
Formula: CPP = MAP - ICP
Calculation: 0.0 - 0 = 0.0 mmHg
Clinical Interpretation
Example Calculation
Adult Patient Example
Patient: 45-year-old adult with traumatic brain injury
Mean Arterial Pressure (MAP): 85 mmHg
Intracranial Pressure (ICP): 10 mmHg
Age Group: Adult (18+ years)
Calculation
CPP = MAP - ICP
CPP = 85 - 10
CPP = 75 mmHg
✅ Normal CPP for adult (60-80 mmHg range)

Understanding Cerebral Perfusion Pressure
What is Cerebral Perfusion Pressure?
Cerebral Perfusion Pressure (CPP) is the net pressure needed to maintain adequate blood flow to the brain. It represents the driving pressure for cerebral blood flow and is critical for ensuring the brain receives sufficient oxygen and nutrients.
Why is CPP Important?
- •Ensures adequate brain oxygenation
- •Prevents brain ischemia and cell death
- •Monitors neurological status
- •Guides treatment decisions
CPP Formula
CPP = MAP - ICP
- CPP: Cerebral Perfusion Pressure (mmHg)
- MAP: Mean Arterial Pressure (mmHg)
- ICP: Intracranial Pressure (mmHg)
Critical Values: CPP <40 mmHg indicates severe brain ischemia risk
Clinical Conditions Requiring CPP Monitoring
Acute Conditions
- • Traumatic brain injury (TBI)
- • Stroke and cerebral hemorrhage
- • Brain herniation
- • Intracranial hypertension
Surgical & ICU Care
- • Neurosurgical procedures
- • Brain tumor resection
- • ICU neurological monitoring
- • Hemodynamic instability
