What is the minimum acceptable level for Cerebral Perfusion Pressure (CPP)?

• A. 60 mmHg
• B. 70 mmHg
• C. 80 mmHg
• D. 50 mmHg

Answer: (B)

Cerebral Perfusion Pressure (CPP) is a critical parameter that reflects the blood flow to the brain, which is essential for maintaining normal brain function. The minimum acceptable level for CPP is typically considered to be 70 mmHg. This threshold is important because maintaining CPP above this value helps ensure adequate cerebral blood flow and oxygen delivery to the brain tissue. If CPP falls below this level, there is an increased risk of cerebral ischemia, where brain cells begin to die due to insufficient blood supply. Therefore, setting the minimum acceptable level at 70 mmHg is supported by clinical guidelines and research, emphasizing the need to keep this parameter within safe limits to prevent neurological damage.
