Question

Calculate the CPP for the pt with an ICP of 34 mmHg and a systemic BP 108/64 mmHg.

Option 1: CPP = 34 mmHg
Option 2: CPP = 20 mmHg
Option 3: CPP = 40 mmHg
Option 4: CPP = 70 mmHg

Answer 1

To calculate the cerebral perfusion pressure (CPP), subtract the intracranial pressure (ICP) from the systemic blood pressure. In this case, the ICP is 34 mmHg and the systemic blood pressure is 108/64 mmHg. The calculated CPP is 43.33 mmHg.

Step-by-step explanation:

To calculate the cerebral perfusion pressure (CPP), you need to subtract the intracranial pressure (ICP) from the systemic blood pressure. CPP = Systemic blood pressure - ICP. In this case, the ICP is given as 34 mmHg and the systemic blood pressure is given as 108/64 mmHg. To calculate the CPP, subtract the ICP (34 mmHg) from the mean arterial blood pressure (MAP), which is calculated as (systolic BP + 2 * diastolic BP) / 3. So, the CPP would be (108 + 2 * 64) / 3 - 34 = 232 / 3 - 34 = 77.33 - 34 = 43.33 mmHg.
