The nurse is caring for a child with a closed head injury. The child's blood pressure is 120/58 mmHg, and intracranial pressure is 16 mmHg. What is this child's cerebral perfusion pressure? (Enter numeric value only. Calculate to the nearing hundredth decimal point.)

Cerebral perfusion pressure is calculated by subtracting the mean intracranial pressure from the mean arterial pressure or MAP - ICP = CPP. To calculate mean arterial pressure, the nurse should subtract the diastolic blood pressure from the systolic blood pressure and divide the result by 3 and then add that sum to 80. For this patient, the MAP would be calculated as being (120 - 58) / 3 + 80 = 100.67. To calculate the cerebral perfusion pressure, take the value of the mean arterial pressure and subtract the child's intracranial pressure or 100.67 - 16 = 84.67. The child's cerebral perfusion pressure is 84.67.
