| C01578 | Cerebral perfusion pressure value | CerebrlPerfusPressrVal | Value of the difference between the Mean Arterial Pressure (MAP) and the Intracranial Pressure (ICP). It represents the pressure gradient driving cerebral blood flow and hence oxygen and metabolite delivery | Value of the difference between the Mean Arterial Pressure (MAP) and the Intracranial Pressure (ICP). It represents the pressure gradient driving cerebral blood flow and hence oxygen and metabolite deliver | Cerebral perfusion pressure value (mmHg) | Numeric Values |
Calculate Cerebral Perfusion Pressure using the formula CPP = MABP- ICP. In the ICU environment, recording blood pressure on an hourly basis is recommended, especially when intracranial pressure (ICP) is monitored in order to permit determination of CPP, calculated as mean arterial blood pressure (MABP) - ICP (supplemental data set). |

The suggested range is -10 to 300 mmHg. Recommend collection during acute hospital care. Add date stamp for when assessed. It is recommended to document the highest ICP, zeroing the ICP monitor at the level of the foramen of Monro and to relate all hourly data to date and time of injury, as being the only fixed time event across patients. Monitoring for and treating raised ICP is an important element in the management of patients with severe TBI. Pediatric-specific notes: As a minimum, vital signs should be recorded on admission and further, on a daily basis during the acute phase after injury. For the Core datasets, we recommend recording the average and lowest blood pressure over a given period. In the ICU environment, recording blood pressure on an hourly basis is recommended, especially when intracranial pressure (ICP) is monitored in order to permit determination of CPP, calculated as mean arterial blood pressure (MABP) - ICP (intermediate data set). For valid comparison of results between patients and across studies, a common approach towards zeroing the ICP monitor should be agreed upon. For fluid coupled systems we suggest that the ICP monitor be zeroed to the level of the foramen of Monro. |

The average does not need to be the mathematical average of multiple measurements, but rather the value most representative of this 'daily' period. It is recommended to zero the ICP monitor at the level of the foramen of Monro and to relate all hourly data to date and time of injury, as being the only fixed time event across patients. Monitoring for and treating raised ICP is an important element in the management of patients with severe TBI. |
