GENERAL/ALS/MG/NMD/SMA/EPILEPSY/STROKE/DMD: Record the diastolic blood pressure of the participant/ subject. The standard unit for measuring blood pressure is mmHg, which is approximately equivalent to Torr. TBI/TBIACUTE/TBIEPID/TBIMILD/TBIMOD/MS: Record blood pressure from the blood pressure monitor or measure manually by sphygmanometry. The suggested range is 0-300 mmHg. Add date stamp for when assessed.When hourly values are documented, we recommend to take readings at a fixed time point, for example the last minute of the hour. Exclude values which may be influenced by artifacts. Add date stamp for when assessed. The injured brain is often not able to pressure autoregulate normally, adequate perfusion may be more dependent on perfusion pressure; lower blood pressure and low perfusion pressure can aggravate ischemic damage to the injured brain whilst conversely a high blood pressure may lead to increased intracranial pressure and carries an increased risk of neurogenic lung edema. Hypotensive episodes before and after admission adversely affect outcome. In patients with severe traumatic brain injury, routine calculation of the cerebral perfusion pressure on an hourly basis is recommended. 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). SCI: Answer for the past week. Record the patient's blood pressure, height and weight on the scoring form. FA: Record the systolic and diastolic blood pressure (systolic / diastolic) of the participant/ subject. HEADACHE: Measure in mmHg. The preferred position for measuring blood pressure is sitting. Blood pressure is the ratio of systolic to diastolic. It is recommended that standard operating procedures be developed for measuring blood pressure in your study. The Atherosclerosis Risk in Communities (ARIC) and Multi-Ethnic Study of Atherosclerosis (MESA) studies offer examples on their Websites of the procedures they used for measuring blood pressure. Both of these studies measured blood pressure more than once (e.g., three times) at a given study visit.
