name
descriptionThis term is intended as a section header for various blood pressure measurements (e.g., systolic, diastolic). LOINC discourages the reporting of two numbers, such as systolic and diastolic blood pressure (e.g., "120/80"), in one observation. They should be reported as two separate variables, systolic (LOINC 8480-6) and diastolic (LOINC 8462-4).
