Blood pressure screening bell curve

This bell curve is a teaching illustration of aggregated systolic blood-pressure readings from a workplace screening. It shows how a continuous measurement can cluster around a center with fewer observations at the extremes. It is not a diagnostic chart and cannot determine what any individual's reading means. Clinical interpretation depends on repeated measurements, context and professional guidance. In an education or aggregate-reporting setting, the chart can help explain distribution, variation and why a group average does not describe every person. Keep individual readings private and use approved health processes for follow-up. It gives teams a concrete starting point for reviewing assumptions, data quality and next steps together.
