This blood pressure calculator categorizes systolic and diastolic readings according to widely used ACC/AHA thresholds. It helps interpret a single blood pressure reading and also reports pulse pressure and mean arterial pressure (MAP), two supporting hemodynamic markers often used in cardiovascular and critical care contexts.
Formula: Classification uses ACC/AHA thresholds; MAP = DBP + (SBP - DBP)/3; Pulse Pressure = SBP - DBP
Your category reflects where your entered reading falls in guideline-based blood pressure ranges. Elevated and hypertensive categories indicate progressively higher long-term cardiovascular risk, especially when readings are consistently high across multiple measurements.
MAP and pulse pressure provide additional context. MAP helps estimate average perfusion pressure, while pulse pressure can reflect arterial stiffness. These supporting values are not substitutes for diagnosis but can guide follow-up and risk discussions.
Use this tool when reviewing home blood pressure logs, clinic readings, or screening results. It is useful for quickly translating raw numbers into a category that supports next-step decisions.
It can also support preventive counseling by linking blood pressure readings to broader cardiovascular risk tools such as ASCVD Risk and Framingham Risk.
A single reading does not diagnose chronic hypertension. Proper cuff size, seated rest before measurement, repeated readings, and longitudinal trend review are essential for accurate diagnosis.
This calculator does not incorporate age, comorbidities, medications, or end-organ symptoms. Very high readings with concerning symptoms require urgent in-person evaluation rather than online categorization.
