Blood pressure checker
See where a reading falls on the American Heart Association scale.

AHA scale: Normal <120/80 · Elevated 120–129/<80 · High stage 1 130–139/80–89 · High stage 2 140–179/90–119 · Crisis >180/>120
One reading isn't the full story
Blood pressure naturally shifts through the day with stress, caffeine, posture, and activity. Clinicians typically want several readings, taken at rest and on different days, before drawing conclusions — especially before any diagnosis.
This tool is informational only. A crisis-range reading (>180/>120) with symptoms like chest pain or shortness of breath needs immediate medical attention.
