Blood Pressure Analyzer
Enter your systolic and diastolic blood pressure readings to instantly determine your category based on the American Heart Association (AHA) 2017 guidelines. Free, private, and runs entirely in your browser.
Key Capabilities
What do the blood pressure numbers mean?
The top number (systolic) is the pressure in your arteries when your heart beats. The bottom number (diastolic) is the pressure when your heart rests between beats. Both are measured in millimetres of mercury (mmHg).
What are the AHA blood pressure categories?
Normal: below 120/80 mmHg. Elevated: 120–129 systolic with diastolic below 80. Stage 1 Hypertension: 130–139 systolic or 80–89 diastolic. Stage 2 Hypertension: 140+ systolic or 90+ diastolic. Hypertensive Crisis: over 180 systolic or over 120 diastolic — seek emergency care immediately.
When should I seek medical attention?
If your reading is consistently above 130/80 mmHg, consult a doctor. A reading above 180/120 mmHg is a hypertensive crisis — seek emergency medical care immediately even if you have no other symptoms.
Is my BP data private?
Yes. All calculations run locally in your browser. Your blood pressure values are never uploaded to any server.
