1. What is Blood Pressure Calculation?

Definition: This calculator determines the ratio between systolic (SBP) and diastolic (DBP) blood pressure measurements.

Purpose: It helps individuals monitor their blood pressure patterns and understand the relationship between their systolic and diastolic readings.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ BP = \frac{SBP}{DBP} \]

Where:

Explanation: The systolic reading is divided by the diastolic reading to calculate their ratio, which can indicate cardiovascular health patterns.

3. Importance of Blood Pressure Monitoring

Details: Regular blood pressure monitoring helps detect hypertension early, assess cardiovascular risk, and evaluate treatment effectiveness.

4. Using the Calculator

Tips: Enter your systolic and diastolic blood pressure readings in mmHg (typically from a home monitor). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal blood pressure ratio?
A: A healthy ratio is typically around 1.5-1.7 (e.g., 120/80 = 1.5). Higher ratios may indicate increased cardiovascular risk.

Q2: When should I measure my blood pressure?
A: Measure at consistent times daily, preferably in the morning before medications and in the evening before dinner.

Q3: What affects blood pressure readings?
A: Stress, caffeine, exercise, medications, and measurement technique can all influence readings.

Q4: How often should I check my blood pressure?
A: If monitoring hypertension, check 1-2 times daily. Otherwise, periodic checks are sufficient unless recommended otherwise by your doctor.

Q5: When should I consult a doctor?
A: If your systolic is consistently ≥140 or diastolic ≥90, or if you notice significant changes in your ratio over time.
