Blood Pressure Formula:
From: | To: |
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.
The calculator uses the formula:
Where:
Explanation: The systolic reading is divided by the diastolic reading to calculate their ratio, which can indicate cardiovascular health patterns.
Details: Regular blood pressure monitoring helps detect hypertension early, assess cardiovascular risk, and evaluate treatment effectiveness.
Tips: Enter your systolic and diastolic blood pressure readings in mmHg (typically from a home monitor). Both values must be > 0.
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.
