Frequently Asked Questions
What is the normal range for blood pressure?
Normal blood pressure is 120/80 mmHg. Systolic pressure (top number) should be between 90-120 mmHg, while diastolic pressure (bottom number) should be between 60-80 mmHg for healthy adults.
How accurate is this calculator?
Our calculator uses clinically validated ranges based on American Heart Association and medical guidelines. However, it's not a substitute for professional medical diagnosis or treatment.
Can I save my results?
Yes! You can download your complete analysis as a PDF report, which includes your health score, graphical results, medical advice, and management plan.
Is this tool free to use?
Absolutely! Our Heart & Breath Rhythm Calculator is completely free, requires no registration, and has no usage limits.
When should I seek medical help?
If your blood pressure is consistently above 140/90 mmHg, heart rate above 100 bpm at rest, SpO₂ below 94%, or respiratory rate above 24 breaths/min, consult a healthcare professional.
How often should I check my vital signs?
For healthy individuals, monthly monitoring is sufficient. Those with existing conditions or on medication should monitor more frequently as advised by their doctor.
