Two numbers, different pressures
A blood pressure reading reports pressure when the heart contracts and when it relaxes. Interpretation depends on the actual values, how the measurement was taken, medical history and applicable clinical guidance.
Measurement conditions matter
Rest quietly before a reading, use a correctly sized cuff and follow the device instructions. Repeated measurements taken appropriately often provide more useful information than a single reading made during stress or activity.
Discuss results with a clinician
Do not diagnose yourself from one reading or adjust medication without guidance. Very high readings accompanied by symptoms such as chest pain, severe shortness of breath or neurological changes require urgent medical assessment.
A thoughtful next step
Use this guide as a starting point, not a rigid rulebook. Consider your own circumstances, look for reliable sources, and seek qualified professional advice when a decision affects your health or safety.
