What is the normal blood pressure range for an adult?

The normal blood pressure range for an adult is commonly recognized as 90/60 to 120/80 mmHg. Blood pressure is expressed with two numbers: systolic (the top number) measures the pressure in the arteries when the heart beats, while diastolic (the bottom number) measures the pressure when the heart is resting between beats. Values within this range are considered normal because they indicate that the heart is effectively pumping blood without excessive strain on the arteries.

Maintaining blood pressure within this range is crucial for overall health, as both hypertension (high blood pressure) and hypotension (low blood pressure) can lead to serious health issues. Therefore, identifying the correct normal range helps healthcare professionals monitor patients effectively and address any deviations that may pose a risk to their health.
