What is the normal range for adult blood pressure?

The normal range for adult blood pressure is considered to be between 90/60 mmHg and 120/80 mmHg. This range is established based on guidelines that define optimal blood pressure levels in healthy adults. Blood pressure readings within this range indicate that the heart is effectively pumping blood with a normal amount of pressure in the arteries, which is essential for good health.

Blood pressure is measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic over diastolic. The systolic number measures the pressure in the arteries when the heart beats, while the diastolic number measures the pressure in the arteries when the heart is at rest between beats. A systolic value below 90 or a diastolic value below 60 typically indicates low blood pressure, while values above 120 for systolic or above 80 for diastolic may indicate elevated blood pressure or hypertension, which can lead to various health issues.

Understanding the normal blood pressure range is crucial for assessing cardiovascular health and recognizing potential medical emergencies related to blood pressure anomalies.
