What is indicated by a blood pressure reading of 120/80?

A blood pressure reading of 120/80 mmHg is considered normal based on established guidelines from health organizations such as the American Heart Association. This reading falls within the optimal range, which indicates that the heart is working effectively without excessive strain on the arteries.

The first number, systolic pressure, measures the pressure in the arteries when the heart beats, while the second number, diastolic pressure, measures the pressure in the arteries when the heart rests between beats. A systolic reading of 120 is within the normal range (less than 130), and a diastolic reading of 80 is also within the normal range (less than 80). Therefore, this combination reflects a healthy cardiovascular function.

Other interpretations of blood pressure readings, such as high blood pressure, pre-hypertension, or low blood pressure, would apply to different numerical ranges, none of which include this specific reading. Hence, a reading of 120/80 is correctly identified as normal blood pressure.
