What is the normal range for adult blood pressure?

The normal range for adult blood pressure is typically defined as being between 90/60 mmHg and 120/80 mmHg. This range is clinically significant because blood pressure readings within these values indicate adequate blood flow and oxygen delivery to the body's organs while minimizing the risk of cardiovascular complications.

Blood pressure is expressed with two numbers: systolic (the higher number, representing pressure when the heart beats) and diastolic (the lower number, representing pressure when the heart is at rest between beats). The specified range captures the ideal measurements for adults at rest, acknowledging slight variations that can occur based on individual factors such as age, sex, and overall health.

Values outside this range may indicate either hypotension (when blood pressure falls below the normal range) or hypertension (when blood pressure exceeds this upper limit), both of which require medical attention depending on the context and accompanying symptoms.

While the other provided options skew towards lower or limited ranges, they do not accurately reflect the widely accepted normal ranges established by health organizations and research. Understanding the correct normal range is vital for assessing individual health statuses, guiding treatment decisions, and promoting overall cardiovascular health.
