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 widely accepted in medical guidelines and reflects the healthy range where most adults can function without experiencing significant health risks from high or low blood pressure. The top number, or systolic pressure, represents the pressure in the arteries when the heart beats, and the bottom number, or diastolic pressure, represents the pressure when the heart is at rest between beats.

Blood pressure readings below 90/60 mmHg can indicate hypotension, which may lead to symptoms of dizziness or fainting in some individuals. Conversely, readings above 120/80 mmHg can indicate elevated blood pressure, which may contribute to cardiovascular issues if it persists over time. Maintaining blood pressure within this normal range is essential for overall health and is a primary consideration in emergency medical services and patient assessments.
