Explanation

Blood pressure readings consist of two numbers expressed as a fraction (e.g., 120/80 mmHg). The upper number represents systolic pressure, which is the pressure in arteries when the heart beats and pumps blood out. The lower number is diastolic pressure, which is the pressure when the heart rests between beats.
