The terms "sbp" and "dbp" refer to blood pressure measurements. SBP stands for Systolic Blood Pressure, which is the pressure in the arteries when the heart beats. It is the top number in a blood pressure reading. DBP stands for Diastolic Blood Pressure, which is the pressure in the arteries when the heart is at rest between beats. It is the bottom number in a blood pressure reading. Both SBP and DBP are expressed as natural numbers, typically measured in millimeters of mercury (mmHg).
