|Description:||This image depicts a male clinician in the process of conducting a blood pressure examination upon a seated male patient in a clinical setting. The healthcare provider was using a sphygmomanometer, consisting of a pressurized cuff encircling the patient’s right upper arm, and a monitor indicating changes in pressure within the cuff, as well as a stethoscope in order to listen for, and record the sounds indicative of the high (systolic), and low (diastolic) pressure values used to measure a patient’s blood pressure.|
Measuring your blood pressure is quick and painless. A doctor or health professional wraps an inflatable cuff with a pressure gauge around your arm to squeeze the blood vessels. Then he or she listens to your pulse with a stethoscope while releasing air from the cuff and watching the gauge. The gauge measures blood pressure in millimeters of mercury, which is abbreviated as mmHg.
Blood pressure is measured using two numbers. The first (systolic) number represents the pressure in your blood vessels when your heart beats. The second (diastolic) number represents the pressure in your vessels when your heart rests between beats. If the measurement reads 120 systolic and 80 diastolic, you would say "120 over 80" or write "120/80 mmHg."
