The tools to measure blood pressure are a sphygmomanometer (blood pressure cuff), stethoscope or a digital blood pressure monitor. The sphymomanometer and the stethoscope are used together to get a blood pressure reading. The digital blood pressure monitor is used by itself.
Start Taking Blood Pressure
The cuff of the sphygmomanometer has a spot that is placed over the site of the brachial artery on either arm. The stethoscope is placed under the edge of the cuff over the artery. The medical worker pumps the cuff, squeezing the arm.
The Blood Pressure Final Reading
The first sound heard after steadily deflating the cuff is the systolic number, or the top number on the blood pressure fraction. The last sound heard from the steadily deflating cuff is the diastolic number, or the bottom number on the blood pressure fraction.
Normal Adult Range
A normal blood pressure reading for and adult is between 90 to 130 for the systole and 60 to 80 for diastole.
Too High or Too Low
Anything above 140/90 is cause for concern and must be brought to a doctor's attention. Anything below 90/60 might have a person feeling faint and should also be looked at by a doctor.
Exercise Blood Pressure
During exercise, the systole can increase to between 195 to 220, but the diastole can decrease to 75.
