Blood pressure is one of the four major vital signs along with heart rate, body temperature, and breathing rate. All these signs can give a major insight into a person’s overall health. Changes or abnormalities in these can suggest an underlying problem and a need to make some lifestyle changes. The typical way to get blood pressure monitored is to visit your general physician who may use a Sphygmomanometer to check your BP. Apart from this, people may also choose to buy a digital or electronic blood pressure checking machine that can be easily used at home to monitor their condition regularly.
