Blood pressure occurs due to our heartbeat that makes the blood circulate in blood vessels. Our heart acts as a pump making the blood flow under pressure. Circulating through arteries, blood takes oxygen and nutrients to our organs and tissues. It is evident that blood pressure is among our vital functions. Blood pressure has maximum and minimum levels and varies depending on person. At present, much attention is paid to making people understand the importance of keeping their blood pressure under control as its abnormal levels are often associated with numerous health problems including kidney and heart disorders.
Blood pressure readings are offered as two numbers, for example 120/80. The first of them is the systolic pressure (maximum), the second refers to diastolic readings with relaxed cardiac, or heart muscle (minimum). When analyzing the state of the patient, the physician always takes into consideration both figures. In case of elevated systolic pressure as with 150/90 readings high blood pressure or hypertension may be diagnosed.
