What is systolic blood pressure?

Blood pressure is measurement of how much strength blood develops on the walls of blood vessels. There are many different events in the body, because the heart draws blood, known together as a heart cycle, and therefore blood pressure is measured at different points in this cycle. The systolic blood pressure measures the maximum pressure in the arteries during the heart cycle that occurs when the heart contraction or beats to pump blood.

Systolic pressure is measured during routine visitor of the healthcare provider. It is recorded in mmhg or millimeters of mercury. Most medical experts use the ausculation method of blood pressure measurement. Reading is taken with a patient sitting with his arm slightly bent and at the same level as the heart.

The cuff is wrapped around the arm's thumb (2.54 cm) above the elbow and a stethoscope placed on a large brachial artery in the arm. The cuff is inflated to about 30 mmHg higher than the last recorded blood pressure of the patient, when the blood flow is negligible. The cuff is then slowly released and providedEL Health care records the level at which the patient's pulse can first be heard by a stethoscope. This is systolic blood pressure.

When pulse is no longer audible, the second number is recorded: diastolic pressure or the lowest pressure in the arteries that occurs while the heart is at rest between rhythms. These two numbers are recorded as a patient's blood pressure: for example 110/70. Systolic reading of blood pressure is the first number and diastolic pressure second. Some healthcare professionals also use the oscillometric measurement method that is similar but use an electronic pressure sensor to record values ​​instead of a stethoscope.

Blood pressure is influenced by drugs, cardiovascular or urrolemogical disorders, neurological conditions and psychological factors such as stress or anger. Role can also play diet and posture. Because there are so many variables, healthy blood pressure values ​​can drop anywhereeven inside a large range. A healthy adult will have systolic blood pressure between 90 and 135 mmHg. Diastolic pressure ranges from 50 to 90 mmHg.

If the patient's systolic reading is consistently higher than 120 mmHg, he should immediately consult a doctor, especially if the patient is of middle -aged or older. High systolic blood pressure values ​​are the most accurate means to detect hypertension or high blood pressure in adult middle -age and older adults. In many cases, only systolic pressure is high, which is known as isolated systolic hypertension or ISH. Reducing to a healthy level can help prevent congestive heart failure and stroke.
