Understanding Hypertension: Blood Pressure

 

Hypertension/High Blood Pressure

When the doctor said, “Your blood pressure is 135 to 85″, for example, the figures really mean?

The first number is the systolic blood pressure (SBP) – the amount of pressure in the arteries of the heart as a pump. Systole is the rhythmic contractions of the heart muscle, where the expulsion of blood from the left ventricle – a large room on the left side of your heart. Aortic valve, located between the camera and your aorta, the large artery that takes blood from the heart to the rest of the body. During systole, the aortic valve is open and blood flowing freely for the rest of the body.

The second number is the diastolic blood pressure (DBF). After your heart blood flow from the ventricle, the aortic valve closes to prevent returns blood to the heart of the rest of your body. Your heart muscle contracts and expands the ventricle, the blood, it fills the left atrium, which he came out of the lungs. In the arteries, blood pressure drops, until it reaches its low point. Diastolic blood pressure – the second issue, which is read by the sensor or on top of the mercury column reflects the lowest point in blood pressure. Before it falls back to other contracts of the ventricle, and blood pressure begins to rise back up the level of systolic pressure.

Once you’ve established your garden, and DBF, the definition of blood pressure is high and should be treated. But first, how high is too high?

At birth, your blood pressure is about 90/60 mm Hg or even lower. As you get older, it gradually increases until the adult blood pressure, usually between 120/80 mm Hg and 139/89 mm Hg higher than that and you believed that high blood pressure.

No fixed number serves as a guide for the systolic and diastolic blood pressure, which tells you your blood pressure is high, if it is higher or lower number, if it is below the number. Doctors established 140/90 mm Hg, the point at which action is taken, but the fact remains that people with blood pressure 120/80 mm Hg lower risk of complications with blood pressure than people with 130 / 85 mm Hg

National Heart, Lung, and Blood Institute, a division of the National Institutes of Health, created the Joint National Committee on Prevention, Detection, Evaluation and treatment of hypertension. The committee established the classification of blood pressure in adults, as shown in Table 2-1. Use the chart to determine the extent of blood pressure normal or abnormal. If blood pressure falls in the high normal or high blood pressure categories, discuss treatment with your doctor.  Note: The SBP and DBP fall into different categories, use the higher category. In addition, mercury is the chemical notation of mercury.
Classification of blood pressure for adults

Category ——– SBP (mm Hg diastolic )———- (mm Hg)

Optimal ——— <120 —– ——- and <80

———- Normal <130 —– ——- and <85

High normal 130-139 or 85-89 — ——– —-

RAP Stage 1 140-159 or 90-99 — — ——–

Stage 2 RAP — — 160 to 179 or 100-109 ——–

Stage 3 RAP — —— ——– 180 + or 110 +
