Blood pressure reading. a unit for measuring pressure). When the two measurements are written down, the systolic pressure is the first or top number, and the diastolic pressure is the second or bottom number (for example, 120 80). If your blood pressure is 120 80, you say that it is "120 over 80." Blood pressure changes during the day. It is lowest as you sleep and rises when you get up. It also can rise when you are excited, nervous, or active. Still, for most of your waking hours, your blood pressure stays pretty much the same when you are sitting or standing still. That level should be lower than 120 80 mmHg. When the level stays high, 140 90 mmHg or higher, you have high blood pressure. With high blood pressure, the heart works harder, your arteries take a beating, and your chances of a stroke, heart attack, and kidney problems are greater. What Is Normal Blood Pressure? A blood pressure reading below 120 80 mmHg is considered normal. In general, lower is better. However, very low blood pressure can sometimes be a cause for concern and should be checked out by a doctor. Doctors classify blood pressures under 140 90 mmHg as either normal or prehypertension. Normal blood pressure is lower than 120 80 mmHg. Prehypertension is blood pressure between 120 and 139 for the top number, or between 80 and 89 for the bottom number. For example, blood pressure readings of 138 82, 128 89, or 130 86 are all in the prehypertension range. If your blood pressure is in the prehypertension range, it is more likely that you will end up with high blood pressure unless you take action to prevent it. What Is High Bl

Ider will close the valve on the rubber inflating bulb and then will squeeze it rapidly to inflate the cuff until the dial or column of mercury reads 30 mmHg (millimeters of mercury) higher than the usual systolic pressure. If the usual systolic pressure is unknown, the cuff is inflated to 210 mmHg. Now the valve is opened slightly, allowing the pressure to fall gradually (2 to 3 mmHg per second). As the pressure falls, the level on the dial or mercury tube at which the pulsing is first heard is recorded. This is the systolic pressure. As the air continues to be let out, the sounds will disappear. The point at which the sound disappears is recorded. This is the diastolic pressure (the lowest amount of pressure in the arteries as the heart rests). The procedure may be performed 2 or more times. How to prepare for the test Return to top The test may be done at any time. When it is performed for comparison purposes, it is usually done after resting for at least 5 minutes. All you need to perform a blood pressure measurement is a cuff and a device for detecting the pulse in the artery (stethoscope or microphone). How the test will feel Return to top You will feel the pressure of the cuff on your arm. If the test is repeated a few times, you may feel temporary numbness or tingling in your hand. Why the test is performed Return to top Most people cannot sense if their blood pressure is high (hypertension) because there are usually no symptoms. High blood pressure increases the risk of heart failure, heart attack, stroke, and kidney failure. For people who have high blood pressure
