	MedlinePlus Medical Encyclopedia: Blood pressure
		Blood pressure is a measurement of the force applied to the walls of the arteries as the heart pumps blood through the body.
		The pressure is determined by the force and amount of blood pumped, and the size and flexibility of the arteries.
		Blood pressure is usually measured while you are seated with your arm resting on a table.

	High blood pressure (hypertension) - causes, treatments and medications
		Arteries are vessels that carry blood from the pumping heart to all the tissues and organs of the body.
		Normal blood pressure is below 120/80; blood pressure between 120/80 and 139/89 is called "pre–hypertension", and a blood pressure of 140/90 or above is considered high.
		An elevation of the systolic and/or diastolic blood pressure increases the risk of developing heart (cardiac) disease, kidney (renal) disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke (brain damage).

	High Blood Pressure (Hypertension)
		Blood pressure is the pressure the blood exerts against the blood vessel walls as the heart pumps.
		Blood pressure is driven by two physical forces - the one from the heart as it pumps blood into the arteries and through the circulatory system, and the other from the arteries as they resist this blood flow.
		Blood pressure is measured as air is gradually let out of the cuff, which allows blood to flow through the artery again.

	Blood pressure - Wikipedia, the free encyclopedia
		Blood pressure is the pressure exerted by the blood on the walls of the blood vessels.
		The systolic pressure is defined as the peak pressure in the arteries during the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle).
		Venous pressure is the blood pressure in a vein or in the atria of the heart.

	Hypertension (High Blood Pressure)
		Blood pressure is the pressure your blood exerts against your blood vessel walls as your heart pumps.
		Blood pressure is measured as air is gradually let out of the cuff, which allows blood to begin to flow through the artery again when the blood pressure in the artery is greater than the pressure in the cuff.
		He or she may also perform urine or blood tests to check for other physical problems, such as a kidney problem or a thyroid disorder that sometimes can be the underlying cause of high blood pressure.

	DHDSP - About High Blood Pressure
		High blood pressure or hypertension for adults is defined as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher.
		Prehypertension is defined as a systolic blood pressure of 120–139 mmHg or a diastolic blood pressure of 80–89 mmHg.
		Reduced blood to the heart muscle can lead to angina (chest pain or damage to the heart muscle due to a lack of blood carrying oxygen to the heart muscle) or to a heart attack (caused by a chronic spasm or blockage of blood and oxygen to the heart).

	Blood Pressure
		Pulse pressure is the difference between the systolic and the diastolic readings (the high and low readings) obtained in determining the blood pressure.
		Since high blood pressure seems to have a definite tendency to be inherited, those having high blood pressure in the family should be especially careful on all the points given to prevent the disorder.
		Chilled tissues cause the blood to shunt from the extremities to the interior of the body where vital organs are congested and their function is made less efficient.

	Blood Pressure (Site not responding. Last check: )
		High blood pressure, or hypertension (hi"per-TEN'shun), is defined in an adult as a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher.
		Systolic pressure is the pressure of the blood flow when the heart beats (the pressure when the first sound is heard).
		Blood pressure is measured in millimeters of mercury, which is abbreviated mm Hg.

	Taking a blood pressure
		Blood pressure varies relative to heart's pumping of blood.
		The highest pressures occur during systole as blood is ejected into the aorta and subsequent arteries of the body.
		When you apply a pressure of 180mm Hg to the arm, the 120mm of pressure from the artery cannot overcome your externally applied pressure; the artery stays shut.

	Blood Pressure
		Blood pressure is measured indirectly at the brachial artery of the right arm, however, this may vary at different offices or hospitals.
		Blood pressure measurements which are slightly over 140/90 must be considered stage 1 hypertensive and evaluated again in at least two weeks.
		These individuals whose blood pressure is elevated and it is essential that their blood pressure be elevated (apparently) in order for profusion of blood to get to their kidneys, brain and other body organs.

	Blood pressure
		Note: Blood pressure is measured in millimeters of mercury or andldquo;mm Hg.andrdquo;.
		The higher number is called the systolic pressure and is the pressure exerted on artery walls when the heart is in the contracting phase.
		The lower number is the diastolic pressure and is the pressure exerted on artery walls when the heart is in the resting phase.

	Blood pressure: information about, high blood pressure, symptoms of high blood pressure, risks of high blood pressure
		Blood pressure is the force created by the heart as it pushes blood into the arteries and the circulatory system.
		If high blood pressure is left unchecked, it can cause blood vessels in the kidneys to become thickened and narrowed, possibly leading to reduced blood supply and reduced kidney function.
		It controls the expansion and contraction of blood vessels, and thus blood pressure, by regulating the amount of nitric oxide to which the vessels are exposed.

	Blood pressure
		Blood pressure readings are usually given as 2 numbers: for example, 110 over 70 (written as 110/70).
		The first number is the systolic blood pressure reading, and it represents the maximum pressure exerted when the heart contracts.
		The second number is the diastolic blood pressure reading, and it represents the pressure in the arteries when the heart is at rest.

		As you probably know, high blood pressure is one of he most important cardiovascular risk factor (as diabetes mellitus, dyslipidemia and tobacco) all over the world.
		Many medical studies have shown a relation between obesity and high blood pressure.
		In fact, obese people have a higher blood pressure than people with a normal blood pressure.

		Blood pressure in the pulmonary system is considerably lower than that of the systemic system but there is still a pressure gradient from the blood leaving the right ventricle to the left atrium.
		Pressure difference is the difference between the mean pressure in the aorta and the pressure in the vena cava just before the blood enters the heart (this latter value is almost zero).
		The blood entered the tube and rose upwards (to a height of 2.5 m) towards the tube opening until the weight of the column of blood was equal to the pressure in the circulatory system of the horse.

	High Blood Pressure - hypertension, symptoms, causes, beta blockers, diastolic & systolic
		Your blood pressure is usually measured with a blood pressure cuff placed around the upper arm that registers the pressure in units called millimetres of mercury (or mm Hg).
		Your blood pressure is usually considered to be high when it is at a level exceeding 140/90 mm Hg (“140 over 90”) on several readings under various conditions.
		High blood pressure may be present for several years before it is detected and is often found during a routine check-up, for example, for insurance purposes.

	Heartpoint: High Blood Pressure Information
		The actual mechanisms which explain why the blood pressure is high has to do mainly with the constriction of the small arterioles which are in all of the tissues of the body.
		Blood has to find a way around the obstruction so that there is enough flow for the abdomen, legs, etc. The body is usually successful at providing enough blood around the obstruction, but the pressure is low, including the pressure to the kidneys.
		Blood pressure is generally felt to be abnormally high at a level of 140/90, and some sort of definitive therapy and follow-up should be started at this level.

	Home Blood Pressure Test
		Blood pressure is a measure of the force of blood inside an artery.
		A blood pressure measurement is taken by temporarily stopping the flow of blood in an artery (usually by inflating a cuff around the upper arm) and then listening for the sound of the blood beginning to flow through the artery again as air is released from the cuff.
		These two pressures are expressed in millimeters of mercury (mm Hg) because the original devices that measured blood pressure used a column of mercury.

	High Blood Pressure
		The pressure would cause the garden hose to explode and that is what happens to a blood vessel too small for the pressure going through it.
		High blood pressure also increases the risk of “embolism:” the formation of tiny abnormal blood clots that form when blood flow is normal and can lodge in an assortment of inopportune locations including the brain.
		Blood pressure measurement is performed similarly to the way it is in humans.
