describe high blood pressure. Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Blood pressure readings are usually given as two numbers -- for example‚ 120 over 80 (written as 120/80 mmHg). One or both of these numbers can be too high. The top number is called the systolic blood pressure‚ which is the force of blood in the arteries as the heart beats‚ and the bottom number is called the diastolic blood pressure which is the

All these combined measurement can give us an insight into the patient’s health or Physiological state. 2.1 The heart is simple a pump which forces the blood around our bodies through the pipe work we call our arteries and veins. We can measure this force on our vascular system by measuring our blood pressure. Blood pressure is measured in millimeters of mercury (mmHg)

63-YEAR OLD MAN WITH HYPERTENSION You have been diagnosed with hypertension‚ which is commonly known as high blood pressure. Blood pressure is the force of blood pushing against the blood vessel walls. So with high blood pressure the arteries have constant raised blood pressure. Every time your heart beats it pumps blood to the whole body through the arteries. The higher your blood pressure is the harder your heart has to pump. Hypertension may be caused by many things but some examples are smoking

disorder characterized by a sustained elevation of systolic arterial pressure of 120 mm Hg or higher‚ or a diastolic arterial pressure of 80 mm Hg or greater or higher‚ or both. Hypertension is divided into two categories: essential hypertension and secondary hypertension. Research has shown that hypernatremia increases the volume of blood‚ which raises blood pressure. Primary hypertension may also develop from alterations in other bosy

friend Jemima‚ the other patients have all experienced a drop in blood pressure (Hypotension) and have an elevated heart rate (125-135 bpm) Hypertension occurs when blood pressure drops below 90 mm Hg systolic or 60 mm Hg diastolic number.

Peripheral Arterial Disease Peripheral Arterial Disease April 22‚ 2010 ME 1352 Abstract Peripheral Arterial Disease is a common secondary disease that follows Atherosclerosis. Once so much plaque builds up in the arteries‚ they become block the blood flow. P.A.D. usually affects the lower extremities and can cause intermittent claudication and‚ if severe enough‚ gangrene. Many people live with atherosclerosis and P.A.D. and show no symptoms. There are numerous prevention methods for P.A.D that

fancy word for high blood pressure. Blood pressure is the amount of pressure that your blood is putting on the walls of your arteries. Now most people don’t even realize they have high blood pressure because more often than not‚ there are no signs or symptoms going along with it. Now‚ when checking your blood pressure we put on the blood pressure cuff and then we listen for your heart beat. There are two stages we get‚ one is as we release the pressure of the cuff‚ at a certain pressure we will hear
