Essential Hypertension

(Marieb and Hoehn, 2010, p 703) defined Blood Pressure (BP) as ‘the force per unit area exerted on a vessel wall by the contained blood, and is expressed in millimetres of mercury (mm Hg)’. BP is still one of the essential and widely used assessment tools in healthcare settings. Nurses generally record the arterial BP which is the forced exerted blood that flows through the arteries, to establish a baseline and to determine any risk factors. BP

Hypertension, also known as high blood pressure, has become a major risk factor for several types of heart disease across the globe. In the United States alone, nearly 70 million adults have been diagnosed with this condition [1]. Hypertension is a condition in which arterial walls experience extreme force from blood flowing through; long-term force against artery walls will lead to more serious health problems such as stroke, renal failure, and other cardiovascular diseases [2]. If the proper steps to treat hypertension are not taken, patients have a high risk of developing atherosclerosis, a condition that causes arteries to harden significantly. Smoking, obesity, lack of physical activity, high alcohol consumption, and high sodium intake are factors that may cause an individual to be diagnosed with hypertension [3] Detection of hypertension is crucial in order to reduce the incidence of death by cardiovascular disease [1].

Hypertension is characterized as an elevation in blood pressure. A blood pressure reading consistently of 140/90 mm Hg or higher is classified as high blood pressure (Appel & Linas, 2012). Hypertension is classified as two forms and they are Essential hypertension and Secondary hypertension. Essential hypertension mainly develops through lifestyle factors such as diets high in salt or low in potassium, lack of exercise, and obesity (Appel & Linas, 2012). Secondary hypertension

As the blood is forced throughout our body, there is a pressure that is exerted on the walls of our arteries, this is known as blood pressure. We see blood pressure represented as two numbers, the systolic (top) and the diastolic (bottom) numbers. The systolic blood pressure is the heart contracting and the diastolic is the heart relaxing. A normal, healthy, blood pressure would be written as 120/80 mmHg (millimeters of mercury) or verbally expressed by most individuals as 120 over 80. Our blood pressure can vary depending on many things. When the diastolic or systolic pressure is high, or significantly and consistently above 120/80 mmHg, this is what we call hypertension. There are different stages or degrees of hypertension. Lippincott Williams and Wilkins (2010) describes the stages as the following:

Hypertension numbers are a trigger of many heart ailments and stroke. But what are hypertension numbers? Blood strain is given as numbers, "x" over "x". The "x" is a number that symbolizes the quantity of mercury within the diagnostic instrument that measures the pressure. The highest reading is a systolic reading and the underside quantity is a diastolic reading. The systolic reading is the stress as the guts beats and the diastolic indicator is the pressure when the guts is at rest. It's these numbers that present the totally different stages of hypertension.

An A-line blood pressure reading is considered more accurate than the cuff pressure reading. During initial assessment, it is routine to compare the A-line blood pressure with the cuff blood pressure. A-line blood pressure readings are higher than the cuff blood pressure readings, and more than a 10% difference may be due to equipment error. Nonivasive blood pressure reading is the most frequently performed clinical parameter and at the same time , not accurately done procedure. Accuracy of the blood pressure reading is vital to the critical care interventions . Clinical situations such as circulatory shock and use of vasopressors, resulting from poor systemic blood flow reduces the intensity of Korotkoff sound. There fore, when you are evaluating cuff blood pressure, make sure that the placement on the arm, cuff size, and techniques are accurate. The cuff bladder circumference should be more than 80% of the arm circumference, and the height of the bladder should be more than 40% of the limb circumference. If the cuff is too small, the BP reading will be high, and a big cuff will give a lower than accurate reading. Remember that the cuff should be 1 inch above the ante cubital fossa and the hand at the heart level. If you need to repeat the reading, wait until the mercury comes to zero, and then wait 1–2 minutes before reinflating again; otherwise, it may produce a

Essential hypertension, otherwise known as primary or idiopathic hypertension, is a condition of raised blood pressure with no identifiable cause. Secondary hypertension occurs when blood pressure elevation results from a specific and potentially treatable cause. These include renal diseases, endocrine causes, congenital cardiovascular causes and pregnancy.

My mother, Nanci, my uncle, Mike, and my aunt Kim have all been diagnosed with hypertension. Hypertension, also known as high blood pressure is the most common cardiovascular disease and leads to over 326,000 deaths in the United States every year (Adams & Urban, 2013). Hypertension is consistent increased systemic arterial blood pressure, and can be divided into two categories, primary and secondary. Primary hypertension has no identifiable cause, and according to Adams and Urban is responsible for almost 90% of all cases of diagnosed hypertension (Adams & Urban, 2013). Secondary hypertension on the other hand is related to an underlying disease process or condition, such as hyperthyroidism or the use of corticosteroids. Hypertension can systemic issue, which means that the blood pressure of the entire body is affected, or it can be a localized issue where only certain tissues are affected, such as the liver. Hypertension is usually an asymptomatic issue, however, when symptoms do appear, they have been caused by the long-term existence of the disorder, over years or decades. Over time, the elevation of the blood pressure begins to wear on the arteries and the organs of

According to research, more than 1 in 3 individuals of the American population have some form of cardiovascular disease. Hypertension is at the forefront for being the most widespread circulatory problem in adults. This condition is distinguished by a person having consistent elevated blood pressure. Although the ranges for healthy blood pressure is different for everyone, medicine tells us that the ideal pressure should remain near 120/80 mmHg. These numbers are a representation of the force being exerted into our arterial system. The first number (Systolic) displays the amount of force upon the arterial walls while the heart beats. Whereas, the second reading (Diastolic) is a measurement of pressure while the heart is relaxed. One notably

THE EFFECT OF PHYSICAL ACTIVITY ON BLOOD PRESSURE Courtney Triplett Bio 211 Lab Mark Fandel March 3rd, 2015 ABSTRACT The purpose of this experiment was to measure the effect one minute of physical activity would have on a subject’s blood pressure. In this experiment, physical activity is defined as stair climbing at a moderate pace. For comparison purposes, standing blood pressure was measured before and after physical activity. One subject was used and three trials were completed and the initial blood pressures were as followed; 94/62 mmHg, 106/74 mmHg, and 102/66 mmHg.

Blood pressure readings are noted in two separate areas, the systolic and diastole. The systole (top number) is the pressure within the arteries when the heart is contracting and pushing the blood forward. When a blood pressure is above the normal range this is notation that the heart is having to work harder to pump the blood properly within the system. The diastole (bottom number) is the pressure within the arteries when the heart is relaxed. A normal blood pressure reading is 120/80, 139/89 is pre hypertensive and 140/90 and higher is labeled as hypertensive. Elevated blood pressures can be divided into two separate categories, this is primary and secondary hypertension (HTN) (Egan & Zhao, 2013).

The most common symptoms are headache, excessive sweating, and increased heart rate. The combination of hypertension with angioma may lead to subarachnoid hemorrhage (i.e. bleeding in the brain).

There are several diagnostic tests that will reveal predisposing factors and identify the cause of hypertension. ECG may show left ventricular hypertrophy or ischemia. A chest X-rat may show cardiomegaly. The funduscopic eye examination will reveal retinal changes such as retinopathy, papilledema, and vasoconstriction. Blood chemistry : elevated sodium, Bun, creatinine, and cholesterol levels, also high blood pressure is diagnose by sustained blood pressure readings greater than 140/90 mm Hg, urinalysis that show protein, red blood cells or shite blood cells that suggest renal

Hypertension is widely considered to be one of the most important risk factors of cardiovascular diseases (angina, arrhythmia, etc.). It is the second leading disease that causes mortality in the world. Hypertension is the condition when there is an increase in the force of blood on the walls of vessels. It can also be defined as an arterial blood pressure that is raised above 140/90 mm Hg (systolic/ diastolic BP). Hypertension can be classified into Secondary hypertension and Essential hypertension. When specific cause is evident but heredity, and various physiological parameters play a role in increasing blood pressure is known as Essential Hypertension. Secondary Hypertension is one where the cause is known. According to WHO guidelines between 2006 and 2015, deaths due to cardiovascular diseases are expected to increase by 17% while the deaths from infectious diseases, nutritional deficiencies, maternal and prenatal conditions are projected to decline by 3%. The main causes of hypertension includes the age ,hereditary, gender, extra weight, alcohol consumption, stress life, lazy life etc.

Hypertension is defined a consistent elevation of the systolic blood pressure above 140mmHg, a diastolic pressure above 90mmHg or a report of taking antihypertensive medication. Early diagnosis and effective management of hypertension is essential because it is a major modifiable risk factor to cerebrovascular, cardiac, vascular, and renal diseases. The higher the blood pressure, the greater the risk for heart attack, heart failure, stroke, and kidney disease.
