Blood Pressure By: Lauren Faircloth Patient: Shana Richardson February 16, 2014 BIO 211 CJ1 February 19, 2014 Introduction Blood pressure is pressure excreted by the blood upon the walls of the blood vessels. Arteries are usually measured on the radial artery by means of a sphygmomanometer and expressed in milliliters of mercury as a fraction having a numerator as the maximum pressure that follows the systole of the heart and a denominator as the minimum pressure that accompanies cardiac diastole (Definition â Systemic Blood Pressure by Human Physiology. (n.d.). Retrieved from http://news.rapgenius.com/1653425/Human-physiology-systemic-blood-pressure/1-definition). A normal blood pressure reading for an adult is one hundred and twenty over eighty. To take a blood pressure, a blood pressure cuff and stethoscope, or an automatic device is needed. The instruments measure blood pressure by auscultation of korotoff’s sound, or either record korotkoff sound by microphone to take the measurements using oscillometric principle of analyzing pressure pulses in the cuff. Systolic pressure is the numerator, which is also the higher of the two numbers, measures the pressure within the arteries when the heart beats. The diastolic pressure is the denominator of the fraction, which is the lower number of the two; it measures the pressure within the arteries between heartbeats. In 1773 Hales first measured blood pressure by sticking tubes in the arteries of animals. Blood pressure measurement was first used in 1901 under anesthesia by Cushing, now it is a standard of patient monitoring. Taking blood pressure is important because the higher t... ... middle of paper ... ...ity. High blood pressure is a major problem in America. Children in America are now more likely to be obese due to fast food, and high sodium content found in common household foods. An experiment should be done to show the effects high blood pressure has on children. Awareness of which foods cause high blood pressure and exercise will help promote a healthier lifestyle. High blood pressure is the silent killer. People often over look the severity of high blood pressures short term and long effects. Often many years pass without symptoms of high blood pressure which increases the chances for heart attack and stroke. Aristotle first noted the health benefits of daily exercise. A study provided evidence that burning 1,000 to 2,000 calories per week reduces risk of death. Exercise should be performed at least three to five times a week for an active prolonged life.
How does this history of high blood pressure demonstrate the problem description and etiology components of the P.E.R.I.E. process? What different types of studies were used to establish etiology or contributory cause?
The individual will have their blood pressure levels taken using a blood pressure machine called a sphygmomanometer, where a cuff is placed around the individual’s arm and fills up with air to create pressure around the arm to restrict the amount of blood flow and takes a pulse reading as it releases the pressure. After the individual’s blood pressure has been taken they may be asked to take it at home using a blood pressure kit to see if it is still high and that the first reading was not due to anxiety.
The Mayo Clinic’s book on High Blood Pressure was full of detailed facts about blood pressure and what it is. This is extremely significant to the experiment because blood pressure is one of the variables being tested. Understanding blood pressure is one of the key components to receiving accurate results from this experiment. Most of the book is on high blood pressure, which is not necessary for the experiment, but the book still had plenty of useful information about blood pressure itself. The book explains that when the heart beats, a surge of blood is released from the left ventricle. It also tells of how arteries are blood vessels that move nutrients and oxygenated blood from the heart to the body’s tissues. The aorta, or the largest artery in the heart, is connected to the left ventricle and is the main place for blood to leave the heart as the aorta branches off into many different smaller
High Blood Pressure is anything that alters in peripheral vascular resistance, heart rate, or stroke volume that affects systematic arterial blood pressure. Long term effect of high blood pressure are serious and can cause heart attacks, strokes, kidney failure, and retinal damage. Hypertension is another medical word that substitutes the meaning of high blood pressure. It is known as the “silent killer” because it does not create any symptoms. The most common reason for high blood pressure is arteriosclerosis. Arteriosclerosis is the thickening and hardening of the walls of the arteries, occurring in old age. Four control systems have a job in maintaining blood pressure. These are the arterial baroreceptor and chemoreceptors’ system, regulation of body fluid volume, the renin- angiotensin system, and vascular autoregulation. Primary hypertension mostly occurs from a defect or malfunction in some or all of these
High blood pressure is called the “silent killer” because it often has no warning signs or symptoms, and many people don’t know they have it. For most patients, high blood pressure is found when they visit their health care provider or have it checked elsewhere. Because there are no symptoms, people can develop heart disease and kidney problems without knowing they have high blood pressure. Some people may experience: bad headache, mild dizziness, and blurry vision. Traditionally, diagnosis of high blood pressure (BP) has relied on consecutive checks of clinic BP over a 2 to 3 month period, with hypertension confirmed if BP remains persistently raised over 140/90 mmHg. This method of diagnosis has significant limitations because the BP measured for an individual patient in a clinic setting may not reflect their BP in day-to-day life. The main concern is that as a result of the “white coat syndrome”, hypertension may be over-diagnosed when checked in the clinic setting; resulting ...
Systolic blood pressure is 120/80 the diastolic blood pressure within normal range. Any blood pressure above 139/89 is pre-hypertension. Stage one hypertension is between 140-159 or 90-99, Stage two 160-179 or 100-109 diastolic and Stage three 180 above diastolic110. (Lewis, S.M, Heitkemper M.M &Dirksen, S.R 2004) pg 779.
Hypertension is diagnosed by measuring the blood pressure by a device known as the sphygmomanometer. Blood pressure is taken and presented by the systolic blood pressure and diastolic blood pressure. The systolic and diastolic numbers will be recorded and compared to a chart of values. At the same time, doctor would also ask for patient’s family history of hypertension and the associated risk factors such as high cholesterol food intake.
Your blood pressure reading is expressed with two numbers — for example, 120/80. The first number, known as systolic blood pressure, is a measurement of the force your blood exerts on blood vessel walls as your heart pumps. The second number, known as diastolic blood pressure, is a measurement of the force that blood exerts on blood vessel walls when the heart is at rest between beats.
In order to impede the epidemic of childhood obesity, the actual causes of the problem need to be evaluated and dissected. Obesity in children is becoming a huge problem in American society. In the past three decades, the rate of overweight children has increased by 300%. This is an alarming rate that is only climbing higher. Every member in society should take steps to becoming healthier. This would help the present generations as well as future generations to come. The lifestyle of Americans keeps us too busy to be a healthy society.
Throughout history, it seems that medicine and spirituality have been linked in many circumstances. In a study looking at the use of complementary and alternative therapies in cardiac patients, spiritual healing was one of many practices patient sought to utilize. In another study, 29% of participants chose to use prayer or premeditation as a way to cope with their chronic illness. In both studies, prayer or meditation was more likely to be used by individuals who had a large social network, as well as support from another person in the same health situation. Based on these studies, it seems that many individuals (not just cardiovascular patients) turn to their spirituality in times of health distress.
Blood pressure is measured by two pressures; the systolic and diastolic. The systolic pressure, the top number, is the pressure in the arteries when the heart contracts. The diastolic pressure, the bottom number, measures the pressure between heartbeats. A normal blood pressure is when the systolic pressure is less than 120mmHg and Diastolic pressure is less than 80mmHg. Hypertension is diagnosed when the systolic pressure is greater than 140mmHg and the diastolic pressure is greater than 90mmHg. The physician may also ask about medical history, family history, life style habits, and medication use that could also contribute to hypertension
Exercise is often thought of in a positive light. It is common belief in today’s society that a healthy diet and a regular exercise routine will lead to a long, healthy life. And in the simplest sense of the word, it will.
Staying healthy does not only mean to eat a healthy diet, but also to be active and to provide our body with stamina so it can fight various diseases. According to Myers (2003) around a quarter of a million deaths in the United States are caused by insufficient physical activity. The US Public Health Service (1996) has provided enough evidence towards the effect of physical exercise on cardiovascular (e.g. coronary heart disease) and non-cardiovascular health (hypertension, osteoporosis, colon cancer etc.). They followed a group of people for several years and found a positive correlation between the amount of participants’ physical activity and their health problems. So how much exercise is just enou...
Blood Pressure: Blood Pressure is the force at which blood pushes against the blood vessels. The blood pressure of women can be below, normal or above normal. When the level is below or above normal, 120/80, it poses a number of health risks. Women between ages 18- 65 years and above require a blood pressure test every two years if blood pressure is 120/80. Any blood pressure between 120/80 and 139/89 will require your medical doctor to require blood pressure test once a year. Above this level, the doctor will request for
Exercise will help to control your weight. It will also reduce the risk of cancer and diabetes. Experts recommends children and teens to get at least an hour of exercise everyday. Adults should exercise for two hours and thirty minutes weekly. Exercise does not only mean, go to the gym and work out on treadmills and such. Taking your dog for a walk, gardening, and everyday chores are considered exercise too. Daily exercise can relieve some stress because it can stimulate brain chemicals leaving you to feel more relaxed and happy. It can also boost up your self esteem and confidence because if you’re working out, your appearance would most likely improve. Another great reason for exercising is that it will boost your energy, and you will have more energy because of all the muscle you built up.
