Outline the major diseases of the respiratory system with reference to the pathophysiology.

Respiratory or lung diseases are the most rapidly diseases expanding worldwide. Health problems of the lungs or airways make it very difficult to breath. They could be lasting a short amount of time like the common cold or for years. Other allergic diseases, which affect the respiratory system. Respiratory diseases are mostly caused by indoor pollutants. The primary function of the respiratory system is to supply the blood with oxygen. When this fails death is not excluded. Lung diseases occur within the lungs. Some lung and respiratory diseases include asthma, pneumonia tuberculosis and lung cancer. Those will be analyzed in the following essay. [1]
Asthma or reactive airway disease is a chronic disorder that results in restricted breathing due to inflammation of the bronchi tubes the main air passages in the lungs. Asthma affects 3-5 % of adults and 7 -10 % of children in the USA. Sever asthma attacks can cause approximately 5000 deaths per year. Three changes occur in the lungs of the people with asthma. First inflammation or swelling where the airway becomes inflamed and produce a mucous. Inflammation then leads to constriction of the muscles around the airways causing the airways to become narrow. This narrowing is also referred to as bronchiole spasm. The third change is increased sensitivity of the airways causing the asthma patient to become overly sensitive to animal dander, pollen, cold air and tobacco smoke to name a few. Patients have to work with their doctors for the correct medication to control symptoms and minimize attacks.[2]
Regular pneumonia is an infection of the lungs where the lung tissue is filled with fluid or pus. Symptoms include rapid breathing, fever, chills, chest and abdominal pain, presence of brown, yellow or green colored mucous or cough.

...PAPER 1 Cardiovascular Paper: R.G.’s Risk Factors for Cardiovascular Disease CARDIOVASCULAR PAPER 2 Cardiovascular Paper: R.G’s Risk Factors for Cardiovascular Disease In almost every year since 1900, cardiovascular disease has been the number one cause of death in the United States. Nearly 2300 Americans die of CVD each day, and average of one death every 38 seconds. This disease kills more people than the next four causes of death combined, including cancer, chronic lower respiratory diseases, accidents and diabetes. Of particular concern is that CVD is the leading cause of death for women (Ignatavicius and Workman, 2013). Risk Factors Gender According to, Huether and McCance (2012) more women in the United States die from coronary artery disease and stroke than from all cancers combined. Women have a higher rate of CAD related mortality than men, in part because of under diagnosis and treatment. Menopause is associated with increased exposure to risk factors and poor endothelial healing. Endogenous estrogen is said to be protective of vascular function and when this is reduced after menopause hits the risk of CAD increases. Postmenopausal women are two to three times more likely than premenopausal woman to have CAD. Diabetes Diabetes mellitus is an extremely important risk factor for CAD. Insulin resistance and diabetes have multiple effects on the cardiovascular system including endothelial damage, thickening of the vessel wall, increased inflammation...

Abg Case Study

...Provide and interpretation of Derek’s ABGs. Derek’s blood gases are as follows PaO2 80mm/Hg PaCO2 52mm/Hg PH 7.25 HCO3 30 The results show that Derek has respiratory acidosis. According to Porth and Matfin, (2009) respiratory acidosis is a condition was an acid imbalance occurs in the body. During gas exchange, the exchange of gas is impaired and results in excess carbon dioxide (CO2) being absorbed into the blood stream, initiating the formation of an acid, making the blood more acidic (Porth & Matfin, 2009). The PH drops as there is little ventilation of the alveolar, and compensation results in the production of hydro carbon dioxide (HCO2) (Farrell & Dempsey 2005). Respiratory acidosis may be caused by injury to the respiratory centres, diseases of the lungs, blockage of the airway and respiratory disorders (Porth & Matfin, 2009). b.) Provide two possible reasons for the ABG’s based on Derek’s history and presentation. The cause for Respiratory acidosis in Derek could have been caused by a respiratory disorder such as COPD which he has been diagnosed with since 1997, and was asked to cease smoking but up to date he has continued to smoke 20-30 cigarettes per day. Porth and Matfin, (2009) explain that conditions of the respiratory system may cause impairment of gas exchange. Respiratory acidosis could also have been caused by poor diet intake. Derek has hypercholesterolemia and type 2 diabetes mellitus, he lives close to convenience stores and often...

Heart Failure

...Failure Christy Harding Western Governors University C155- Pathopharmacological Foundations for Advance Nursing Practice Heart failure affects nearly 6 million Americans. It is the leading cause of hospitalization in people older than 65. Roughly 550,000 people are diagnosed with heart failure each year (Emory Healthcare, 2014). Heart failure is a pathologic state where the heart cannot pump enough blood to meet the demand of the body’s metabolic needs or when the ventricle’s ability to fill is impaired. It is not a disease, but rather a complex clinical syndrome. The symptoms of heart failure come from pulmonary vascular congestion and inadequate perfusion of the systemic circulation. Individuals experience orthopnea, fatigue, dyspnea, cough with frothy sputum, peripheral edema, and decreased urinary output. Heart failure is caused by many conditions that damage the heart’s muscle. Any form of heart disease can lead to heart failure. A1. Pathophysiology Heart failure arises as a consequence of an abnormality in cardiac structure, conduction, rhythm, or function (Figueroa & Peters, 2006). Heart failure always begins with an index event. This event could be silent, as with the expression of a genetic mutation, or obvious, such as a myocardial infarction (Francis & Tang, 2003). Heart failure can be categorized into systolic ventricular dysfunction also known as systolic heart failure or diastolic ventricular dysfunction also known as diastolic heart failure. Each...

Heart Failure

...Heart Failure It is estimated that about five million people in the United States are living with heart failure with an overwhelming number of 550,000 newly diagnosed cases each year, costing the nation roughly $32 billion dollars per year (Centers for Disease Control and Prevention, 2016). Heart failure is a complex, pathophysiological condition in which the ventricles of the heart is weakened and unable to pump effectively to meet the body’s needs for nutrients or has lost adequate filling capacity. Clinical presentations of heart failure depends on which ventricles have failed to pump blood adequately; left ventricular failure, also known as congestive heart failure (CHF) is more common than right ventricular failure (McCance & Huether, 2014). The most common symptoms of heart failure are shortness of breath, fatigue, and peripheral edema. HF is not a disease, but rather a manifestation of a diseased heart. Large number of disorders can lead to heart failure, and with the aging population and many surviving primary cardiac events, it is no surprise that the most common reason for hospitalization in patients older than 65 years old is heart failure (McClintock, Mose, & Smith, 2014). Heart failure has become a major public health problem because it is the only cardiac condition that continues to increase in prevalence (McClintock, Mose, & Smith, 2014). Organizations such as American Heart Association (AHA), National Heart, Lung, and Blood Institute (NHLBI),...

...ork2012 - 2013 Catalog A Message from the President “Sullivan University is truly a unique and student success focused institution.” I have shared that statement with numerous groups and it simply summarizes my basic philosophy of what Sullivan is all about. When I say that Sullivan is “student success focused,” I feel as President that I owe a definition of this statement to all who are considering Sullivan University. First, Sullivan is unique among institutions of higher education with its innovative, career-first curriculum. You can earn a career diploma or certificate in a year or less and then accept employment while still being able to complete your associate, bachelor’s, master’s or doctoral degree by attending during the day, evenings, weekends, or online. Business and industry do not expand or hire new employees only in May or June each year. Yet most institutions of higher education operate on a nine-month school year with almost everyone graduating in May. We remained focused on your success and education, and continue to offer our students the opportunity to begin classes or to graduate four times a year with our flexible, year-round full-time schedule of classes. If you really want to attend a school where your needs (your real needs) come first, consider Sullivan University. I believe we can help you exceed your expectations. Since words cannot fully describe the atmosphere at Sullivan University, please accept my personal invitation to visit and experience...
