Chronic Obstructive Pulmonary Disease Christopher Lanenga Kendra Tillis Mandy Duea Marna Nersesian Michael Eiden HCS 330 October 4, 2010 Sheela Hirao Chronic Obstructive Pulmonary Disease Although many have heard of the destruction smoking and nicotine can do, much only associate lung cancer with this deadly habit; however, a more common disease can develop. Chronic Obstructive Pulmonary Disease (COPD) is the most frequent form of lung disease, which typically develops after long-term exposure to irritants that damage the lungs and the airways. COPD breaks down into two forms, which are chronic bronchitis, a long-term cough with mucous, and emphysema, defined as a destruction of the lungs over time. In the United States, approximately
The ventilation in older houses causes poor air conditions and makes living conditions hard. The tiny particles of dust are the reason why older buildings have many more dust mites compared to the newer buildings in Springfield. Air quality is a key factor in eliminating being diagnosed with asthma. Dust mites are a problem in Springfield because there are so many older buildings and housing stock that have poor ventilation in them causing an increase of asthma. In order to prevent dust mites vacuuming the rugs, dusting, low humidity in the air and using air fresheners will help keep the air clean.
Because of M.M.’s increased Kussmaul respirations he is unable to fully express carbon dioxide from his lungs causing the carbon dioxide concentration of the blood to increase and the pH to decrease causing acidosis. The physician will likely order a ventilation/perfusion (V/Q) lung scan and a continuous heparin
C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? Alveolar macrophages also known as dust cells remove dust and debris from the alveolar spaces. D. How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? The lung capacity is decreased because the air space is already filled with mucus and fluids therefore she can’t take in enough oxygen. The extra mucus and fluids put extra pressure on the lungs.
Invades nasopharynx where it replicates & spreads down to lower airway via aspiration of upper airway secretions. Causes necrosis of respiratory epithelium of small airways, peribronchiolar mononuclear infiltration & plugging of the lumens with mucus and exudate. The small airways become variably obstructed; this allows adequate inspiratory volume but prevents full expiration. This leads to hyperinflation & atelectasis. Serious alterations in gas exchange occur with arterial hypoxemia & CO2 retention resulting from mismatching of pulmonary ventilation (gas exchange w/in lungs) and perfusion.
High concentrations of sulfur dioxide can result in breathing problems with asthmatic children and adults who are active outdoors. With longer term exposure could include respiratory illness, alterations in the lungs defenses, and aggravation of existing cardiovascular disease. Sulfur dioxide is a precursor of acid rain, which has acidified soils, lakes and streams, accelerated corrosion of buildings and monuments, and reduced visibility which effect the environment. Nitrogen oxide is a group of gases made up of different oxygen and nitrogen. Major sources of nitrogen oxide include fuel combustion in power plants and automobiles and processes used in chemical plants.
B -Environmental Lung Diseases: *Result from inhaled dust or chemicals *Pneumoconiosis is a general term used for a group of lung diseases caused by inhalation and retention of mineral, metal or dust particles *Repeated exposure to the irritant can cause pul. Fibrosis -Chemical pneumonitis *Results from exposure to toxic chemicals *Clinically pt has pul edema -Hypersensitivity pneumonitis *An individual inhales irritants to which they are allergic too *Clinical manifestations occur w/in 4-6 hrs of exposure and incl. fever, chills, cough, SOB and malaise Clinical Manifestations: -Typically do not appear for 10-15 yrs after exposure but incl. dyspnea, coughing, wheezing and weight loss -Cor pulmonale is a late manifestation. *Cor pulmonale is an enlargement of the right ventricle Check what ya know (Answers at end) 6.)
A county that have most fracking is now more polluted than Los Angeles. Doctors also said because of fracking the cancer rate in people is increasing. People can’t be treated because the substances used in fracking are unknown. One the biggest losses are the substances used for fracking are kept unknown from people and even from workers working in these factories. Because they are hazardous.
When this happens, the muscles and tissues that surround the joint weaken. This can deform your joint and make it hard for you to move. Rheumatoid arthritis is an autoimmune disease in which the body's immune system attacks itself. The pattern of joints affected is usually symmetrical, involves the hands and other joints and is worse in the morning. Rheumatoid arthritis is also a systemic disease, involving other body organs, whereas osteoarthritis is limited to the joints.
Pedram Ghodrati Essay Three Writing 122 Air Pollution in Tehran An easy way to define air pollution, anything harmful that goes to the air, makes air pollution. Humans cause 90% of air pollution. The largest contributor to air pollution is the burning of fossil fuels such as gas and coal. The accumulation in the atmosphere of substances can also cause air pollution which, in sufficient concentrations, endanger human health or produce other measured effects on living matter and other materials. Other major factors that make air pollution problem worst include: power and heat generation, the burning of solid wastes, industrial processes, and, especially, transportation.
