Lung Compliance and It's Diseases Essays

It results when one or both of these gas-exchanging functions are inadequate . It is not a disease but a symptom of an underlying pathology affecting lung tissue function, 02 delivery, cardiac output, or the baseline metabolic state. It is a condition that occurs because of one or more diseases involving the lungs or other body systems. Symptoms of this is hypoexia and hypercapnia.

1. Explain the change in ERV with exercise. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time. 2. Explain the change in IRV with exercise. IRV decreased as well because the amount of air that was supposed to be inhale was very little inhalation during the time of exercising. 3. Explain the change in IC with exercise. IC increase with exercise beacause the subjects were able to allow their lungs to breath. 4. Explain the change in FRC with exercise. The FRC decrease just a little with exercise. 5. Explain why RV does not change with exercise. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time. 6. Explain why VC does not change with exercise. the vital capacity remain the same because it accumulated the tidal

Lungs – Mucus plugging, chronic bacterial infections, pronounced inflammatory response, damaged airways leading to respiratory insufficiency, progressive decline in pulmonary function.

Once the limits have been reached, there is very little or no change that will occur in the response to any pressure change. This is figured out by using the equation of change in pressure and the change in volume. (Jardins, 2013) By using this equation it will help figure out how compliant the lungs are. This is critical in figuring lung dysfunctions and developing care for a patient. One of the major diseases that lowers the elastance of the lung and the most preventable is Chronic obstructive pulmonary disease (COPD). COPD is categorized with an increase of airway resistance and the loss of lung elasticity. As a restriction in airflow develops, it leads to the hyperinflation of the alveoli. Some other diseases that are caused by low elastic conditions and is related to Hooke’s law are traumatic chest injuries, pneumonia, pneumothorax, pleural effusion, acute respiratory distress syndrome, pulmonary edema, and interstitial lung disease. All of the disease and/or illness’s cause the pressure-volume curve to slide to the right very quickly and allows the lung elastic properties to decrease significantly. (Jardins, 2013)

There are no cure for this disease. However, there are different treatment to prevent further deterioration of the lungs function in order to improve the quality of life of the patient by increasing capacity of their physical activity. One of the main severe complication a patient with COPD can develop is exacerbation. Increased breathlessness, increased sputum volume and purulent sputum are the signs and symptoms of exacerbation. Early detection of the signs of exacerbation can help keep the condition of the patient from worsening. The treatments of COPD mainly aims at controlling the symptoms of exacerbation such as taking inhalers. Patients who are over the age of 35 and ex-smokers with chronic cough and bronchitis are recommended to have spirometer (NICE, 2004). This is because it is possible to delay or prevent patients from developing severe case of COPD is identified before they lose their lungs functions. Oxygen therapy is another treatment for COPD as the patients with this condition has high

The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.

* COPD: Chronic obstructive lung disease decreases the lungs ability to exchange carbon dioxide for oxygen. As the disease progress the patient has to work harder and harder to breathe often feeling as if they are suffocating. These disease are often link to a lifetime of smoking but be due to environmental factors.

This article explains and answer the question of how to keep your lungs healthy and exercise to keep breathing without difficulty and free of lung disease. This means to get regular checkups of your breathing by seeking a physician to listen to your lungs for wheezing. Most lung disease can be prevented with education and less exposure to pollutants in the air. The American Lung Association may aid anyone to stop smoking because overtime cigarette smoking destroys lung tissue and may cause changes that could grow into cancer.

The inflammation of the bronchial tubes makes the nerves in the lungs very senstive. In response to irritation, the body forces air through the airways by rapid strong contraction of the muscles of respiration

The main characterizing feature of Chronic obstructive pulmonary disease is that there is limitation of airflow because the smoke of cigarette directly damages the epithelial cells of the

Emphysema affects the parenchyma of the lung through destruction of the alveolar walls, leading to permanent enlargement of air spaces distal to the

Chronic Obstructive Pulmonary Disease, also known as COPD, is the third leading cause of death in the United States. COPD includes extensive lungs diseases such as emphysema, non-reversible asthma, specific forms of bronchiectasis, and chronic bronchitis. This disease restricts the flow of air in and out of the lungs. Ways in which these limitations may occur include the loss of elasticity in the air sacs and throughout the airways, the destruction of the walls between air sacs, the inflammation or thickening of airway walls, or the overproduction of mucus in airways which can lead to blockage. Throughout this paper I am going to explain the main causes, symptoms, diagnosis, and ways to reduce COPD.

Spirometry is the most popular lung function test. The patient performs a maximal inhalation and then forcefully exhales as quickly and as long as they are able. The spirometer measures the volume of the air exhaled by patients. These measurements are taken at two intervals. The first measurement is the forced expiratory volume in one second (FEV1), records the volume of air exhaled after one second. The second measurement is taken at the point where the patient has fully exhaled the volume of inhaled air; this measurement is the forced vital capacity (FVC) (Harpreet Ranu et al.,

As we breathe in, the muscles in the chest wall force the thoracic area, ribs and connective muscles to contract and expand the chest. The diaphragm is contracted and moves down as the area inside the chest increases as air enters the lungs. The lungs are forced open by this expansion and the pressure inside the lungs becomes enough that it pulls

Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon.
