Lung

of the town’s gates. Outside of the village walls, is a simple house made of earth. Here Wang Lung sits in the cold iron cauldron for a bath. In contrast to the village, the countryside is tranquil and quiet. Dried crops crackle in the wind, and Lung hands his father some hot tea. Lung is a simple farmer, so tea is not to be wasted on any normal day, but this is no normal day. This is the day that Lung…

Lung transplantation is a complex surgical procedure that a diseased lung is removed and replaced with a donor lung through anastomosis. In context of transplantation, a patient will receive either a single or bilateral lung transplant from a deceased donor. The current concern for lung transplantation is the shortage of lungs donor. Fortunately, some cases could be relieved by receiving donation from living donors. This procedure involved the removal of one lower lobes of lungs each from two…

Gaseous exchange Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli). Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange.…

Lung cancer carcinogenesis occurs when there is uncontrolled growth of mutated cells in one or both lungs. The cancer develops from mutations in normal cells; the mutated cells form tumors and interfere with the oxygen flow to the body via the blood stream. Tumors develop because of field cancerization, which is the same consecutive genetic and morphologic changes that form an aggressive tumor. Not having oxygen flow can make it very hard for a person to breathe and may cause their body and…

Acute Respiratory Distress Syndrome (ARDS) occur when alveoli of the lungs are filled with fluids due to severe injury or illness. This fluid buildup instead of air in the alveolar air sacs causes decreased level of oxygen transfer from the lungs to the blood stream. A chest x-ray will show clinical appearance of acute pulmonary edema without elevated left atrial pressure or cardiogenic causes (Brochard, 2011). This will cause a severe deprivation of oxygen to vital organs and leads to…

Liquid ventilation (LV) is a form of mechanical ventilation in which the lungs are insufflated with an oxygen-rich liquid, such as perfluorocarbon, rather an oxygen-rich gas mixture (1). There are two primary types of liquid-assisted ventilation: total liquid ventilation and partial liquid ventilation. In total liquid ventilation, the lungs are filled with perfluorocarbon to a volume equivalent to the lung’s functional residual capacity and a liquid ventilator is used to generate tidal breathing…

the lungs. Located on the inner walls of the trachea are small hairs, these hairs catch dust and other contaminants from inhaling, generally through the oral cavity due to its lack of filtration, collected contaminates are later disposed of via coughing. Gas Exchange Lungs: • Bronchi- At the end of the trachea two tubes stem off of its base, each connected to a lung. The bronchi’s connection to the lungs allows air from external respiratory intakes/openings to pass, efficiently, into the lungs.…

researchers' hypothesis was that there was a direct correlation between lung recruitability and positive end-expiratory pressure (PEEP). This would validate the prevailing notion that higher PEEP is only for patients with higher lung recruitability. Previous studies have led to advancements in the field such as the switch from optimal gas exchange to lung protection (Lachmann 1994) and that the optimum PEEP level should avoid lung damage through intratidal opening and closing (Carioni et al.…

deficiency is not a rare disease, but is one that is often underdiagnosed. Normally our lungs are protected by antiproteases because our lungs are exposed to airborne pathogens and hazardous substances. One of these antiproteases is alpha- 1 antitrypsin – which normally is at a high concentration in the lungs.…

the lungs over time. A way to test the progression is a pulmonary function testing (PFT’s). This test, tests the lung capacity of a person ("COPD"). This test is simple and is accurate. It involves a patient blowing out into a tube. The force and duration determines the condition of the lungs. With emphysema it is hard to blow out because air pockets form. To tell what stage a person is in most doctors use the GOLD staging system. GOLD stands for “ Global Institute for Chronic Obstruction Lung…
