Human lung

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.…

Asthma Asthma is a chronic lung disease that irritates and narrows the respiratory airways. This lung disease is not limited to any specific age group, as it affects people of all ages, but it does begin developing in the childhood stage. Around 25 million Americans currently live with asthma, with a third of these people being children.¹ Living with this condition is a responsibility that the affected person must carry. Asthma is not considered to be a life threatening condition by most, but…

A factor contributing to Asthma is an individual’s occupation. The term ‘Occupational asthma’ can be defined when asthma is triggered because of an individual working environment. Typically, there are jobs, which involve being exposed to specific substances known as respiratory sensitizers, which could potentially causes a sickly response. If exposed for a long duration, it could possibly lead from occupational to chronic Asthma. The main examples that could cause occupational asthma is from a…

of the body it is located. An air embolism can also be cause if there has been damage to the lungs. If you are in an explosion the blast may force air into damaged arteries. Although air embolisms are extremely rare they do happen.…

well as damage the lungs. The main focus with irritants is caused by cigarette smoke, air pollution, chemical fumes as well as dust. At times with COPD you may not feel symptoms; there can either be no symptoms or mild symptoms. As the disease gets worse symptoms will then progress, they can then increase and become severe. Some of the symptoms can be cough with mucus, shortness of breath, wheezing, and/or chest tightness. Doctors may request exams and test. A common test is a lung…

Chronic Obstructive Pulmonary Disease (COPD) COPD is a type of lung disease marked by permanent damage to tissues in the lungs, making it hard to breathe. COPD includes chronic bronchitis, bronchi are inflamed and scarred and also emphysema, the alveoli are damaged. It develops over many years and is usually caused by cigarette smoking; pollutants, irritants, dust and chemical fumes can also be a cause. COPD is a progressive disease, which means it gets worse over time. Causing your…

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…

Consistent with its chronicity and its manifestations, asthma impairs a patient’s well-being and can significantly interfere with the ability to undertake normal daily activities, as the disease requires regular complex management. While asthma management plans incorporate a number of recommended health behaviors, the role of medication is vital. People with asthma are likely to be using multiple medications required at different times during the course of the disease; therefore, increasing…

bronchitis. Chronic obstructive pulmonary disease is characterised by abnormal inflammatory obstruction of the airways, lung parenchyma, (respiratory bronchioles and alveoli) and pulmonary blood vessels (Brown, 2013). Research shows that COPD is being recognised as an inflammatory disorder of the large and small airways characterized by remodelling and emphysematous changes in the lung parenchyma (Ceylan, 2006). Thereby this represents characteristic and adaptive immune reaction to long term…

damage the airway and the lining of the lung, which lead to a decrease in lung expansion, which then leads to trouble moving air in and out of the lung causing difficulty with breathing, Irregular breathing, Coughing, discoloration of the skin or nail due to the lack of oxygenated blood. According to case study, Mary had signs of COPD exacerbation which are hash productive cough and SOB, Mary symptoms are caused by the building up of fluid, mucus, and pus in her lung causing tightness of her…
