Respiratory disease

The Respiratory System’s Vital Role in the Human Body Lakessia Dumas Dominque Johnson Lashonda Johnson Jessica Mager Keyaira Studvent Dorsey School Of Nursing Abstract The human lungs are amazing feats of nature; they help us pump vital oxygen through airways and into the bloodstream every second of the day. Without this ability, humans could not survive on Earth. This paper explores the major parts of the respiratory system, the main purpose and how it plays a crucial role in the human…

restrictive lung diseases such as pulmonary fibrosis and obstructive lung diseases such as asthma. Secondly, I would do a maximal voluntary ventilation test (MVV). This measures the greatest quantity of air that can be breathed in and breathed out in one minute. The exam is commonly carried out greater than 15 seconds, which will require you to breathe in and out as vigorously as possible (Ranu et al., 2011). This exam can be beneficial in evaluating the overall capacity of the respiratory…

abnormal inflammatory response in the lungs that affects gas exchange. “This is caused by loss of elastic recoil and airflow obstruction caused by mucosal hypersecretion, mucosal edema, and bronchospasm”. One of the two Chronic Obstructive Pulmonary Disease (COPD) is chronic bronchitis. It is caused when the bronchi and bronchioles become inflamed by exposure to smoke or environmental irritants. Thick mucus production begins due to the inflammatory process, which causes airway obstruction and…

1.Introduction COPD is the common chronic disease with the high rate of morbidity and mortality. It is estimated that COPD will become the third leading cause of death in 2020.1 The most noticeable symptoms of this disease are productive cough, shortness of breath and limited exercise capacity. While the main obvious pathophysiological hallmark of COPD is Expiratory Flow limitation which causes acute dynamic lung hyperinflation, dyspnea is increasingly implicated as the primary symptom causes…

The respiratory system is the major system of organs that facilitates the process of respiration. This system controls a gas exchange which involves the distribution of oxygen throughout the body and the removal of carbon dioxide from the body as waste. In other words, it plays a crucial role along with the circulatory system during the action of breathing and maintains a constant supply of oxygen into the bloodstream. In turn, the respiratory system provides trillions of cells with energy from…

organs in the body. When complications with infections occur regions of the lung can fill with fluid, also babies born premature can have underdeveloped lungs causing increased surface tension. These cause the lungs to remain closed, a disease called respiratory distress syndrome. The deformation of biological cells when exposed to different flow conditions is a problem. Surface tension on an air–liquid boundary creates liquid flows, which causes the lung to close due to the formation of a…

Asthma is a disorder that effects the upper respiratory system, mainly the lungs. The airways to the lungs become inflamed which cause narrowing of the airways. When the airways become narrow or obstructed the air is not able to pass into and out of the lungs. This is what causes the breathing issues associated with asthma. When discussing asthma, one must consider triggers such as allergens or irritants. The triggers to asthma symptoms vary among people. The irritants include but are not…

Cystic fibrosis is a disease that has no cure and affects approximately 30,000 children in the United States. The life expectancy of patients with cystic fibrosis has increased over the past 50 years dramatically. Advancements in medications and therapies have allowed patients a longer and more productive life. Genetic research, pharmaceutical technology, and therapy advancements have been the forefront in increasing patient age. The drug Ivacaftor is helping some patients by treating the…

lowers a person’s level of confidence, and cause emotional distress. You will often get frustrated when afflicted by tiny white bumps on lips as most of the time you may imagine the people around could be thinking you have a sexually transmitted disease. However, small white bumps on lips have various causes, some which are serious health issues while are others are simply non-issues at all. The spots we are talking of here, don’t have any specific location for appearance as thy can surface on…

on the patient’s condition. Anyone who have problem in breathing normally, or having chronic diseases may require mechanical ventilator. It also includes patients suffering from spinal cord injury, stroke or any other disorders. Rapid growth in geriatric population, changing lifestyles, increase in the cases of preterm birth, growing pollution levels & urbanisation, and high prevalence of chronic diseases are some of the key driving factors for the growth of the Global Mechanical Ventilator…
