Asthma is a disorder of the lungs that is receiving increasing attention by pulmonary researchers and clinicians as its incidence has risen to epidemic proportions worldwide. Currently, it is estimated that 300 million people are suffering from this chronic disease, which often…
In the US childhood incidence had increases fro 3% to 9% since 1980. Among different ethnic groups in the US, Puerto Ricans have the highest incidence of asthma. African Americans also have a high incidence of this disease. Irish Americans and Hawaiians also have a high incidence of asthma. The lowest incidence is found in the Mexican population. Although the incidence of pediatric asthma is higher in males than in females, the occurrence of this disease is much higher in adult females, who are twice as likely to die of this disease as males. Moreover, the incidence of asthma is higher in lower socioeconomic groups who reside in urban centers.
There are two primary forms of this disease: acute and chronic. The acute form of the disease is characterized by the occurrence of in worsening symptoms and unstable bronchial function. The chronic form of the disease is a stable, non-progressing condition (Adam 10). Many patients with asthma vary over time between the two disease states. Asthma can be distinguished from several other major forms of lung disease by means of differential diagnosis. Unlike emphysema which affects the structure and function of the alveoli, the primary site of gaseous exchange in the lung, asthma affects the airways or conductance passage that transport air between the lung tissue and the external opening of the body. Likewise, COPD is an irreversible deterioration of the primary lung tissue; in contrast at the inflammatory manifestations of asthma are reversible (Adam 20-23).
Asthma is a chronic pulmonary disorder characterized by inflammation of the major airways of the lungs and has a complex etiology. The recurring inflammatory episodes result in hyper-responsiveness of airway vessels that causes tissue swelling with many physiological consequences (Adam 44). These episodes cause symptoms of wheezing, tightness of the chest, coughing and restricted airflow that result in ...

Black Americans have come a long way indeed since the days of slavery and the Civil War which was fought over the issue of slavery. It is also preferred that blacks are called their politically-correct term which is African-Americans.
The airways of an asthma patient swell hence restricting the flow of air in and out of the lungs, thereby making breathing complicated. This disease is also characterized by extreme mucus production, coughing, wheezing, chest tightness and shortness of breath.
This has increased the number of people coming up to get treatment for chronic diseases. According to Falvo (2009), these developments have helped to save the lives of individuals suffering from chronic illnesses. Different from the ancient centuries where the society had negative misconceptions on chronic illnesses, the public has now been sensitized on the positivity of the matter.
In addition, most asthma patients usually complain that the chest feels tight during asthmatic attacks (flare-ups or exacerbations). Asthma attacks may occur infrequently like once or even fewer times a month, or as frequent as a number of times a day (Murphy 5).
It is a common respiratory condition and affects population of all age groups irrespective of race and gender. It constitutes about 2 percent of emergency room visits (Smith and Goldman, 2012). If left unattended and in the presence of severe symptoms asthma can contribute to significant morbidity, mortality and economic costs.
The present research has identified that the pulmonary function tests are significant tools in the diagnosis of asthma. The different investigative modalities available for the diagnosis of asthma have two key fundamentals. These are the history or presence of respiratory symptoms consistent with asthma, and the demonstration of variable expiratory airflow obstruction.
If left unattended and in the presence of severe symptoms asthma can contribute to significant morbidity, mortality and economic costs. Children with acute exacerbation of asthma are frequently seen in out-patient
It constitutes of approximately 2 percent of all emergency department visits (Morris, 2014). The condition is characterized by paroxysmal narrowing of the bronchial airways due to inflammation of the bronchi and also due to
