In accordance to Mill (2006), Asthma is a chronic obstructive airway disease that often becomes characterized by hyper responsiveness of the trachea-bronchial tree to various stimuli resulting in spasmodic narrowing of air passages (p.1). Another definition of asthma could be that it is an episodic disease clinically manifested by dyspnoea, wheezing and cough. Asthma hence is a respiratory lung disease that is chronic in nature. Asthma always involves two components: in the lungs, constriction causes tightening of air passages, resulting in inflammation, irritation and swelling of airways. Inflammation and constriction of the airways often cause many symptoms. When asthma is left untreated for long, it often results in chronic loss of lung function; in addition it also contributes to a condition called Chronic Obstructive Lung Disease. Once a person gets exposed to a trigger, lungs get inflamed or swollen to an extent that it causes difficulty in breathing (Mills 2006, p.10). 1.2 Historical background of asthma. The term Asthma has originated from the Greek word, which means to pant, or sharp breath or exhale using open mouth. In an epic Greek poem, Iliad, asthma was first mentioned. It became recognized in antiquity with the famous Hippocrates. Hippocrates correlated asthma to metal workers, farmers, tailors, and fishermen among others. With the recognition of asthma caused by external factors like dust and pollen, more studies were carried out to find out the causes and origin of this pathology and its effect on the respiratory system. The first well-documented occupational asthma case was implemented on workers of castor beans in 1923 (Mills 2006, p.3). 1.3 Prevalence of asthma. Asthma affects nearly seventeen million Americans, of which five million are children. Incidence of asthma has increased in the last 15 years by over 50 percent. Nearly five hundred thousand patients become often hospitalised due to asthma. Hence asthma is amongst the top five expensive diseases in the health care system (Mills 2006, p.6). 2. Types of asthma. Asthma can be categorized based on the basis of what triggers it. 2.1 Classification by triggers. 2.1.1 Allergic asthma Allergic asthma becomes often progressively atopic or allergic asthma which is the most common asthma type. It often begins in childhood or early adult life. Patients with allergic asthma have family or personal history of preceding allergic diseases like urticaria, rhinitis or infantile spasm. Patients with allergic asthma often exhibit hyper-responsive reactions to extrinsic allergens. Examples of allergens that affect such people are pollens, house dust, moulds, animal danders and others. Patients with this type often have high levels of IgE levels and test positive for skin test (Mills 2006, p.8). 2.1.2 Seasonal asthma Grass pollen, tree pollen, moulds pollen or flowers release pollen that in turn trigger the asthmatic attack. For instance, some people always find their asthma worse in the spring especially when flowers are flowering compared to other seasons. Others may find their asthma ...

The purpose of this research is to investigate the following: patho-physiology and pathology (mechanisms responsible for causing asthma; symptoms of asthma; types of asthma) and pre-hospital/medical management (diagnosis of asthma; family/medical history of the victim; taking a physical exam; the lung function test; the challenge test; treatment of asthma).
Chronic inflammation with remodelling of the bronchial tree leads to airway obstruction. The disease is more prevalent in young children than adults. Asthma can affect the quality of life and may impact psychologically on the growth and development of a child.
Asthma is a chronic inflammation of airways characterized by continuous and developing inflammatory process that later produces variable clinical presentation such as cough, wheezing etc. Acute inflammation results in broncho-spasm while chronic inflammation affects airway caliber and airflow, thus causing bronchial hyper-responsiveness.
Asthma is known to be a chronic disease, encompassing varied and frequent symptoms resulting in impediment of reversible airflow due to inflammation of inner walls of airways, generating sensitivity to irritations and thereby augments susceptibility to allergies.
In most difficult cases asthma becomes a strong concern for the whole health care area, as it might have fatal outcomes (respiratory failure, suffocation). The disease annually kills more than 5,000 people in the United States, and about 450, 000 Americans need hospital treatment for acute symptoms.
It manifests at almost any age but often starts as early as the childhood years. About 22 million people in the United States, with about 6 million of them being children, are afflicted with this disease. In fact it is the most
