Asthma
Asthma is a disease of the airways of the lungs, which is characterized by increased sensitivity of the airways to a variety of triggers. It is generally an episodic disease, i.e., acute attacks followed by symptoms free periods. Though most attacks are generally short lived, sometimes-serious conditions occur in which severe Asthma is unrelieved for many hours or even days. Asthma occurs in all age groups, but is found to be more common in children. It tends to affect both sexes equally. If a person has Asthma, their trachea and bronchial tubes become more sensitive. It is when they are more irritated does the muscles and the lining constrict more easily. There are two types of Asthma, Allergic and Idiosyncratic. Allergic Asthma is often associated with personal or family history of other types of allergic diseases like hay fever, rhinitis, and eczema. The offending agents causing asthma include environment and air pollution, certain drugs like aspirin, occupational factors such as working with animal skins, and chemicals, infections of the chest or upper respiratory tract can bring about an acute attack of asthma and even exercise and emotional stress. The most characteristic features of Asthma are breath
Albuterol is an inhaled bronchodilator that relaxes the muscles in the respiratory tract and dilates the airways to improve breathing. Specific allergy induced attacks are relieved with anti-allergic medication usually administered by injection to desensitize the asthmatic to the allergen. The use of Inhalers and Nebulizers are the most common treatment for asthma. Another example of the affects of having an Asthma attack is feeling as if someone has thrown a blanket over your head and you are unable to uncover your self. If one has allergies and also has Asthma they may be subjected to frequent Asthma attacks. Today, in the United States and Australia, an estimated five percent of adults and ten percent of children suffer from the condition. They are known as B cells and T cells. Moderate to severe attacks can be relieved by a combination of bronchodilators and anti-inflammatory drugs targeted at reducing constriction and inflammation of the airways. Used extensively in hospitals, nebulizers are particularly effective for the treatment of infants, children and adult patients. Nebulizers have one big advantage over ordinary inhalers: they can deliver the drugs to the airways and control an asthma attack, even when movement of breath in and out of the lungs is severely reduced. Acute attacks a combination of bronchodilators, intravenous adrenalin and theophylline; the use of inhaled steroids is preferred. The albuterol might be mixed with cromolyn to prevent the onset of another attack.
