Asthma is an obstructive airway disease where airway resistance is increased and inflammation is present. This inflammation and obstruction (narrowing of the airways) result in an increased resistance of expiratory airflow, and expiration is not passive, but need aid from expiratory muscles.…
Most people with asthma only have symptoms when they inhale a ‘trigger’ such as pollen, exercise without the right preparation, or catch a cold or flu.…
Asthma is a chronic condition of the respiratory system that causes hypersensitivity and reversible inflammation of the airways resulting in breathing difficulties (Levy et al., 2006).…
Despite of the advances in medical therapy, millions of Americans continue to suffer from asthma; a respiratory disorder defined, by chronic inflammation airways and characterized by presence of persistent cough, shortness of breath, and wheezing that commonly occurs after exposure to a stimulus. The severity, of this respiratory ailment varies from patient to patient, and its classification( mild, moderate, severe persistent asthma) is based on the patient's signs and symptoms manifestation as well as the frequency and/or exacerbation events experienced by the patient. Consequently, once a diagnosis has been established, data obtained from the patient's history and diagnostic evaluation is crucial to guide the medical therapy(Woo, & Robinson, 2016).…
Asthma is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Common symptoms include wheezing, coughing, chest tightness, and shortness of breath. Asthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms, response to therapy over time. In severe cases hospitalization can be required.…
Asthma is a chronic disease of the lungs and one of the most common long term diseases in children ("Asthma ", n.d). The actual cause of asthma is unknown and there is currently no cure, but certain things in the environment trigger the inflammation of the airways, ultimately leading to asthma attacks. However, it is manageable and can be prevented by avoiding your triggers. Triggers vary for every person, but the most common are tobacco smoke, dust mites, pets, and pollution ("Asthma ", n.d). The symptoms include tightness in the chest, coughing, and wheezing ("Asthma ", n.d). Asthma attacks can be deadly if they are not taken care of right away. During an attack the airways in your lungs shrink and do not allow enough air to pass through.…
The 3 main features of asthma include airway obstruction, inflammation, and airway irritability. Normal breathing for the human body includes air moving freely to and from the lungs but, with asthma the bands of muscle around the airways tighten causing the airway to not be able to go through freely. In other words, the lungs do not get enough air and this causes the human to feel a shortness of breath or to have trouble breathing—this is known as airway obstruction.…
Asthma is just a general term for what is going on, there are three types of asthma. Each asthma name base off of what triggers the asthma attack. The three types of asthma are allergic asthma, mixed asthma and idiopathic asthma. Allergic asthma occur due to an irritants such as allergens trigger the asthma attack. This occurs due to the fact that the allergens aren’t recognized by our body’s immune system. Since it is unrecognizable it causes the white blood cells in our body to recognize it as a threat. This then promotes our helper T cells to activate the production of B cells which then causes antibiotics to be made. The production of the B cells signals the thymus to make more lymphocytes. The allergens have often just settled within our airway. The production of more white blood cells (specifically immunoglobulin E cells) causes the area to become inflamed. The inflammation of the airway causes the bronchioles to contract (get tighter) which leads to the patient to have trouble with breathing. Allergens such as pet dander, pollens, spores and dust mites are usually responsible for setting off an allergic asthma attack. The second type of asthma is idiopathic asthma. The reason why this is called idiopathic asthma is due to the fact that the exact reason why it is triggered during specific events is unknown. Idiopathic asthma is usually triggered by respiratory infection, exercises and emotional upsets. These thing can lead to an asthma attack due to the fact that they can cause the bronchioles to…
Asthma is a common long term condition that can cause cough, wheezing and breathlessness. These are severity of the symptoms which can vary from person to person, and asthma can be controlled well in most people most of the time. Asthma is caused by inflammation of the airways, these are small tubes called bronchi which would carry oxygen in and out of the lung, as the individual bronchi would inflame and become more sensitive than normal, when the individual comes into contact with something that irritates his lungs (trigger off) his airways become narrow and the muscles around the lungs tighten which makes…
With asthma, there is inflammation of the air passages that results in a temporary narrowing of the airways that carry oxygen to the lungs. This results in asthma symptoms, including coughing, wheezing, shortness of breath, and chest tightness.Asthma triggers are different from person to person and can include: Airborne substances (such as pollen, dust mites, mold spores, pet dander or particles of cockroach waste), respiratory infections (such as the common cold), physical activity (exercise-induced asthma), cold air, air pollutants and irritants (such as…
Asthma is a lung disease that can be treated. It is a chronic inflammatory disease of the respiratory system that results in relapsing symptoms. In simpler terms, asthma is the narrowing of the airways in the lungs that causes wheezing, coughing, and gasping for breath. It is a very unpredictable disease and can differ greatly from one person to the next. Some people have very mild symptoms every once and a while where as for others it is a daily struggle to breath. Asthma can occur at any age but most commonly begins with in the first five years of life. Approximately 7% of Americans suffer from asthma, which is roughly 18 million people, 4.8 million of which are children. Asthma is the leading cause for hospitalization among children and is the most common long-term childhood disease. “African-Americans are four times as likely as whites to be hospitalized and three times as likely to die from asthma.” This is partially because asthma is more sever in urban inner cities. Although many cases of asthma have been identified in the United States, many cases are likely to go undiagnosed.…
Asthma often runs in families. Half of the cases in the United States are due to genetics and half result from environmental factors. Outdoor allergens, such as pollens from grass, trees and weeds Indoor allergens, such as pet dander, dust mites and mold might trigger asthma. Also, irritants in the air, such as smoke, chemical fumes and strong odors may lead to a tightness in the chest. One way that triggers my asthma is colds, the flu or other illnesses. Many experience asthma when, exercising. However, people with asthma can benefit from some exercise. Stress is also a major factor. Others include, weather conditions, such as cold air or extremely dry, wet or windy weather and physical display of strong emotion that affects normal breathing patterns, such as shouting, crying or…
The Pathophysiology of asthma is complex and involve airway inflammation with intermittent airflow obstruction and bronchial hyperresponsiveness. Asthma is the attack of the Paroxysmal dyspnea where airway inflammation and wheezing occur due to contraction to the of the bronchioles. To begin with, this chronic disease is a common pulmonary condition which manifest with an inflammation of the respiratory tube that develops episodes of bronchoconstriction. According to Cramer (2011), “The redness and inflammation of the airways is similar when the skin become red and irritated after a sunburn” (p. 503). Additionally, asthma has “triggers” that makes the airways become swollen and the space for air to move in and out the lungs become narrow. The muscle turns tighter and make breathing even harder as a…
Asthma is a chronic inflammation of the lung airways. The number of Americans with asthma grows every year; now 26 million Americans is experiencing asthma. Asthma results in a number of emergency room and outpatient visits annually. Asthma is the most common illness in childhood, counting for 10.5 million missed school days each year. Living with asthma is an everyday struggle. Many symptoms of asthma include wheezing when breathing out, persistent cough especially at night. People with asthma also experience difficulty in breathing, shortness of breath and heaviness in the chest (Simon 2013). Although patients can control asthma with medication, it is still a growing concern as 1 in 11 children and 1 in 12 adults has asthma. Asthma is a serious…
Most people who have asthma are sensitive to a variety of triggers. A person’s asthma changes depending on the environment activities, management practices and other factor.…
