Symptoms And Symptoms Of Asthma

Asthma itself is an inflammatory disease characterized by increased airway responsiveness due to a variety of stimulus. The inflammation causes the hyper-responsiveness than in turn causes bronchiolar smooth muscle constriction, resulting in obstruction of airflow. Some

To better understand the impact of asthma, a brief overview of the causes (aetiology) and disease progression (pathophysiology) must be shown. As common as asthma is, not much is known about its aetiology, according to findings presented by Subbaroa, Mandhane and Sears (2009, pg. 181-187) in a review from the Canadian

The effect of asthma can range from mild, irregular symptoms causing minor problems for an individual to severe and sudden asthma attacks. The extent of what causes asthma is not well known or fully understood but some common triggers include, cold temperatures, dust mites, cockroaches, pollen, sickness, mould and animal hair. When triggered, the airways in the lungs become inflamed and constricted causing shortness of breath, chest pain and wheezing [R]. Currently, there is no cure for asthma however symptoms can be managed with medication and improved living standards [R]. Asthma symptoms are commonly controlled with the use of inhalers, either preventers (taken to desensitizes airways to triggers) or relievers (provides instant relief by relaxing the muscles) [16].

According to the American Academy of Allergy Asthma and Immunology (AAAAI), one out of ten children have asthma in the United States (2016). “Asthma is the leading chronic disease in children, it is also the top reason for missed school days.” (AAFA, 2016, para 3). Asthma is described as the inflammation of the bronchi in the lungs. The narrowing of the bronchi makes it difficult to breath, due to the inflammation; a wheezing sound might be heard during an acute asthma attack. Bronchi are small branches in the lungs that helps deliver air or oxygen into the lungs when inhaled, and helps remove carbon dioxide out of the body during expiration. Learning the anatomy of the lungs will be beneficial in learning how asthma affects the body. When a person breaths, the air goes through the nasal cavity, to the pharynx and larynx, then to the trachea and into the lungs, where the bronchi, bronchioles and alveoli are located.

Asthma is a chronic disease of the airways that makes breathing difficult. With asthma, there is inflammation of the air passages that results in a temporary narrowing of the airways that carry oxygen to the lungs. When this inflammation occurs, the asthma symptoms start to show, such as, coughing, wheezing, shortness of breath, and chest tightness. Even though there are many treatments for asthma symptoms, it is still a very serious disease that affects more than 22 million Americans and brings nearly 2 million E.R. visits per year. Asthma can be lived with very well as long as proper treatment measures are taken (Wrongdiagnosis).

Asthma is categorized as a chronic, inflammatory, lower respiratory disease. The term chronic means persist over a long period of time, while the term inflammatory refers to the inflammation within the lung produced by the immune system. The respiratory tract is divided into two sections, upper respiratory and lower respiratory. The lower respiratory includes the trachea and structures within the lungs – the bronchi, bronchioles and alveoli. The inflammation in the air passages causes a temporary narrowing of the airways that carry oxygen to the lungs.

Childhood asthma is a complex chronic inflammatory disorder of the airways that involves both genetic and environmental factors, and can involve potentially permanent airway obstruction, airway hyperresponsiveness, and multicellular inflammation. During an acute episode (which vary in severity and duration), the child presents with symptoms such as wheezing, respiratory distress, cough, chest pain, shortness of breath, and fatigue with exertion (Linzer, 2007). A stimulus (trigger) initiates an airway response that stimulates inflammation, bronchospasm, and increased mucus production. Triggers include cold air, pollen, dust, pet dander, cigarette smoke, exercise, infection, medications,

Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma, the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma is either extrinsic or intrinsic. Extrinsic is when the inflammation in the airway is a result of hypersensitivity reactions associated with allergy (food or pollen). Intrinsic asthma is linked to hyper responsive reactions to other forms of

How is life like diagnosed asthma? How can someone as special as a mother has this disease, and, be able to relentlessly work every day, just to feed her family? My mother is someone who’s impacted by this disease, ever since she was small. But she’s someone who has been through many of the side effects of asthma since she stated in an interview saying, “When I was younger, I lived in the rural areas of Vietnam, specially Danang. At the time medication was very expensive, so I couldn’t afford to buy an inhaler. Which meant I’ve experienced numerous side effects of Asthma. For me, I’ve been through two asthma attacks, both were very serious and did impact largely on my health. It was challenging to live without the medications I needed, but, I fought through it all.” Consequently, there's not really a cure for Asthma now, but there are ways to relieve Asthma.

Asthma is a long term condition that narrows the breathing airways. It can begin in childhood, but can impact people of any age throughout most of their life. It can't be cured, but it can be controlled with supervision from the patient as well as health care professionals. Definition & Facts Airways work like tubes by carrying air in and out of the lungs. People with asthma have inflammed airways that can become restricted.

Currently, physicians will perform a variety of tests to diagnose asthma. Physical exams are done to cross out respiratory infections and COPD. Pulmonary function tests are given to conclude how much air moves in and out of lungs as breathing occurs. Spirometry and Peak flow meters are utilized to perform lung function tests. Patients will need to sit in front of a machine to be fitted with a mouth piece. The mouthpiece needs to fit snug for the reason that all the air that the patient breathes goes into the machine. Patients will also need to wear a nose clip so that air won’t come out through their nose. The physician or RT will instruct the patient to breathe in and out deeply and quickly for several seconds. The

Asthma is a global health concern that is increasing in epidemic proportions. Since 1980, asthma has increased in prevalence by more than 75%, and children appear to be disproportionately affected1. Allergic asthma is an IgE-mediated disorder characterized by airway obstruction and inflammation, infiltration of immune cells (especially eosinophils), airway hyper-responsiveness and mucus overproduction. Common symptoms of allergic asthma include coughing, wheezing, and dypsnea. Allergic asthma has been linked to genetic and environmental factors, and its prevalence is increased in areas of high air pollution. Epidemiological studies have shown increased

The pathophysiology of Asthma includes inflammation of the airway. The way in which this works is from an irritant which can include dust, pollen, cedar, or cat hair. When a reaction occurs, the airways become inflamed and narrow. The narrowing occurs because once the inflammatory response is triggered by an irritant, histamines, immunoglobulin E antibodies, and leukotrienes are released. Because of this, mucous production occurs. Since the bronchioles are inflamed and narrow, breathing becomes difficult. Wheezing sounds can be heard due to the lack of air being able to easily move in and out of the narrowed bronchioles.

Asthma is a common, chronic, respiratory disease that causes the airways of the lungs to swell and narrow. Structurally, the respiratory system consists of two parts. The upper respiratory system includes the nose, pharynx, and associated structures. The pharynx is a muscular tube lined by a mucus membrane that starts at the internal nares and extends to the larynx. The lower respiratory system includes the larynx, trachea, bronchi, and the lungs. The larynx is a passageway connecting the laryngopharynx with the trachea which is an air passageway extending from the larynx to the primary bronchi. It divides into the right primary bronchus and the left primary bronchus, which enter the right and left lung. The lungs are paired organs separated from each other by the mediastinum. Visceral pleura cover each lung and the parietal pleura line the thoracic cavity wall. Within the pleural cavity between the parietal and visceral pleura, pleural fluid reduces friction as the pleura move during breathing. The right lung has three lobes separated by two fissures and the left lung has two lobes separated by one fissure and a depression called the cardiac notch. Both lungs have an oblique fissure which extends inferiorly and anteriorly. It divides the left lung into superior and inferior lobes. The oblique and horizontal fissures divide the right lung into superior, middle, and inferior lobes. Each lobe receives its own secondary (lobar) bronchus. The right primary bronchus gives rise to
