Pathophysiology Of Asthma Research Paper

On our honor, we pledge that we have neither given nor received any unauthorized assistance on this case study

The purpose of this paper is to describe the pathophysiology of chronic asthma and acute asthma exacerbation, with explanation of arterial blood gas pattern during an asthma exacerbation. Also, explain how ethnicity might impact pathophysiology of asthma and asthma exacerbation. The diagnosis and treatment plan needed to relieve the presented signs and symptoms will be reviewed. Lastly, constructs two mind maps for chronic asthma and asthma exacerbation including its epidemiology, pathophysiology, clinical presentation, diagnosis and treatment.

1.13. In your own words describe how asthma, which is a chronic illness, can become an acute and life threatening emergency? Asthma is a chronic long term issue where the airways become tightened making it harder to breathe. Acute asthma or exacerbation of asthma is when the airways again become tightened and inflamed, swollen and make it hard to breathe which sounds like wheezing, coughing and difficulty in consuming enough oxygen. Can be caused by a allergenic(Chrisp & Taylor, 2011)

Asthma can be characterized by its high levels of neutrophils which inflame patients’ airways (Tilbury 9). This inflammation

Inflammation of the airways is an important component of asthma. Inflammation can make your airways more sensitive and more narrow than usual, making it harder to breathe. The airways in the lungs may react to various triggers and become more inflamed. The muscles around the airways can also tighten. All these can reduce airflow in your airways and can cause asthma symptoms.

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

A study involving scientists from Cardiff University set out a range of laboratory experiments involving mice models of asthma and samples of human tissue. With the aim of getting a better understanding of asthma patients and what causes the inflammation of the airways. Results show that as a result proteins called eosinophilic cationic protein (ECP) and other important protein. These proteins carry multiple positive electrical charges. This proved that inflammation is caused by these proteins activating another type of protein molecules called calcium sensing receptors found in the smooth muscle cells that line the airways.

Asthma is a disease that has no cure but can be treated and controlled. When the person takes there treatments it controls it better. Treatments

Asthma is a chronic condition. There is no cure for it, but you can work with your doctors and figure out helpful ways to manage it. Inflammation is the cause of the airways closing with certain triggers it causes the airways to tighten and it makes it hard to breathe. It is easier to help asthma if you know the symptoms and triggers. Some symptoms are shortness of breath, coughing, wheezing, and chest tightness. Some of the triggers

Inflamed bronchioles may become over sensitive to allergens or irritants. The airways may become irascible this is called hypersensitive phase of asthma. Asthmatics and allergic individuals have higher risk of bronchial hyperactivity than non-asthmatic and no allergic people. In sensitive individuals, there are 2 times more chances of airways swelling and constriction when they come in contact with triggers such as allergens, cigarette smoke and level of physical activity. In asthma patients, some may have lenient symptoms while other may have critical and drastic symptoms.

Asthma is a major health concern in children under the age of 18. Not only does it have an estimated annual cost of $3.2 million, it accounts for 10 million lost school days, and it disrupts a child’s ability to participate in physical activity. A child with asthma’s exercise performance may decrease from a sedentary lifestyle and the threat of developing an exercise-induced bronchospasm. Granted, keeping asthma patients physically active has proven health benefits and allows for an improved quality of life. The article Benefits of Swim Training for Children and Adolescents with Asthma examines numerous studies that show the benefits of using swimming as a non-pharmacological method for decreasing the severity of a child’s asthma symptoms.

Asthma can best be described as a chronic inflammatory disease involving the pulmonary airways, and bronchial hyper responsiveness that results in lower airway obstruction (Kudo, Ishigatsubo, & Aoki, 2013). The pathophysiology of asthma involves airway inflammation, intermittent airflow obstruction, and bronchial hyper responsiveness (Kudo et al., 2013). It is now considered to be an assortment of several diseases that have similar characteristics and symptoms (London et al., 2017). Cells that were learned to be associated to airway inflammation include mast cells, eosinophils, epithelial cells, macrophages, and activated T lymphocytes (Mims, 2015). These cells influence smooth muscle tone and contribute to remodeling of the airway. Airway hyper responsiveness in asthma occurs from an overactive response to numerous organisms found from

Asthma is a chronic condition that can be managed, but not cured. Asthmatic triggers can be various things for different people. It is often a hypersensitive response to allergens but it can also be triggered by increased anxiety, stress, or even laughter. The bronchi reacts to the stimuli with swelling in the mucous membranes, producing excessive mucous secretions, and causing muscle contraction. Due to the swelling and narrowing of the airways, the result is wheezing and difficulty breathing. The pressure produced doesn't allow for full expiration which means less air is taken in and oxygen levels drop. Asthma is managed through drug prevention with different medications to keep the airways open. Inhalers and nebulizers are used for

The term asthma is derived from the Greek word ἅσθμα (asthma), which means breathing with short, quick breaths.17 Asthma is a common inflammatory disease of the airways.18 It is heterogeneous and multifactorial with variable and mostly reversible airflow obstruction.18 Asthma symptoms include cough, rhonchus, wheeze, chest tightness and shortness of breath.17 The causes of asthma are not completely understood. The strongest risk factors were determined as genetic predisposition and exposure to allergens, tobacco smoke, chemical irritants in the workplace and air pollution.19 To date asthma cannot be cured, avoiding triggers and medications can only control it. Failure to use appropriate medications can lead to

Anderson (2005) states that asthma is one of the major and most common chronic inflammatory disorder that damages or changes the structure of the airways, causing problem in the respiration process due to excess secretion of mucus, and hyperactivity of the cells of the airway. In 2012, the World Health
