Explain The Pathophysiology 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

Asthma is a long-term lung disease. Those with asthma have sensitive airways in their lungs which triggers a flare up. When this flare up happens the muscle around the airways squeeze tight and the airways swell, become narrows and produce more mucus. (Anon., 2016) All these things make it harder for a person to breathe. Asthma effects the human body’s respiratory system. Asthma causes a spasm and constriction of the bronchial passages and the swelling and the inflammation of the mucous lining. The body responds by defence cells from the immune system, which causes the airways to swell and the muscles surrounding the airways to contract. Which is what cuts off the airflow. While a person is in asthma attack, the asthmatic cannot breathe which

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.

Describe the early signs of an acute asthma attack and relate each of these to the changes taking place in the lungs.

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).

Throughout the years knowledge about asthma has grown, as well as treating it effectively. Over 300 million people are said to be victims of this disease with another 100 million being estimated by 2025 globally (Currie and Baker, 2012). In the United Kingdom, asthma is increasingly becoming one of the leading disease affecting individual of different age, ethnicity, race and gender. British Lung Foundation (2011) stated that it is more common at childhood stage and can also occur at a later age. According to Asthma UK (2014) asthma in men is less prevalence than it is in women and children troubled more with asthma than adults. Recent data in the UK shows that in children and occupational asthma in adult is on the rise with an estimate

Asthma affects people of all ages, but it most often starts during childhood. Asthma is a chronic lung disease that inflames and narrows the airways, which are tubes that carry air into and out of your lungs allowing one to take in oxygen and breathe out carbon dioxide. The swelling also can worsen, making the airways even narrower and the ability to breathe more difficult. Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine, but other times symptoms continue to get worse. When symptoms get more intense and more symptoms occur, you 're having what is commonly known as an asthma attack. During an asthma attack you are in complete panic and the swelling in your airways reaches a point where it is no possible to take air into the lungs. If action is not taken to reduce the swelling of the airways in order to restore breathing, someone could die of asphyxiation, or the lack of oxygen. The number of people being diagnosed with asthma is on the rise, especially in the rates of children developing symptoms of asthma at a young age.

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

Asthma is a chronic respiratory disease that is not to be underestimated; it affects approximately 12.1% of children in the United States (English et al. 2006). Asthma is particularly concerning and threatening to children for multiple reasons, one being the anatomy of children. Asthma has no cure however there are some ways to treat asthma. If gone untreated, asthma could be deadly. Many causes of asthma cannot be exterminated however they can be reduced. Air pollution, being one of them, is something that many people may consider to be unavoidable, but in reality it is an unfortunate result of a luxury that the majority of the population consider a necessity.

Imagine yourself on a cold, gloomy “Winter night” being awakened by the endless chest pain and the persistent abnormal breathing that you’ve had to deal with all night. And then it occurs “have you ever heard about a fish without water not being able to breath” that’s how it feels to have asthma or experience an attack at least. I was diagnosed with asthma when I was approximately ten years old which gave rise to a new fear not knowing when or where I might experience another asthma attack. Because I want to be a nurse anesthetic in the future, I want to learn more about one of the diseases that I have, I also want to learn more about its symptoms, diagnosis, and or treatment.

Asthma is a chronic inflammatory disorder of the airways that lead to difficulties in respiration (Kaufman & Kent 2015). It occurs when airways are over-sensitive and easily respond to a variety of intrinsic and extrinsic stimuli such as allergens, smoke, stress, emotions, medication, weather, exercise, and colds or the flu (Kaufman & Kent 2015). These triggers can offset common asthma symptoms including coughing, wheezing, chest tightness, and shortness of breath (Kaufman & Kent 2015). The type of trigger, severity, and timing of an asthma attack is unpredictable and different for everyone. In the case study, Joseph has had episodes of acute exacerbation reducing in severity in the early phases but has not experienced an attack for the last

Answer-: Asthma is a chronic inflammatory airway disease. Its characterized by obstruction, hyperinflation, mucus secretion that’s leads to mucus plug formation, limitation of airflow.

What is asthma? The medical description of asthma is simple, but the condition itself is quite complicated. Asthma is a respiratory condition evident by contractions in the bronchi of the lungs, affecting one’s ability to breathe properly. Initially, the earliest medical record of asthma was found in China in 2400 BC. The history of the discovery of asthma as a serious respiratory disorder came to light in 400 BC, and Hippocrates first used the term ‘Asthma’ in his book ‘Corpus Hippocraticum’ where he also specified a definition for the medical term. I personally chose to study this disease because I have personally seen this condition present in many people from the evidence of their inhalers, and studies show that asthma rates are continuing to rise each day for a number of theories. Experts have classified asthma into certain groups ranging from least severe to most severe:
