Asthma Research Paper

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

Frequent coughing especially at night airways tend to narrow, which causes increased airflow resistance. Losing your breath easily or shortness of breath is caused by “grit” which accumulates in the air passageway because of an overload due to imcomplete filtering. Wheezing during physical activities. Wheezing is caused by increased responsiveness of the trachebronchial tree to various stimuli.

In addition, asthma affects the smooth muscle walls and glands of the bronchioles, due to narrowing of the bronchial passageway, this results in a build-up of mucus in the bronchial tubes leading to difficulty breathing (Rizzo 2016, p.423). Airflow in the alveoli becomes limited due to inflammation causing bronchoconstriction, as the inflammatory process begins mast cells degranulate and release inflammatory mediators (Kaufman 2012, pp.589-590). ‘The inflammatory process results in vascular congestion, production of thick mucus, bronchial muscle spasm and thickening of the airway walls’ resulting in Jessica becoming short of breath and coughing (Kaufman 2012, pp.589-590). Typically, this reaction occurs 30 to 60 minutes after being exposed to the triggering allergen or irritant (Kaufman 2012, pp.589-590). Asthma can be triggered by a range of different factors including exercise, infection, exposure to allergens or airborne substances such as dust, fumes or pollen (Rizzo 2016, p.843). However, some asthma attacks may be worse than others, this is because a severe asthma attack can completely narrow and close the airway (Lew 2011, pp.43-45). This can result in oxygen not getting to vital organs such as the heart or brain and can result in

Your airway has smooth muscles around the outside of the airway tubes also known as bronchial tubes. The tubes are open allowing air to flow freely; during an asthma attack those muscles begin to tighten that is called a bronchospasm restricting the airflow. During an asthma attack the lungs also become inflamed and the mucus in the tubes begins to become thicker and builds up, this makes it even more difficult for air to pass through the opening of the tubes. With the airway being restricted and the mucus build up causes a wheezing sound and shortness of breath and difficulty in inhaling and exhaling air (WebMD).

The good thing about asthma is that there are a lot of medications available to help treat asthma sufferers with acute onset of symptoms as well as help with the long term prognosis of patients. Asthma medications are classified into two groups, Controller and quick-relief. Controller medications are designed to help prevent asthma attacks. Their purpose is to try and reduce the chronic inflammation thus making the body less likely to react to triggers. Some of these include long-acting beta-agonists, Leukotriene modifiers, Mast cell stabilizers, Theophylline, and immunomodulators. Long-acting beta agonists are bronchodilators that assist in opening up your airways. These are normally aerolized medications. The bronchodilator causes the muscles

1.2. During an asthma attack, the air passages become narrow, their surrounding muscles tighten, and stickier mucus is produced. Patients experience symptoms like coughing, wheezing, chest tightening and breathlessness. Severe asthma attack can cause restriction of oxygen into the lungs and bloodstream (British Lungs Foundation, 2014). This can be dangerous and life threatening if immediate medical treatment is not received. Asthma symptoms are usually severe at night (NHS Choice, 2014). This can disturb patient’s sleep and can affect their behaviour and concentration. Asthma can also affect the patient ability to do physical exercises as well as their daily routine.

Asthma affects breathing through the airways in the lungs. The airways constrict and build up with mucus, making little room for air to come in and out. "Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing."

difficulty in breathing. It can result from an allergic reaction or other forms of hypersensitivity. It is

Asthma causes may include allergens, environmental irritants, respiratory illnesses, sulphites in food, reflux, or medications like beta blockers.2 The airways of asthmatics are narrowed due to the plugging by accumulated mucus, and smooth muscle contraction. During inspiration, the diaphragm moves downwards into the abdomen, and the ribs move upward and outward movement due to diaphragm and inspiratory intercostal muscles’ contraction respectively. This enlarges the lungs due to the changes in intrapleural pressure, and expands the alveoli. Hence, airway resistance decreases during inspiration, because, as the lungs enlarge, the airways within the lung are subject to the same forces as the alveoli, becoming widened. During passive expiration, the inspiratory intercostal muscles relax, causing the lungs to recoil. During active expiration, expiratory intercostal muscles and abdominal muscles contract, decreasing thoracic dimensions, and increasing

sthma is inflammation of the bronchial tubes with increased production of sticky secretions inside the tubes. People who have asthma experience some of the common symptoms which are coughing, wheezing, shortness of breath, chest tightness, pain or pressure in the chest. Some people with asthma may experience asthma attacks frequently and others can go for extended periods without symptoms. When a MA is taking vitals your asthma could reflect on your vitals. They could hear the wheezing.

Asthma patients have difficulty in breathing normally because of a severe lung condition. They develop extra sensitive airways in their throat and narrowing. when airways and throat become damaged or irritated, the result is making the air difficult to move in and out, and this causes Wheezing, Coughing, Shortness of breath, And a tight chest. In the normal condition, the muscle band at the outside of the airways are very relaxed. Also, the inside opening of the airways is wide open so the air can move in and out very easily. When a person develops asthma, the gas exchange becomes difficult to maintain normal rate. There are three things that can happen to the asthmatic patient, first, the muscle bands get tighten, inflammation of the airways

Asthma is an allergic disorder of respiration, characterized by bronchospasm, wheezing, and difficulty in expiration, often accompanied by coughing and a feeling of constriction in the chest. Currently, there are 26 million Americans affected by asthma— 19 million adults and 7 million children — and Asthma becomes one of the leading causes of absences from work and school. Asthma often runs in families; according to the World Health Organization, about half the cases are due to genetic susceptibility and half result from environmental factors. The most common signs of asthma are: coughing (especially at night, during exercise or when laughing), difficulty breathing, chest tightness, shortness of breath and Wheezing (a whistling or squeaky sound

Asthma is a long-term medical condition that affects the airways. When a person has asthma the walls of the air tubes that transport the air in and out of the lungs become irritated and swollen. In this condition, the air tubes get smaller and the cells produce more mucus than usual clogging the air tubes and preventing the air to reach the lungs. This disease makes the airways very sensitive, in consequence they may be greatly affected by any allergic reaction a person may have. Asthma affects people of all ages, there is an average of 25 million people affected by this condition in the united states. People that have a family history with asthma and allergies are more likely to have this condition.

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 disease involving the respiratory system causing obstruction to the airways. During an acute attack of asthma, the circular muscles surrounding the breathing tubes that form our airways( called the bronchi) go into spasm impending especially the passage of air starvation. One is surrounded by so much air , the patient finds it difficult to get enough. Also at this same time, there is increased secretion of mucous by the inner lining of the bronchial tubes adding to the obstruction of the
