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.…
I already knew that asthma is a chronic disease which affects the lungs and that…
Asthma can be well controlled with the appropriate medication in almost all people. The main types of medication are:…
Before a patient is diagnosed with asthma they have to go through a number of tests to determine if they in fact have asthma. Lung Functioning tests and allergy tests are often used to diagnose asthma (WebMD, 2014).…
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).…
Asthma is a condition that can affect the airways, it a small tubes that carry air in and out of the lungs. The airways becomes very sensitive, they react to things that can cause problem, such as cold or dust. Muscle around the wall of the airway tighten up and makes It narrow and very difficult for the airway to flow in and out. This cab make the lining of the airways to get swollen and sticky mucus produce. When the airways is narrowed it get very difficult for air to move in and out and that when the chest has to work so…
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…
Treatment usually involves learning to recognize your triggers, taking steps to avoid them and tracking your breathing to make sure your daily asthma medications are keeping symptoms under control. In case of an asthma flare-up, you may need to use a quick-relief inhaler, such as albuterol.Medications for you depend on a number of things, your age, symptoms, asthma triggers and what works best to keep your asthma under control. Some long-term asthma medications that are given/recommended-…
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…
A long term control drugs for asthma are used to prevent symptoms for people with moderate to severe asthma. Inhaled steroids prevent symptoms by not allowing the airways to swell. Also, long-acting beta-agonist inhalers will help prevent asthma symptoms as well. A quick relief (rescue) drugs work really fast to control asthma symptoms. Short-acting bronchodilator inhalers like Proventil, Ventolin, and Xopenex may help with asthma symptoms too.…
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. A condition in which one has trouble breathing because of a narrowed airway. It is classified as a lung disease and has symptoms such as shortness of breath and coughing (National Institute of Health, 2014).…
Bronchial asthma can be placed under the category of chronic diseases. As such, a person suffering from bronchial asthma should always be under constant medical supervision. Depending upon the causing factors, bronchial asthma may or may not be curable in a complete manner. However, avoiding the asthma triggers, external causes like allergies and proper treatment can let its patient lead a fairly normal life. Basically, two types of drugs are given for bronchial asthma treatment.…
