Asthma is a chronic breathing problem that affects nearly 5 million children in the United States. It is caused by swelling and closing of the airways inside the lungs which makes it hard to breathe. There are many reasons that kids can have asthma "attacks". These things are called triggers; some triggers might consist of: Pollen from trees, grass, and other types of plants. Also; mold, dust, weather changes, perfume, pet fur, smoke and exercise. There are many more things that can trigger asthma. When you have an asthma attack the muscles around the airways tighten making the airways smaller which causes you to have difficulty breathing. Asthma does not have a cure but there are many methods to keeping your asthma under control. Taking your medication as directed and knowing when you are having an asthma attack are the two most important things you can do to keep control of your asthma.
There are many symptoms you can see in your child who has asthma. When these symptoms appear, it is important to be proactive and seek medical attention. Some asthma symptoms may include: coughing that gets worse at night, wheezing, shortness of breath, or tightness in your chest. It is

important that your child knows what triggers their asthma and also has a quick relief inhaler and spacer in case of an asthma attack. After seeking your doctor, they will create and asthma plan of action for your child.
Its is a plan for your child to follow to keep their asthma under control. This plan is individualized to each patient. Your child will be prescribed bronchodilator medication. Bronchodilators open your airways. They relax the muscles around the airways that get tight during an asthma attack. If exercise causes symptoms for you, take a quick relief medicine 15 minutes before exercise. There are two types of this medication: Metered dose inhalers (with spacers) and Nebulizers. Like all medication, bronchodilators can cause side effects. Some may include: increased heart rate, jitteriness, and nausea. If your side effects continue 15-20 minutes after administration, consult your
doctor. Taking your medication and taking it correctly is very important to control your asthma. You should always use a spacer whenever you use a metered dose inhaler. If you do not use a spacer, the medicine may end up on your tongue, on the back of your throat, or in the air which causes you to not get the full amount needed. A spacer holds the medicine in its chamber long enough for you to inhale slowly. Knowing how to use a metered dose inhaler and spacer is very important, you should: 1.)Remove the cap on the inhaler and hold it upright, 2.) Shake the inhaler to mix the medication, 3.) Inhale and breathe out, 4.) place the mouthpiece in your mouth, 5.) push one puff of medicine into the spacer and then inhale slowly, 6.) hold your breath for 10 seconds after to allow the medication to spread then breathe out slowly through your nose. It is important to always wait a minute in between puffs if ordered to do more than one by the doctor. Clean your inhaler and spacer weekly to prevent buildup and clogging. In conclusion, it is important to stay on top of your treatment plan to keep control of your asthma. Make sure to bring your action plan and peak flow meter sheet to each visit with your healthcare provider so they are able to view your progress or if something should be changed in your treatment. Asthma can become a serious problem if not treated correctly. If you keep up with your medication schedule or know what to do in case of an emergency, you can live everyday life without having fear of an attack.
Aims: To implement a multi-pronged strategy that (1) educates parents, students, and school staff about asthma and its management, (2) establishes comprehensive asthma screening programs, (3) develops affordable and long-term management strategies for students with asthma, and (4) increases the rigor of school inspections with regards to air quality and other common asthma triggers.
Asthma is a chronic inflammatory disease of the airways. It is a reversible airway obstruction, occurring 8 to 10% of the population worldwide. According to a study in 2005, asthma affects over 15 million Americans, with more than 2 million annual emergency room visits. Asthma patients have a hyper-responsiveness in their airways and generally and increase in their airway smooth muscle cell mass. This hyperplasia is due to the normal response to the injury and repair to the airway caused by exacerbations. The main choice of therapy for asthma patients is β2- adrenergic agonists. Racemic albuterol has been the drug of choice for a short acting bronchodilator for a long time, but since the development of levalbuterol, there is the question of which drug is a better choice for therapy. Efficacy and cost of treatment must both be taken into consideration in each study of these therapies to determine which is best for the treatment of asthma.
There are two forms of bronchodilators, a short acting and a long acting form. Short acting relieves or stops asthma symptoms and is very helpful during an attack. They are also called ‘rescue’ medications because they are best for treating sudden or severe asthma symptoms. Long acting bronchodilators are used to control asthma, they take longer to work but they also last longer, up to 12 hours, whereas a short acting would only last for about 4-5 hours. Ventolin is a short acting form, it is the recommended medication to use 15-20 mins before exercising.
Asthma is treated with two types of medicines: long-term control and quick-relief medicines. Long-term control medicines help reduce airway inflammation and prevent asthma symptoms. Quick-relief, or "rescue," medicines relieve asthma symptoms that may flare up.
...pecific leukotriene receptors on bronchial tissues, therefore preventing bronchoconstriction, mucus secretion, and oedema. These treatments also reduce the influx of eosinophils, which results the ability to limit inflammatory damage being caused in the airway. These oral, non-steroidal, anti-inflammatory drugs reduce the incidence of acute asthma attacks when taken on a regularly basis. Although in cases of acute asthmatic attacks medical intervention and treatment is required. The type of intervention depends on the severity of the attack itself.

Imagine a young child competing with his or her fellow classmates during recess and immediately losing the ability to breathe normally. He or she stops in the middle of the competition and falls to the ground while holding his or her chest trying to find air. When you are young, being able to keep up with your peers during recess and sporting events is very important, however, having asthma restricts this. Asthma has a significant impact on childhood development and the diagnosis of asthma for children 18 years and younger has dramatically increased over the years. Asthma is known as a “chronic inflammation of the small and large airways” with “evident bronchial hyper-responsiveness, airflow obstruction, and in some patients, sub-basement fibrosis and over-secretion of mucus” (Toole, 2013). The constant recreation of the lung walls can even occur in young children and “lead to permanent lung damages and reduced lung function” (Toole, 2013). While one of the factors is genetics, many of the following can be prevented or managed. Obesity, exposure to secondhand smoke, and hospitalization with pneumonia in the early years of life have all been suggested to increase children’s risk of developing asthma.
Asthma is chronic inflammatory disorder of the airways characterized by recurring episodes of wheeling and breathlessness. It often exists with allergies and can be worsened through exposure to allergens. In fact, asthma is complicated syndromes that have neither single definition nor complete explanation to the point. In light of its treatment, it is worthwhile to notice that asthma cannot be cured, instead can be only managed by avoiding exposure to allergens and/or by using medications regularly.
First of all, people may feel anxious when they suddenly have an asthma attack. It is a quite frightening experience because people with asthma have very sensitive airways. If something irritates the airways of a person with asthma, the airways become red and swollen, and this may be even more difficult for air to pass through the airways into the alveoli and out again . People became breathless and breathed more frequently that make them feel more anxious.
Asthma symptoms can range from mild to very severe. A person may experience only occasional severe episodes one time and then experience frequents mild episodes. According to the book, Living Well With Asthma, there are four main symptoms of an asthma attack. Since an attack can be so overwhelming and frightening, it may be difficult to know what’s going on inside of a persons body. Here are the major elements of an asthma attack:
Even though there is no cure for asthma, there are two main types of medication used for the treatment of it. The first is long term medication that aids in decreasing the inflammation of a person’s airways and also serves as a preventative measure for symptoms and asthma attacks. These medicines are usually anti-inflammatory drugs that are taken daily to reduce future symptoms, but do not act as a quick fix...
There are many symptoms of asthma which include; wheezing (sounds like a whistling sound), chest tightening, shortness of breath, and coughing. Asthma usually results from an allergic reaction or other forms of hypersensitivity. People who have a family history of asthma have an increased risk of developing the disease. Allergies and asthma often occur together, along with eczema. Smoking when you have a diagnosis of asthma is a dangerous combination, which is still seen commonly. Asthma may occur at any age, although it's more common in people under age 40. There are many different ways that people can be affected by asthma with allergies; especially when combining them with tobacco smoke, environmental factors, obesity, pregnancy, stress, and genes.
This paper throughly explores the care administered to the cases study Zachy a seven year old boy who has presented to the hospital following the an exacerbation of asthma. Discussed throughout is the pharmacological management of Zachy’s asthma including the pharmacodynamics of these prescribed medications and what affect these medications have on the pathophysiology within the respiratory tract.
“I don’t think of inhalers as medicine. I bring it out everywhere; itis like a wallet, or cash,” said Vaillancourt, who suffers from mild asthma. “If I don’t bring it out, I panic and actually make my asthma
Asthma is a disease of the respiratory system. It causes swelling and narrowing of the air tubes inside the lungs. When this happens there can be coughing, a whistling sound when you breathe (wheezing), chest tightness, and difficulty breathing. The narrowing comes from swelling and muscles spasms of the air tubes. It is a common illness of childhood. Knowing more about the illness can help patient handle it better. It cannot be cured, but medicine can help control it.
