AsthmaCenters for Disease Control, Asthma, FAQsWhat Asthma Is1 Asthma is a disease that affects your lungs. It is the most common long-term disease of children. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing.2 We know that family history contributes to susceptibility, but in most cases we don’t know what causes asthma to develop, and we don’t know how to cure asthma. You can control your asthma by knowing the warning signs of an attack, avoiding things that trigger an attack, and following the advice of your doctor.Effects of Asthma3 In 2001, 20.3 million Americans had asthma, and 12 million had had an asthma attack in the previous year. If a person has a parent with asthma, he or she is three to six times more likely to develop asthma than is a person who does not have a parent with asthma.How Asthma Is Diagnosed4 Asthma can be difficult to diagnose, especially in children under 5 years old. Regular physical exams that include checks of lung function and for allergies can help make the right diagnosis.5 A health-care provider trying to diagnose asthma will ask you questions about coughing, especially coughing at night, and whether breathing problems are worse after physical activity or during a particular time of year. Providers also ask about other symptoms, such as chest tightness, wheezing, and colds that last more than 10 days.6 Also, a provider will ask about your family history of asthma, allergy and other breathing problems, and your home environment. He or she also will ask about lost school or work days and limits on your activity.7 Testing of lung function, called spirometry, is another way to diagnose asthma. A spirometer is a piece of equipment that measures the largest amount of air you can exhale after taking a very deep breath. Airflow can be measured before and after you use an asthma medication.What An Asthma Attack Is8 Airways are the paths that carry air to the lungs. As the air moves through the lungs, the airways become smaller, like branches of a tree. During an attack, the sides of the airways in your lungs become inflamed and swollen. Muscles around the airways tighten, and less air passes in and out of the lungs. Excess mucus forms in the airways, clogging them even more. The attack, also called an episode, can include coughing, chest tightness, wheezing, and trouble breathing.Causes Of An Asthma Attack9Environmental exposures, such as house dust mites and environmental tobacco smoke, are important triggers of an attack. Some of these triggers are listed in the box below.How Asthma Is Treated10 You can control your asthma and avoid an attack by taking your medicine as prescribed and avoiding the triggers that can cause an attack. It’s just as important that you remove the triggers in your environment that you know make your asthma worse.11 Medicine for asthma is different for each person. It can be inhaled or taken as a pill and comes in two types—quick-relief and long-term control. Quick-relief medicines control the symptoms of an asthma attack. If you are using your quick-relief medicines more and more you should visit your health-care provider to change your asthma management plan. Long-term control medicines make you have fewer and milder attacks, but they don’t help you if you’re having an attack.Important Asthma Triggers:Dust Mites12 Mattress covers and pillow case covers provide a barrier between house dust mites and the person with asthma. Down-filled pillows, quilts, or comforters should not be used and stuffed animals and clutter should be removed from bedrooms.Pets13 Furry pets may trigger an attack. The simplest solution to this situation is to find another home for the pet. However, some pet owners may be too attached to their pets or unable to locate a safe new home for the animal. Any animal causing an allergic reaction should not be allowed in the bedroom. Pets should be kept outside as much as possible and bathed weekly. People with asthma are not allergic to their pet’s fur,so trimming the pet’s fur will not help your asthma. Frequent vacuuming will reduce the presence of the allergen. If the room has a hard surface floor, it should be damp mopped weekly.Mold14 When mold is inhaled, it can cause asthma attacks. Eliminating mold throughout the home can help control asthma attacks. Keep humidity levels between 35% and 50%. In hot, humid climates, this may require the use of air conditioning and/or dehumidifiers. Fixing water leaks and cleaning up any mold in the home can also help.QuestionThe author's purpose in including paragraphs 12, 13, and 14 isResponsesA to show that asthma can be cured.to show that asthma can be cured.B to explain how asthma affects the lungs.to explain how asthma affects the lungs.C to remind asthma sufferers to take their medication as prescribed.to remind asthma sufferers to take their medication as prescribed.D to suggest steps the asthma sufferer can take to avoid asthma attacks.

An 18-year-old girl is brought in to the hospital by her parents because of an asthma attack. She normally takes inhaled fluticasone and albuterol; however, she is not currently responding to the albuterol. On examination, she appears anxious and is moderately short of breath. There are loud bilateral wheezes on examination, with a prolonged inspiratory and expiratory phase and use of accessory muscles of respiration. Her temperature is 37.6°C, blood pressure is 118/78 mmHg, heart rate is 106 beats per minute, respiratory rate is 26 breaths per minute, and oxygen saturation is 93% on room air.
