How Is It Treated
There are two parts to treating asthma, which are outlined in your asthma action plan. The goals are to:
- Control asthma over the long term. Your asthma action plan tells you which medicine to take. It also helps you track your symptoms and know how well the treatment is working. Many people take controller medicineÃ¢usually an inhaled corticosteroidÃ¢every day. Taking it every day helps to reduce the swelling of the airways and prevent attacks. Your doctor will show you how to use your inhaler correctly. This is very important so you get the right amount of medicine to help you breathe better.
- Treat asthma attacks when they occur. Your asthma action plan tells you what to do when you have an asthma attack. It helps you identify triggers that can cause your attacks. You use quick-relief medicine, such as albuterol, during an attack.
If you need to use the quick-relief inhaler more often than usual, talk to your doctor. This may be a sign that your asthma is not controlled and can cause problems.
Asthma attacks can be life-threatening, but you may be able to prevent them if you follow a plan. Your doctor can teach you the skills you need to use your asthma action plan.
Serial Peak Flow Monitoring
Measurement of peak flow involves having the patient take in as deep a breath as possible and blow it out as hard and fast as possible into the measuring device . The test measures the fastest rate of expired airflow.
The following peak flow parameters support a diagnosis of asthma:
Diurnal variation in peak expiratory flow of more than 20%
An improvement of at least 60 L/min or at least 20% after inhalation of a rapid-acting bronchodilator
Peak flow measurement is much simpler and cheaper than spirometry and can be used by patients for self-monitoring at home or in the workplace. However, unlike spirometers, peak flow meters do not measure flow rates over time, nor do they measure lung volumes. Furthermore, there is great variation in readings from peak flow meters and in their reference values. Hence, they are not highly reliable for either children or adults. Patient compliance with self-monitoring may also be an issue. Furthermore, peak expiratory flow is less sensitive to changes in airway calibre than is FEV1. Therefore, it is preferable to use peak flow meters only for monitoring asthma, not for diagnosis.

How Old Does A Child Have To Be To Have Asthma
Treating asthma in children under 5. In infants and young children, the primary symptoms of asthma wheezing and coughing may be caused by other conditions. Also, standard diagnostic tests used to measure how well someone is breathing cannot be used easily or accurately with children under age 5.
What Can An Allergist Do For A Child With Asthma
An allergist can set your child on the right track for long-term control by helping you create an action plan with treatment goals for your child. With the right treatment, your child can sleep through the night, avoid missing day care or school and breathe more easily.
Asthma symptoms may be triggered or worsened by certain events: Colds or other respiratory infections. Allergy-causing agents , such as dust, pet dander or pollen. Activity or exercise. In infants, feeding. Exposure to cigarette smoke or other airborne irritants.

What Are The Different Lung Function Tests For Asthma
There are several lung function tests for asthma. The most common include:
Bronchodilation And Bronchoprovocation Tests
These tests gauge how well the lungs respond to either a quick-relief asthma medication or an intentional disturbance to normal airflow. They usually are done if spirometry is normal in spite of asthma symptoms.
- Bronchodilator responsiveness testing: A bronchodilator is a fast-acting medication that provides quick relief of asthma symptoms. This test involves administering a bronchodilater and, 10 to 15 minutes later, repeating an initial spirometry test and comparing the results. If the medication brings about an increase in airflow of 12%, it is an indication that asthma is the cause of symptoms.
- Bronchoprovocation challenge testing: This test involves inhaling either aerosolized chemicals or cold air, or performing exercises, to see if it induces asthma symptoms. By measuring lung function after exposure to these triggers, a doctor may be able to diagnose asthma.

What Are The Signs And Symptoms Of Asthma
Asthma is a lung condition that causes shortness of breath and difficulty breathing. It can be triggered by several things, including airborne allergens and physical exertion. Signs and symptoms of asthma include the following:
- Low tolerance for physical exercise
Many of these symptoms can be caused by other ailments , but you should consider being tested by a doctor regardless. Allergies often act as asthma triggers, making it a dual problem.

How Do Doctors Diagnose Asthma
To determine whether or not you have asthma, your doctor will probably ask you some medical questions, including about your familys medical history.Asthma can be hereditary , so knowing your familys health history can indicate whether its a possibility for you.
The doctor will also ask about symptoms, triggers, exercise habits, etc. Once all of the basic questions have been answered, your doctor will perform a physical exam.
Asthma Signs & Symptoms
People with asthma experience symptoms due to inflammation in the airways. They might only occur when you encounter an asthma trigger. Common symptoms that can lead to a diagnosis of asthma include:
- Persistent or recurring coughing: which often occurs at night or early in the morning, although it can happen at any time. Coughing is a major feature of asthma, especially in children and can sometimes be the only sign of asthma.
- Wheezing: is difficulty breathing accompanied by a whistling sound coming from your airways
- Shortness of breath: gives you the feeling that you cant get enough air into your lungs, and may even find it difficult to eat, sleep or speak
- Chest tightness: an unpleasant sensation of heaviness or pressure in the chest that can make it hard to breathe
- Increased mucus production: is characterized by high levels of thick fluid or phlegm accumulating in your airways
- Difficulty breathing while exercising: having trouble breathing while performing physical activities can be a sign of asthma
- Losing Sleep: Being unable to sleep through the night because of breathing troubles

What Are Pulmonary Function Tests
Pulmonary function tests include numerous procedures to diagnose lung problems. The two most common lung function tests used to diagnose asthma are spirometry, exhaled nitric oxide and challenge tests.
Spirometry This is a simple breathing test that measures how much and how fast you can blow air out of your lungs. It is often used to determine the amount of airway obstruction you have. Spirometry can be done before and after you inhale a short-acting medication called a bronchodilator, such as albuterol. The bronchodilator causes your airways to expand, allowing for air to pass through freely. This test might also be done at future doctor visits to monitor your progress and help your doctor determine if and how to adjust your treatment plan.
Exhaled nitric oxide Nitric oxide is a gas that is produced in the lungs and has been found to be an indicator of inflammation. Because asthma is an inflammatory process, this test has become helpful in the diagnosis and management of asthma. The test is performed by having you breathe into a small, handheld machine for about 10 seconds at a steady pace. It then calculates the amount of nitric oxide in the air you breathe out.
Box 4 Key Messages For The Diagnosis Of Asthma In Adults
The diagnosis of asthma should be suspected in patients with recurrent cough, wheeze and dyspnea in whom no alternative diagnosis can be found and should be confirmed by an objective measurement of lung function or, if normal, by tests for bronchial hyperresponsiveness .
A clinical diagnosis of asthma should be prompted by symptoms such as episodic breathlessness, wheezing, cough, sputum and chest tightness .
Measurements of lung function by spirometry or peak expiratory flow provide an assessment of the severity of airflow limitation, its reversibility and its variability, and can be used to confirm the diagnosis of asthma .
Measurements of allergic status can help to identify risk factors that cause asthma symptoms in individual patients .
Because the obstruction observed in asthma is variable, it is possible for the spirometry results to be normal for a patient who has asthma. Options to confirm asthma include bronchial challenge tests, serial peak flow monitoring and measurements of inflammation .
For patients with symptoms consistent with asthma who have normal lung function, measurement of airway responsiveness may help to establish the diagnosis .
Challenge testing is potentially useful in patients with typical symptoms but normal spirometry results or atypical symptoms or possible occupational asthma .

Question : Do Your Symptoms Get Worse When You Go Out In The Garden Or Are Near Pets
You answered yes.
You answered no.
- A worsening of asthma symptoms is known as an asthma exacerbation, or more commonly, as an asthma attack. These are induced by triggers stimulus that cause increased severity of symptoms.
- Triggers are often something airborne that inflame the bronchi when they come into contact with them.
- Common triggers include allergens such as pollen, pet hair, or dust, but an asthma attack can also be triggered by non-allergic reactions, such as to cigarette smoke, exhaust fumes, certain foods or medicines, or an abrupt change in the weather.
- An attack can even be brought on by stress a number of changes in the body take place when were under pressure, which can lead to increased chest tightness and heavy breathing.
- The body also releases chemicals in periods of stress, such as leukotrienes and histamines, which can cause inflammation of the airways.

Diagnosis Of Asthma In Children
Its often difficult to diagnose asthma in children under 5, particularly as they find breathing tests difficult.Your doctor will assess your childs symptoms and your explanation of their symptoms, and may give your child asthma medicine to measure its effect this iscalled a treatment trial. Your doctor will monitor the effect this medicine has on your child and will use the results as part of their diagnostic process.
To Confirm The Diagnosis The Following Tests May Be Performed
- Spirometry: a simple breathing test that gives measurement of lung function including a reversibility test that measures lung function before and after a dose of reliever to see if the medication has improved your lung function.
- Peak Expiratory Flow Rate : this is another simple breathing test which may be measured over a period of time such as when one has symptoms or is symptoms free. It can be performed by a G.P., in a hospital or even at home.
- Exercise Testing: this test is used to check if exercise makes your symptoms worse.

How To Tell You Have Asthma
Asthma is a complex disease to diagnose, and only a healthcare professional is able to make a proper diagnosis.
If you are concerned that you may have asthma, contact your healthcare provider. In order to confirm an asthma diagnosis, your healthcare provider will take into account your medical and family history, allergies, and conduct lung function testing such as spirometry.
Gaps In Knowledge And Future Directions
Other testing approaches may be part of future algorithms. Measurement of inflammatory markers such as sputum eosinophils or exhaled nitric oxide is already being used in some settings to evaluate asthma control and formulate management decisions. However, although such tests show clinical promise, they have not yet been rigorously investigated for use in the diagnosis of asthma and are currently limited to tertiary care centres and research facilities.
A 10% or more fall in FEV1 from baseline is considered an abnormal response following hyperventilation with dry air, as is a fall of 15% from baseline following challenge with hypertonic aerosols. For adenosine monophosphate, a 20% or greater fall in FEV1 at a concentration of less than 400 mg/mL is considered abnormal. Furthermore, a positive response to bronchial provocation by eucapnic voluntary hyperventilation is considered acceptable confirmation of exercise-induced asthma it is in fact the current standard of the International Olympic Committee, although it is not often used in other settings.
In the future, genetic testing may allow individually targeted diagnostics and therapeutic decisions.,

Spirometry Helps Diagnose And Manage Asthma
A spirometry test can confirm whether you have asthma or another disease. And it helps your healthcare provider decide on your treatment. A spirometry test can also show how well your treatment is working. If follow-up spirometry tests show that your asthma is well controlled, your treatment is working. If it shows that your asthma is not under control, your doctor may need to change your medicine or give you more medicine.
