How Does an Asthma Inhaler Work?

A person suffering from asthma, will have an attack, when ones immune system reacts to the inhalation of various irritants. These irritants can take the form of dust, smoke, and even cold weather. Stress can also cause an attack of asthma. This irritation activates the immune system and causes inflammation of the nasal pathways. It also causes the muscles at this area to become constricted. This leads to the near closure of the airway and causes wheezing and breathing trouble. The immune system causes mucus to build up in the lungs, and an asthma patient, will experience a coughing fit.

The portable asthma inhaler aids in providing the required drug to alleviate the asthma attack. The asthma inhaler works by reducing the inflammation in the airways. The inhaler delivers the required dosage to the patient. The drug can be delivered by inhaling through the mouth or nasally. The drugs used will depend on the asthma attack faced by the person.

There are various types of inhalers and can be classified as pressurised metered dose inhalers (MDIs), breath-activated inhalers - MDIs and dry powder inhalers, inhalers with spacer devices and nebulizer.

The pressurised metered inhalers use an inactive gas to inject the drug. Pushing down the top of the inhaler, releases the drug and it has to be inhaled. It is also small and easy to carry. Some inhalers have meters which can indicate the number of doses that remain for use. Otherwise, one will have to count the doses to keep track. The drawback is that, it requires coordination, as the person has to press down and inhale at the same time.

The drug is discharged by just breathing on the mouth piece and is easier to operate than the pressurised one. Though, Inhalation has to be done forcefully for the drug to be released.

Inhalers with spacer devices are much easier to operate than the other kinds. Inhaling through the mouth piece causes the spacer to releases the drug. A valve stops the drug from exiting the spacer when one breathes out. In some types of spacers, a face mask can be fitted instead of a mouthpiece.

Nebulizers convert the drug into the form of a mist. This can be breathed in with a face mask or mouth piece. This drug delivery system is used in hospitals where there are severe cases of asthma.

One must consider several issues, before choosing inhaler for use. This is because, some medications can only be used with certain of inhalers. People suffering from asthma should take adequate precautions to avoid being exposed to stressful situations, dirt, dust, smoke, or anything that can trigger an attack. In choosing the right inhaling mechanism, they can overcome an asthma attack. Providing quality reviews, articles and writings on asthma online.

How Doctors Accurately Diagnose Asthma

The diagnosis of an asthma patient can depend on the symptoms presented, a detailed medical history, the physical examination done by the doctor and the laboratory tests done to confirm the diagnosis. For the most part the diagnosis of asthma can be fairly easy once the results come through; however, the diagnosis has an involved process before the eventual results are determined.

For asthmatic patients symptoms can include problems related to breathing such as difficulty taking a breathe, wheezy respiration, labored breathing during activities that require exertion, chest tightness and any obstruction of airflow. A true indicator for asthma can be seen when the person gasps for breath with a wheezy sound, which is a characteristic picture of asthma. In addition, having a detailed medical history that includes any history of allergy, family history of asthma, persistent coughs, cold and seasonal allergies can be contributing factors for asthmatic patient.

After the diagnosis process has begun laboratory tests are usually ordered to confirm that the patient has asthma and can include blood tests for ESR and eosinophil counts that could give indication of any allergic reaction or chest infection, as these are also contributory factors. The chest x-ray confirms the expansion of the lungs as well as any infections or other abnormalities in the lungs that can contribute to asthma. The groups of tests performed to diagnose asthma are Pulmonary Function Tests, otherwise known as Spirometry. In this test the degree and access of airflow obstruction is measured along with the confirmation of its severity. These are otherwise termed FEV1, FVC, and FEV1/FVC. The assessment of the reversibility of asthma can also be done through these tests. Carrying out tests of allergen detection through skin sensitivity tests is also a form of testing. These tests are of prolonged duration by which time the person has a fully established asthma. Still, if the allergens detection is accurate and the person needs to stay away from certain allergic substances, then asthmatic attack is preventable.

One of the most experienced symptoms of asthma is a wheezing sound as air enters the respiratory system. Many other chest diseases can present the same types of breathing problems as asthma; hence an accurate diagnosis is very essential. Spirometry is the confirmatory lung test for asthma. Once the diagnosis is made, the options open to the patient vary in range from no prescription, for very mild cases of asthma, to a full course of asthmatic preventatives to help those patients who have a severe asthmatic problem.

People who have asthma should always keep up-to-date on the newest asthma treatments and other preventative measures for asthma attacks, such as air purifiers and leukotriene modifiers. Providing quality reviews, articles and writings on asthma online.

5 Healthy Tips for Bronchial Asthma and Chronic Obstructive Pulmonary Disease

With the holiday season fast approaching and with added travel and holiday stress, a change in sleeping behavior may affect your asthma or chronic obstructive pulmonary disease (COPD). Here are some helpful tips this holiday season that may help prevent exacerbation of asthma or COPD. The common symptoms of bronchial asthma are nighttime cough, wheezing and shortness of breath. The common exacerbation cause of bronchial asthma is respiratory tract infection, postnasal drip, gastroesophagel reflux disease (GERD) or heartburn.

1. Sleep adequately. You will want to sleep a little longer and go to bed earlier by the start of the holiday season if you feel there will be sleep deprivation on the weekend if you are planning to stay up late. Maybe, if this is the case, you will want to start going to bed a half an hour to an hour earlier from now on so that it helps the immunity and prevents infection.

2. Avoid junk food. Needless to say, it is very tempting but it may be a good idea to replace junk food snacks with good and healthy foods, thereby preventing bronchospasm, mucus formation, and nighttime symptoms of bronchial asthma. Cookies, pasties, etc., have refined sugar, which cause mucus formation and bronchospasm. Making sure a high-fiber diet is continued during the holiday season so there are normal bowel movements every day in the morning helps to prevent bronchospasm. If one is not getting a high-fiber diet regularly, he/she may help with starting one. Eating lots of fruits and vegetables helps. Apples, pears, grapes, strawberries, carrots, cabbage, and spinach to name a few, are good sources of healthy fiber. Understanding the basics of the diet and what needs to be avoided on a regular basis may help prevent exacerbation of asthma. Avoid dairy products such as cold food, ice cream (produces bronchospasm and mucus), bananas (increases sputum production and chest congestion), cold water or ice water or ice drinks also increase bronchospasm and replace them with room temperature water or drinks. Just like cold weather makes asthma worse, so do cold liquids and drinks which create winter inside the body. It slows stomach digestion, producing bronchospasm. We have seen in our practice that stopping this has decreased the need of a rescue inhaler by more than 50% in about 6 weeks in many asthma patients and in many after only a few months. It may help if one is looking for ideas that help to decrease the need for rescue inhaler use.

3. Compliance with the treatment of bronchial asthma. Continue the regular inhalers, nebulizers and other medication as prescribed by your health care professional. Understand the correct technique of the inhaler or nebulizer. Get familiar with the medication and its normal dose, the maximum dose that is allowed and its common side effects. If you feel that you are getting any of the side effects, let your doctor know about it. Make sure you rinse your mouth after the use of the inhaler or nebulizer to prevent oral thrush.

Use the peak flow meter to check the asthma symptoms and keep a log of it. If one is a smoker than smoking cessation is the key to improve health, otherwise bronchial asthma or COPD will not get better and with time it will get worse. Inhalers or medication will not work with ongoing smoking. A person can end up with respiratory failure and be on a ventilator with ongoing smoking if asthma or COPD exacerbation cannot be controlled with nebulizers, steroids and antibiotics. Smoking cessation is key.

4. Exercise. Regular exercise helps to prevent the bronchospasm and chest congestion. In patients with exercise-induced bronchospasm, they may need to take the inhaler prior to work out. This is equally true for the patient with chronic obstructive pulmonary disease as well as bronchial asthma patients.

5. Yoga and Pranayama. Pranayama are the breathing exercises of yoga. One may learn Pranayama and many other exercises of yoga to reduce stress from a local yoga instructor, which may help prevent bronchospasm, chest congestion, and nighttime wheezing. Yoga exercise is very different from a regular work out or aerobic exercise. After yoga, one may feel more relaxed and calm. Both exercises have their own merits and limitations and based on one's personality one may favor one over the other. The goal is to do one or both than none at all.

In our practice, we have patients with severe persistent bronchial asthma symptoms on round-the-clock inhalers and nebulizers with multiple modalities of treatment and exercise. Yoga has shown such improvement in some patients that they do not need a need of inhalers or nebulizers. The point here is to say that yoga exercise and/or other regular or aerobic exercises do help if one does them regularly and helps the asthma symptoms as well as overall health when done regularly along with medical treatment.

Adenoids Surgery Not Always Effective

There was a time in the United States when doctors would remove tonsils and adenoids from young children simply as a matter of course so that they did not cause problems later on. Then, in the late 1960s and early 1970s, as awareness of unnecessary surgeries grew and the medical profession came under increasing scrutiny, these surgeries tapered off and became all but unheard of except in the most extreme circumstances and after proving substantial medical necessity.

Recently, however, the incidence of both tonsillectomies and surgery for the removal of adenoids has been on the rise yet again. Doctors are suggesting to parents with children as young as three that their adenoids need to come out. The reasons given for surgery of the adenoids are usually because of sleep apnea or breathing difficulties. According to doctors, if the adenoid becomes too large it will partially block a child's breathing during sleep. Doctors will also remove adenoids because of frequent ear infections.

One thing, however, that many surgeons do not tell parents is that all of the adenoids cannot be removed with the surgery. Adenoid tissue will still remain, and it is not uncommon for the adenoid to regenerate and "grow back." When this occurs, symptoms also return.

Every surgery has risks. The most common risks involve complications with or reactions to anesthesia. Other risks involve excessive bleeding during the surgery or clotting issues following the surgery. And, of course, with any surgery the risk of infection is always present. When faced with a surgery, most patients weigh the benefits received from the surgery against the likelihood and severity of possible risks. And many rely upon what doctors tell them to make a decision.

The removal of adenoids is questionable, at best, and it is doubtful as to whether the benefits outweigh the risks of surgery, especially for a small child. Additionally, surgery should only be seen as a last course of action when all other options have been tried and have failed. Furthermore, every parent should remember that though breathing difficulties can be troubling and make a parent feel as though they should do "something," the tissues that make up the adenoids will begin to regress in size during adolescence. Some of the reasons why doctors suggest that adenoids be removed such as recurrent ear infections also abate with age.

Rather than subjecting a young child to the trauma and possible risks of unnecessary surgery, parents might want to consider investigating treatments for adenoids without surgery. Surgery to remove the adenoids would seem a drastic step when so many other options are available.

When you improve breathing, you improve your total health and reduce or eliminate the need for adenoids surgery.

The test will help you determine whether you hyperventilate or not, and if so to what degree, and how that may be affecting the quality of your sleep, as well as recommendations for improvement.
