Pathogenesis of Asthma
Asthma (also known as respiratory illness) is a persistent or long standing disease that influence and attacks the airways of the lungs. When we breathe, so throughout our normal breathing the bands or strings of muscles that surrounds or are adjacent to the airways of the lungs are relaxed and de-stressed which causes the air to pass freely. When we talk about asthma episode or commonly known as asthma attack, what causes the change in the airways due to which air is not able to pass freely and due to which the person suffers from asthma attack. Following are the three main reasons which cause the blockage of air from passing freely throughout the airways of the lungs:
|Asthma – a rare but common disease|
- The first main reason is known as “Bronchospasm”. It is a medical term which means that due to narrowing of airways which is caused by tightening of bands or strings of muscles which surround the airways of the lungs causes the blockage of air and stops the air from passing freely throughout the lungs which will cause suffocation resulting in asthma attack.
- The second reason which can be listed is the production of thicker mucus than normal. Mucus is a substance which is produced by the cells of the airways and if that mucus is thicker than the normal one it can also cause blockage of air and will stop the air from passing freely resulting on asthma attack.
- Another reason that can be listed is the inflammation or the swelling of the lining of airways of the lungs. If the lining is swollen if will also stop the air from passing freely throughout the airways which will cause suffocation and eventually resulting in asthma episode or attack.
These are the three main causes of asthma attack. Bronchospasm, thicker mucus production or inflammation or swollen lining of airways can cause coughing, wheezing (breathing noisily) or difficulty in breathing.
Described above were the few main causes of asthma attack but when we discuss or talk about the age group or what persons can be affected by this asthma disease, so the answer is simple. According to a research it is shown that approximately around 21 to 22 million USA citizens are affected by or are suffering from asthma and among these 22 million Americans, 5 to 6 million are children who are under the age of 18. Adding to the list are those people also who have a family background or the people who have relatives or family members who are suffering from asthma can have a high risk of developing this disease. Also the persons who are more exposed or are more prone to the tobacco smoke or are suffering from some sort of allergies can also have increased rate of developing asthma disease. But having said that, any person of any age group or at any age can develop this disease and can suffer from asthma. Hence there is no particular or defined age of this disease; some people can face this disease for all of their life, while some may develop this disease as adults.
Albuterol: What You Should Know
Albuterol is used to remove constriction from the airways, thereby making it easier for a person to breathe. It is used as a short term reliever for people living with asthma and can be used by children of at least age four as well as adults. It is important to note that albuterol should be carried around at all times, as asthma can be a life threatening disease. This inhaler might not work for really severe cases, and you need to let your doctor know if it doesn’t work, or you have to use it a lot for it to have an effect. Using albuterol as a short term reliever like any other drug can be overdosed on. This is why it is advisable to take not more than 10 puffs, at 60 second intervals at a go.
Albuterol cannot be taken by everybody, due to the possibility of side effects. Telling your GP pertinent information will enable him makes a properly informed decision as to whether it’s safe to be on the drug or not. Things like heart problems, heart failure, and high blood pressure should not be left out when giving the doctor your health information. Others such as: potassium levels, epilepsy, seizures, diabetes and thyroid problems should also be included. The effect of this drug on pregnant women hasn’t yet been confirmed, so it is necessary to let the doctor know, so he could make an informed decision. Breast feeding mothers should also indicate this to their doctors as it is not yet known whether this could cause a detrimental effect.
The drug should always be taken as per prescription, no more and no less. This is to prevent overdose and other related problems. The instructions are always written in the instruction manual, and have a specific guide as to how the medicine should be taken, for maximum effect. This drug can be used to treat exercise related asthma attacks; 2 inhalations 15 minutes before exercising are enough to do the trick. Albuterol is a quick reliever, so it only lasts for about six hours maximum. Use a spacer, if necessary and ensure to get a new inhaler before the old one completely finishes. Do not put the canister in direct contact with a heat source even when empty, to prevent it from exploding. Keep the canister away from hot and humid areas.
Albuterol can also be used as preventive measures, to be taken at certain intervals during the day in does. Since the inhaler can only last for about four to six hours, once in this timeframe is the required dosage. If the dosage has been missed, and it isn’t time or even close to the time for the new dosage it is required that you take your missed dosage. Do not take two successive dosages at once, to prevent an overdose. If you do overdose, call an emergency service immediately. Symptoms for overdose can include nausea and fainting amongst others.
