Asthma: A Respiratory Condition Which Can Be Controlled

Asthma is a problem that is prevalent all over the world and has affected people of all ages and almost every walk of life. It is a condition which affects the respiratory system. In this condition the respiratory airways which are responsible for the passage of air in and out of the lungs are narrowed. This results in wheezing, shortness of breath and coughing.

The narrowing of the airways is most times temporary, however sometimes Asthma can be fatal. Bronchial asthma is a common cause of death in many countries all over the world. This condition mainly refers to the inflammation of the respiratory airways.

Asthma is mainly triggered or activated by a number of agents which are also referred to as allergens. However, this may vary from person to person depending on the effect that each trigger has on the lung. These triggers or agents are categorised into two namely allergens which are specific and non allergens which are non specific in nature.

The common allergens are the seasonal pollens, molds, mites, dust, certain foods like fish, milk, soy and peanuts, agents like latex and food additives and preservatives. Another important fact about Asthma is that most people suffering from Asthma also suffer from allergies. The non allergens are mainly irritants like respiratory infections, drugs like non steroidal anti-inflammatory drugs, tobacco smoke, perfumes, deodorants and paints, certain outdoor factors like diesel fumes and smog and certain hormonal factors.

This condition can be taken care of by taking proper and adequate medication. It is important to keep away from allergens and irritants so that the incidences of an asthmatic attack are reduced to a great deal. However, one should also note and keep in mind that the medication should be taken regularly and kept handy at all times to avert an asthmatic attack.

Types and Uses of Nebulizers for Various Respiratory Symptoms

An increase in the number of people with respiratory distress is going up proportionally with the rising levels of pollution across the globe. Problem in the respiratory system, which most people term as problem while breathing, has become common among all of the age groups and ethnicities. However, no one can survive without oxygen for any longer than a few moments and it is essential to relieve people suffering from respiratory distress to prevent long-term damages. A number of techniques and equipment are available for helping people combat respiratory distresses. Among these equipments, the nebulizer is one of the most popular devices for combating respiratory troubles.

The nebulizers are extremely popular as devices for providing essential medications and oxygen to people suffering from asthma, or some other respiratory disorders in the form of a mist. The nebulizers function with the help of a compressor, which converts liquid medication into mist for the inhalation of people suffering from any of the several congestive respiratory syndromes. Patients with congested airways can inhale the essential medications in the mist form to a much greater degree compared to their original form. This device is extremely effective in providing relief to children, senior people, and patients with severe cases of asthma who might be unable to inhale through a standard inhaler.

The nebulizers that are available on the market come in primarily two different types. The first of these two types is the jet nebulizer, which uses compressed air in the form of aerosols to deliver various medications. They contain a compressor that then pushes in a stream of minute droplets in jet motion inside the airway of the users. These are the nebulizers of choice for the medications consisting of drug particles in a liquid suspension. Another name for jet nebulizers is the atomizer and they are extremely common in the hospital setting. The pressure generated by the compressor, expressed pound per square inch, was important for the older models, but they have lost their relevance with the latest ones.

The other major type of nebulizers is the ultrasonic nebulizer, which uses ultrasonic sound waves to create a fine mist containing medications. They do not use a compressor but a crystal, which produces a sound wave with enough energy to transform liquid medication into a fine mist that is perfect for easy inhalation. They are suitable for use at homes and are available in portable form for more convenient uses. However, they are not suitable for use with certain medications because of the high-frequency sound waves they use to convert any medication in liquid state into fine mist. This can lead to changes in the molecular structure of the drug that can render it useless or with a number of side effects.

These days the availability of portable nebulizers has made it possible for people suffering from chronic congestive respiratory syndromes to benefit from their use. These devices run on electricity and their form makes them perfect for tabletop use. Therefore, people in both household and hospital settings can benefit significantly from the use of nebulizers to ease their respiratory distresses.

Various Types of Antibacterial Drugs and Its Uses

Antibacterial drugs are used for the treatment of various types of bacterial infections in humans, animals and plants. There are a variety of antibiotic drugs which are used to treat various types of diseases. Each drug helps to treat a particular type of bacterial infection.

These drugs are powerful medicines which are used to inhibit the growth of bacteria that causes infections in the body. It helps the body to fight the disease causing bacteria. These drugs have been in use since the early 1930s. Most of these drugs are prescribed for bacterial infections and not viral infections such as common cold, flu and mumps. Penicillin was the first antibiotic that was discovered by Alexander Fleming. Today there are more than hundreds of different types of antibacterial drugs available all around the world.

Different Types of Antibacterial Drugs

Antibiotics are mainly classified into two varieties, which include the broad spectrum and the narrow spectrum, on the basis of its action on a particular type of bacteria. Drugs which are used to treat infections caused by different types of bacteria are classified under the category of broad spectrum. Narrow spectrum antibiotics are used to treat specific type of bacteria. Some of the most common varieties of antibacterial drugs include the following.

Tetracycline: This particular antibiotic is mainly used to treat ear infections, urinary and respiratory tract infections. Tetracycline is a broad spectrum antibiotic and it often includes minocycline and doxycycline. However, the internal consumption of tetracycline can cause certain side effects such as gastric problems and indigestion. It can also lead to stomach problems. Tetracycline should not be consumed by people suffering from liver disorders.

Penicillin: One of the earliest antibiotics discovered by mankind includes penicillin. It is used to treat a wide number of diseases. This antibiotic destroys the cell walls of the bacteria in its stage of reproduction. Penicillin includes various other antibiotic agents such as oxacillin, ampicillin, nafcillin, penicillin V and G. This antibiotic is mainly used to treat eye, ear, skin and respiratory tract infections. Penicillin is often prescribed in combination with other antibiotics as it can cause mild allergies in some people.

Sulfonamides: This antibacterial drug is quite effective in treating kidney infections. It is quite similar to penicillin in its ability to fight bacterial infections.

Aminoglycosides: Another variety of antibiotic is the Aminoglycosides which includes neomycin, gentamicin and streptomycin. It is mainly used to treat pneumonia and other such diseases.

Polypeptides: This particular variety of antibacterial drug is mainly used to treat skin infections. As it is quite toxic, it is used for external applications only.

Macrolides: This antibiotic includes erythromycin, azithromycin and clarithromycin. It is mainly used to treat respiratory tract infections and other such ailments. The drug has mild side effects such as nausea, diarrhea and stomach discomforts. It is however not prescribed to pregnant women and elderly persons.

Antibacterial drugs are prescribed on the basis of the infections. In certain cases, blood specimens are cultured to identify the type of bacteria that has led to infections. Doctors then prescribe the antibiotic drugs accordingly.
