These episodes of shortness of breath are called “attacks”. The frequency and severity of each attack of breathlessness varies from person to person. World Health Organization (WHO) estimates that worldwide 235 million people suffer from asthma. This chronic disease is very common in children. Although not fatal, 80% of asthma-related deaths occur in low-income countries. Asthma is underdiagnosed and undertreated, creating a financial burden on families and restriction of physical activity of the patient. This restriction is sometimes for life. Asthma can not be cured completely. But it can be controlled. The most important risk factors that trigger asthma are a mixture of hereditary reasons and environmental triggers. Snuff smoke, air pollutants, irritating chemicals and related environmental factors are known to trigger asthma attacks.
The best way to prevent asthma attacks is to be careful with environmental triggers and other safety and stay away from them. But what do you do when the attack occurred? Steroids, anti-inflammatory drugs and bronchodilators relax muscles to constrict the air flow. Inhalers are devices commonly used to administer asthma medication directly to the lungs. Overall it is a handheld device. MDI can be metered dose (MDI) and dry powder inhalers (DPI). DPI requires the patient to breathe deeply and rapidly. Because of this IPR are difficult to use during asthma attacks when it is difficult to breathe normally. Some patients, especially children who experience difficulty using MDI and DPI.
Then, your doctor may prescribe a respirator. These machines transform the treatment of asthma liquid to a vapor. This makes it very easy to inhale. In general, a nozzle is used in this process. But medicine pushed in this direction may take longer to take effect. But its main advantage is the ease of use as a patient can breathe quite normally and effortless to use. A respirator may or may not handheld. They can also be portable to the drug in the road. They are most effective when the patient breathes normally quite. Deep rapid breathing reduces the impact. So for children, it is best done when they sleep. Sometimes, the choice of MDI or difficult breathing machine. Tickets are important doctor. However, some tests say it is best for each patient.
