The average annual asthma prevalence is higher in children 9. The prevalence of asthma is higher in black persons than white persons, and the ethnicity most affected is the Puerto Rican population. Asthma prevalence increases with each successive lower poverty level group. There are interesting relationships between asthma and certain otolatyngologic diseases. The impact of asthma on both morbidity and mortality is particularly noteworthy . The Global Asthma Report gives an account that Asthma kills around people every day and affects as manyas million people and prevalence is rising.
On average, 3 people a day die from asthma. Although the UK still has some of the highest asthma prevalence rates in Europe, its prevalence is thought to have plateaued since the late s. In Scotland, approximately , 1 in 14 people are currently receiving treatment for asthma: 72, children and , adults. Asthma has many possible causes as the exact mechanism of onset is still unknown. This is due to asthma not being defined as a single disease, but a variety of multiple diseases with similar clinical features, resulting from different genetic and environmental causes  mainly developing at an early age, The complex interplay between hereditary and environmental factors which are occurring at this critical time in development, lead to the onset of the disease  .
Patients who are atopic have a genetic predisposition for developing the disease due to a hypersensitivity of the airways to environmental triggers.

An allergic reaction to antigens that normally do not cause a response, predisposes to asthma onset demonstrating the genetic component of the disease. Asthmatics can commonly suffer from other allergies including food, drug and skin allergies .
Sufferers are chronically-exposed to substances when inhaled lead to an allergic response in the airways . The following risk factors increase possibility of disease development; Hereditary. Environmental . Asthma trigger an asthma attack. Some causes of the manifestation of asthma may also trigger an attack. In asthma, airway constriction is caused by a combination of bronchial constriction bronchoconstriction and bronchial inflammation.
This leads to chronic lung pathology in which the bronchial airways are prone to narrowing, causing episodes of wheezing, chest tightness, coughing and breathlessness SOB that range in severity from mild to potentially life threatening . As a result, constriction of smooth muscle in the walls of the airway and excessive release of mucus into the area causes airway narrowing and ultimately reduces the amount of air circulating in and out of the lungs . Due to these differences in airway flow rate, the lungs become hyperinflated.
Therefore, although these patients have hypoxia, the low levels of oxygen low PaO 2 trigger hyperventilation and therefore decrease PaCO 2 to prevent hypercapnia and the retention of carbon dioxide. During the first stages of an acute episode, alveolar hyperventilation can result in respiratory alkalosis. Bronchoconstriction causes an audible wheeze and subsequent cough.
Chest tightness can be felt and a shortness of breath dyspnoea from a constriction of the bronchial walls. Sputum is produced due an inflammatory response in the airways  adding to the difficulty of breathing. Asthma is an obstructive lung disease.

Narrowing of the airways bronchospasm due to constriction of the bronchial muscles in the wall, lead to decreased air flow and difficulty with breathing. Bronchospasm causes decreased peak expiratory flow rate, which in turn leads to decreased PaO 2 and increased PaCO 2 of the blood. Heart rate increases to compensate for a lack of oxygen being transported in the blood. To increase oxygen during inspiration, hyperventilation will occur in the patient.
However work of breathing will be increased due to the narrowed bronchi which make it more difficult to breathe . When these signs and symptoms presents, a person should be aware and are advice to consult with your general practitioner as soon as possible. There are a few risk factors associated with asthma that can lead to the onset of asthma, an attack or other respiratory symptoms. Many substances can trigger allergies and the same applies to asthma. Common allergens that triggers asthma are pollen, mold, dust mites and pet dander.
Other irritants are smoke, pollution fumes, sprays and cleaning chemicals. Asthma symptoms can therefore be reduced by avoiding exposure to known respiratory irritants and allergens.
The patient is initially asked to explain their various symptoms, including their description, frequency, duration and aggravating factors. Substance exposure may have also lead to the onset of asthmatic symptoms, in which case exposure to tobacco smoke, chemical fumes, dust or other airborne irritants is determined. If the patient has a family history of asthma or allergies, they are more likely to also suffer from asthmatic symptoms. Med J Aust. However, several studies found that acute hyperventilation with CO2 enriched air also results in asthma attacks.
Therefore, as some doctors claimed, low aCO2 could not be considered as a single cause of asthma. Is this opinion correct? A: Before being tested with CO2 enriched air in laboratories, typical asthmatics had many hundreds of times the following course of events. On the background of chronic hyperventilation all known studies reported the presence of hyperventilation for initial stages of asthma , asthmatics experienced the influence of some other triggering factors like exercise, overeating, oversleeping, allergies, etc. Sometimes, this airway obstruction could be due to, for example, excessive mucus production or inflammation.
That could result in anxiety and panic causing acute hyperventilation. In all cases, these asthmatics breathed normal air with about 0. Thus, before the attacks, the following physiological changes were repeated many hundred times: abnormally hard work of the respiratory muscles, increased air flow through the respiratory tract, increased amplitude of pressure variations in internal organs, etc.
All these changes, before the attacks, were sensed many hundred times by the millions of nerve cells of the nerve system.

Finally, further lowered aCO2 and some other factors produced additional bronchoconstriction and the attacks. Now, exactly the same asthmatics arrive in the laboratories, where they perform the same acute hyperventilation, which is accompanied by all these described additional features again sensed by the millions of nervous cells with one difference, the inspired air is CO2-rich.
Such air has never been experienced by these asthmatics before, but the whole nervous system learned that such a situation causes bronchoconstriction. What would be the result now? The result due to the changed stimulus would be defined by how much of the previous stimulus is left.

Low carbon dioxide already created many chronic abnormal changes. Finally, some other triggers which cause the attacks can also be at work when the person deliberately hyperventilates, even with a temporary increase in carbon dioxide stores. It was not a sudden drop or increase in carbon dioxide stores that causes or prevents asthma attacks, but those chronic changes which affect every cell of the respiratory tract in asthmatics. But assuming that the human nervous system is incapable of learning from the previous experiences repeated hundreds of times and that all these events sensed and recorded by the nervous system did not produce habituation and conditioning, one can assert that low carbon dioxide is not the cause of asthma.
Therefore, even in conditions of artificially increased aCO2, the influence of so many areas of the nervous system should be more powerful, than that of the breathing center. Meanwhile, if such tests with CO2-rich air were repeated many times, the effect of gradual relearning can be observed and acute hyperventilation with CO2-rich air would not cause bronchoconstriction and the attacks.

Moreover, physiological studies found the confirmations of this psychological effect based on the physiology of the nerve cells. It is known that, for example, some breathing maneuvers chapter 2 , e. All previous life, movements of respiratory muscles resulted in the new oxygenated air coming into the lungs. Normally, the nervous system learned millions of times, that such respiratory movements are signs of new fresh air flow. It is now a clear fact, which has been confirmed by all published studies, that development and first stages of asthma are always accompanied by hyperventilation.
