Asthma is a common chronic disease that is characterized by an inflammatory process of the large and small airways causing reversible airflow obstruction and airway hyperresponsiveness. In many countries, the prevalence of asthma has increased in recent decades. An analysis of asthma mortality rates in Western countries such as the United States, Canada, New Zealand, France, Denmark, and Germany has revealed a distinct rise in rates during the 20-year period prior to 1990. To treat asthma you should buy ventolin inhaler.
This trend was less apparent in other countries. An increased prevalence of asthma cannot be a primary contributor to increased mortality rates since the rise in the latter was disproportionately greater than that of the former. In the last decade, though, the stabilization of mortality, and even a decrease in mortality, from asthma has been reported. Asthma mortality is associated with multiple factors, including delay in care, poor compliance, lack of access to health care, theophylline toxicity, and overuse of (3-agonist medications. Speculation about the recent decline in asthma deaths has pointed to the more judicious use of prophylactic treatment, particularly inhaled steroids, as a possible factor. Studies also have shown that race and socioeconomic status may influence the outcome of an asthma attacks.” Efficient treatment for severe asthma attacks exists, requires hospitalization, and may include mechanical ventilation. Hospital admission rates for asthma are high and have increased in the last few decades. However, some patients die before they can receive medical care.> The true proportion of deaths occurring outside the hospital and its association with genetic, environmental, or sociologic factors is not clear.
