Pathophysiology of Asthma - A Brief Overview
Asthma is now considered to be more of an inflammatory response disease having two major forms of breathlessness. It is usually airway wall inflammation and airway wall constriction that arises due to the release inflammatory response chemical signals that are the major causes of asthma. The best way of understanding asthma is with some knowledge of asthma pathophysiology.
Prehospital Pathophysiology is a new monthly column that provides an opportunity for EMS providers of all levels to either refresh their knowledge related to the etiology of a certain disease or expand their knowledge base regarding common and not-so-common disease processes
Although asthma is defined in terms of reversibility of airflow obstruction, as the disease becomes more severe and chronic, it adopts different characteristics, including a degree of fixed airflow obstruction and corticosteroid refractoriness.
Many inflammatory cells participate in the inflammatory process in asthma and mediate a complex mixture of mediators. Cytokines are of particular importance as mediators of chronic inflammation and the means by which cytokines amplify and perpetuate the inflammatory process is now emerging
Asthma is best described as a chronic disease that involves inflammation of the pulmonary airways and bronchial hyperresponsiveness that results in the clinical expression of a lower airway obstruction that usually is reversible. Physiologically, bronchial hyperresponsiveness is documented by decreased bronchial airflow after bronchoprovocation with methacholine or histamine
Some forms of alternative asthma medicine can be effective in asthma treatment, it is important to consider that it does not work with everyone. The level of asthma is an important factor in determining whether or not alternative asthma medicine will work. More severe cases of asthma may have to be handled with doctor prescribed methods
By measuring peripheral airway resistance in humans, it is known that mild asymptomatic subjects have a significant increase in peripheral airway resistance in spite of near normal lung function. It is possible to examine the alveolar region with the use of transbronchial biopsies.
