Jun 24, 2023 · Asthma is primarily involved in the bronchial tree, with its primary job to distribute air throughout the lungs until reaching the alveolar sacs. The bronchi stem from the end of the trachea, which divides into left and right bronchi.
Asthma is a common chronic disorder of the airways that involves a complex interaction of airflow obstruction, bronchial hyperresponsiveness and an underlying inflammation. This interaction can be highly variable among patients and within patients over time.
Apr 6, 2024 · Identify and avoid asthma triggers. A number of outdoor allergens and irritants — ranging from pollen and mold to cold air and air pollution — can trigger asthma attacks. Find out what causes or worsens your asthma, and take steps to avoid those triggers. Monitor your breathing.
Jun 14, 2024 · The pathophysiology of asthma refers to the changes that occur in the airways and lungs that lead to asthma symptoms. Understanding the pathophysiology can help with...
Jul 7, 2015 · Understanding asthma pathophysiology helps you understand how the condition is diagnosed and treated. Our knowledge of asthma pathogenesis has changed dramatically in the last 25 years, as researchers have found various asthma phenotypes.
In this chapter, we will briefly explore some major theories of asthma pathogenesis, both new and old. We will also explore how understanding the pathophysiology of asthma can help us to understand the symptoms and presentation of asthma, as well as the best strategies for diagnosing this disease.
Asthma is a disease of diffuse airway inflammation caused by a variety of triggering stimuli resulting in partially or completely reversible bronchoconstriction. Symptoms and signs include dyspnea, chest tightness, cough, and wheezing. The diagnosis is based on history, physical examination, and pulmonary function tests.
Pathophysiology of Asthma, Figure A shows the location of the lungs and airways in the body. Figure B shows a cross-section of a normal airway. Figure C shows a cross-section of an airway during asthma symptoms. Specialty: Pulmonology
May 6, 2024 · Key facts. Asthma is a major noncommunicable disease (NCD), affecting both children and adults, and is the most common chronic disease among children. Inflammation and narrowing of the small airways in the lungs cause asthma symptoms, which can be any combination of cough, wheeze, shortness of breath and chest tightness.
Pathophysiology. Asthma is usually mediated by immunoglobulin E (IgE) and precipitated by an allergic response to an allergen. IgE is formed in response to exposure to allergens such as pollen or animal dander [4] Sensitisation occurs at first exposure, which produces allergen-specific IgE antibodies that attach to the surface of mast cells.
