A Short Note On Asthma And Its Effects On His Admission And The Care
Mr. Harding has a number of ‘pre-morbid’ chronic conditions that may be impacting on his admission and the care you will need to provide. Choose two (2) of Mr. Harding’s chronic diseases, explain the pathophysiology. What organs are affected by each disorder? (20 marks/10 per disorder)
Asthma is a chronic syndrome related to the inflamed airways of the lungs (Rogers 2010). This is due to the constriction of the airways from an exaggerated response to triggers that lead to “episodes of wheezing, chest tightness, dyspnea and coughing” (Rogers 2010). Asthma can start at any age. Atopic asthma, in most cases starts in childhood, and is often related to an inherited predisposition to identifiable allergens, for example dust mites, pollen and grass (Rogers 2010). Being exposed to these allergens leads to the release of large amounts of Immunoglobin E (IgE) from B lymphocytes. During inflammation, IgE attaches to the cells involved in the process and stimulate the release of inflammatory mediators, such as histamine, that lead to bronchoconstriction and airway inflammation (Kim & Mazza 2011).
Non-atopic asthma are factors that are not linked to those of atopic disease (Kaufman 2011). This includes asthma in adults which develop in response to factors such as physical activity, climate conditions, aspirin and viral infections.
The organs of the lower respiratory tract- trachea, bronchi and bronchioles are all affected by asthma.…
