Hi, need to submit a 1750 words paper on the topic Pathophysiology of Presenting Features.

Further West (2011) states that the Dyspnea on exertion is due to the failure of the ventricular of the left output rising during and also results in an increase of pressure on the Pulmonary vein. In the case of one having cardiac asthma, the pulmonary congestion is associated with bronchospasm that is normally precipitated by the action of edema fluid in the walls of bronchi to the external receptors. John has the above-named symptoms for cardiac asthma, but a further examination of the presented features may provide other possibilities.

Moreover, the gain of weight and increased breathing rate may indicate the possibility of blood pressure issues. The evidence of occasional coughing increases the chances of Bronchial Asthma. Research has shown that there is an overlap between chronic obstructive pulmonary disease and asthma. Rosto (2009) predicts the typical symptoms for asthma to include wheezes, shortness of breath, tightness of the chest, and coughing. The specific features common for asthma in adults may be identified if the above-mentioned symptoms are worse at night and early in the morning, occur during exercise, cold air, and allergen exposure or aspirin.

All these symptoms can be identified in the case of John. On the other hand, coughing up blood especially from the respiratory tract is referred to as hemoptysis (Leigh & Marley, 2013). Among the various other causes of hemoptysis that are relevant to John is that it may be the origin of bronchitis. In this regard, the main features of the hemoptysis include a productive cough for three months of the year for two successive years in smokers. Furthermore, the saliva of patients with asthma may at times appear pink when it contains large amounts of a type of blood cells called eosinophils.
