COPD - Case Study Example The chances of having COPD grow the more one smokes and the longer one has been smoking. This is because smoking inflames and irritates the lungs, which consequences in damaging. Over several years, the irritation steers to long-lasting variations in the lung. The partitions of the air-passage thicken and more secretion is generated. Injury to the subtle walls of the alveoli in the lungs results to emphysema and causes the lungs to lose their regular elasticity. The minor alveoli become damaged and contracted (Ellen & Kirkhorn, 2015).  These variations results in the symptoms of coughing, breathing difficulty and phlegm related to COPD. A patient named R.S. comprised of pathological variations in four different partitions of the lungs (pulmonary vasculature, lung parenchyma, peripheral airways and central airways), which are patchily available in R.S. with the COPD. Tobacco smoking is the main risk factor for R.S. patient with COPD, however, other inhaled toxic particles and gases may contribute. Therefore, treating tobacco use and dependence should be regarded as a primary and a speciï ¬ c intervention for R.S. condition. His smoking should be evaluated routinely whenever the patient avails himself to a healthcare facility and should be provided with the best opportunity to treat his condition. This results in an inï ¬â€šammatory reaction in the lungs, which is blown up in this particular patient who is a smoker and drives to the distinguishing pathological destruction of the lungs of the patient (Ellen & Kirkhorn, 2015). Furthermore to lung inï ¬â€šammation, antiproteinases and an imbalance of proteinases in the lungs and oxidative stress are also essential in the pathogenesis of the patient. The variant pathogenic mechanisms generate the pathological variation which, subsequently, develop the following physiological defects in R.S patient: cilliary dysfunction and mucous hypersecretion; hyperinï ¬â€šation and airï ¬â€šow limitation; gas

Comparison of Models - Research Paper Example It is noteworthy that the major differences between psychological and multicausal models of addiction are based on their varied beliefs on the causes of addiction. Psychological model of addiction, which derives its understanding from a number psychological models key among them being psychoanalytic theory developed by Sigmund Freud, the behavioural and cognitive theories of psychotherapy. Psychological model asserts that addiction is motivated by psychological distress. In other words, this model of addiction is based on the belief that addiction is because of repression and unconscious mental processes (Raymond, 1998). Addiction in this sense is just a secondary problem as psychological problems takes precedence. This means that addiction is only a coping mechanism as at seeks to create an illusion of comfort away from internal conflicts in an individual’s life. For instance, Sigmund view all forms of addiction as a substitute for primitive sexual urges, which brings about an internal conflict and intensified guilt that is reengineered by an addiction cycle. Psychological model emphasizes on the intrinsic drives especially cognitive which motivate people to develop a cycle of drug use and dependence (Raymond, 1998). For instance, individuals are seen to develop a tendency of using drugs as form of self-medication to internal conflicts brought about by dysfunctional thought patterns. In other words, addiction personality is real and it is experienced constantly owing to the fact that it is used as a coping mechanism against stirred up emotions, traumatic experiences, sexual issues, fears, negative relationships, feeling of powerlessness. A number of things that individuals try to self medicate have been categorised into four groups and they include difficulty in self-care, the expression of emotions, troubled relationships and low
