Respiratory sounds can also define as breath sounds or lung sounds. It is generated through the turbulence of airflow in our respiratory tract. The air breath in and out are transmitted through air, liquid and solid and to the chest wall. Each properties of substance that the air attenuated lead to different degree and intensity of breath sounds (Jones, 1995a).
Breath sounds can divided into three type, normal, abnormal and diminished (Alexandra Hough, 2001). Breath sound is useful in diagnosing or monitoring respiratory disease and airway abnormalities, such as asthma, Chronic Obstructive Pulmonary disease (COPD), pneumonia and so on. It can be auscultate across chest wall with a stethoscope. A physician can auscultate breath sounds to detect …show more content…
Auscultation with a stethoscope need a professionally well-trained physician to recognise the abnormalities accurately. Moreover, Lung auscultation is a non-objective method, which depends on the experience, skill and sounds perception of the physician. To overcome the defect, researcher started to exploit computer-based lung sounds analysis system. Digital recording and analysis becomes the only reliable and quantitative way for diagnose the lung sounds. Studies on computer -based breath sounds started in the literature since 1980s. Nowadays there is advancement about signal processing to detect the abnormalities and disease using computer-based breath sound auscultation.
The major problem faced in studies on computerised- based lung sounds analysis is to relate the breath sounds to the disease correctly which has not been study by researcher before. Every respiratory sounds has each properties and science and technology has made breath sounds simple to improve the classification of pulmonary diseases. The pulmonary diseases have their dominant frequency range, which can detected by apply signal processing techniques (Palaniappan.R et al.

His past medical history includes emphysema and chronic bronchitis. He used to smoke but has stopped since a year ago for economical reasons as well as it is also bad for his asthma. His bowel movements have also been irregular since his admission. He also reported that he is feeling depressed and fearful about the future. Further examination revealed that he has crackles in his left lower lobe with diffuse expiratory wheezing throughout his chest. Chest percussion also revealed his left lower lobe to be dull.

Mini Case Study on Bronchial Asthma

...Cotabato Regional and Medical Center opened the door of opportunity to experience things that broadened our knowledge and enhanced our skills. We were exposed to different cases of various clients. We became accustomed with the routines in the hospital and interacting with our patients, even with their watchers. We encountered some difficulties and struggles, yet that didn’t hinder us in giving our best to do our job. That exposure gave us an opportunity to handle different cases. With all those we’ve encountered, we chose one to be the subject of our case study. We are presenting to you Bronchial Asthma which is the case of our patient at Medicine Ward Room C whom we will call Mr. Theodore for the purpose of confidentiality. Bronchial asthma is a disease caused by increased responsiveness of the tracheobronchial tree to various stimuli. The result is paroxysmal constriction of the bronchial airways. Bronchial asthma is the more correct name for the common form of asthma. The term 'bronchial' is used to differentiate it from 'cardiac' asthma, which is a separate condition that is caused by heart failure. Although the two types of asthma have similar symptoms, including wheezing (a whistling sound in the chest) and shortness of breath, they have quite different causes. Bronchial asthma is a disease of the lungs in which an obstructive ventilation disturbance of the respiratory passages evokes a feeling of shortness of breath. The cause is a sharply elevated resistance to airflow...

Health Assessment Case Study Asthma

...Health Assessment Case Study Introduction The focus of this case study is to examine further focused assessments that should be undertaken after Mr S's initial presentation of acute exacerbation of asthma. Reasoning for recommended focused assessments will be discussed with consideration of Mr S's presentation of symptoms, history, pathophysiology and risk factors for asthma exacerbation. Research on current asthma assessment protocols will guide recommendations, and assessment parameters will be described. Follow up care and self-management options for Mr S will also be explored. Asthma Asthma is a chronic inflammatory disease of the lungs. It is characterised by airflow obstruction and lung inflammation (Johnson, 2010). Asthma symptoms include wheezing, chest tightness, shortness of breath and cough (Johnson, 2010). Potential triggers for asthma include allergens, viral respiratory infections, irritants, stimuli such as cold air or exercise and gastro-oesophageal reflux (Estes et al, 2013). Airway obstruction in asthmatics is variable and reversible. However poorly managed asthma can leave lasting structural changes in the cells and tissues of the lower respiratory tract, resulting in airway remodelling and permanent fibrotic damage (Kaufman, 2011). There is currently no cure for asthma, therefore the disease needs to be managed (NACA, 2014). Pathophysiology and assessment parameters It is important to understand the underlying pathophysiology of Mr Saunders’ presentation...

Chronic Obstructive Pulmonary Disease Case Study

...My case study is on a patient by the name of LaToya. LaToya is a fifty-one year-old black female. She was admitted to the medical-surgical department where I work, with a diagnosis of exacerbation of chronic obstructive pulmonary disease. She has a 66 pack-year history, meaning she smoked the equivalent of 365 packs of cigarettes for 66 years, and occasional drug and alcohol use. LaToya is divorced and lives alone in an older apartment building. Chronic obstructive pulmonary disease (COPD) is a lung disease that limits your airflow. COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. COPD is a progressive disease that makes it hard to breathe and the symptoms will get worse over time. Most cases of COPD occur as a result of long-term exposure to lung irritants that damage the lungs and the airways. Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. One of the greatest challenges for LaToya is to stop smoking. According to the Center for Disease Control (2012), the most important step a smoker can take after getting a COPD diagnosis is to quit. Not only will it make breathing easier, but it will cut down on the risk of severe...

Diabetic Ketoacidosis

...Nursing has always been a profession that embraces diversity towards rendering holistic patient care. However, with the constant changes in nursing practice; patient safety has been at risk due to nurse’s competence towards detecting impending patient deterioration that may lead to further complications or even death. It is said that the most important practical lesson that can be given to nurses, is to teach them what to observe (Nightingale 1969). Having the ability to observe and interpret critical situations are the essential key features applied in clinical practice. Effective observation of ward patients is the first step in identifying the deteriorating patient and effectively managing their care (Odell, Victor & Oliver 2009, p. 1993). Studies have shown that poor vital sign recording, lack of knowledge, failure to respond to abnormal signs, lack of knowledge, lack of supervision and failure to report deterioration or seek advice, have all contributed to the suboptimal care of ward patients (Odell, Victor & Oliver, cited in McGloin et al. 1999; McQuilla et al. 1998; Smith & Wood 1998; Hodgetts et al. 2002, p. 1993). With constant observation established, patient safety is implemented and surveillance is then incorporated to be able to identify and prevent possible medical errors and adverse events that may be encountered. The purpose of surveillance is the early identification of risk and the need for intervention and to alert nurses to both anticipated and unanticipated changes...

...Cardiovascular The cardiovascular system is consists of the heart and network of arteries, veins, and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries. The condition marked by the heart’s inability to pump enough blood to the rest of the body is called a heart failure, although it is generally long term or chronic, it may have a sudden onset. In the case study presented here the client complains: “I have shortness of breath, fatigue, cough, and swelling in feet”. Based on the above information during the initial interview the examiner will collect an additional subjective data in order to gain in depth understanding of what is the cause of the exhibited symptoms, and to rule out certain issues. Subjective data: 1) Dyspnea. (Shortness of breath) What kind of activities and amounts bring on shortness of breath. Did these activities bring the shortness of breath 6 months ago? Does shortness of breath come on suddenly? Is it constant or comes and goes? Is it changed by the position change, for example lying down? Does it wake you up at night? Does the shortness of breath interfere with ADLs? 2) Fatigue...

...The human brain is the most complex, most sophisticated body organ which makes us superior among other living creatures. It is the vessel of the greatest power ever invented. Since it is a treasure not any pleasure could ever equal it is encapsulated on a hard mass of bone to keep its treasure. The human brain can be divided into four major divisions: The cerebrum, the diencephalon, the cerebellum and the midbrain. The first division is further subdivided into four parts. The frontal lobe, the parietal lobe and the occipital lobe. In the frontal lobe, the precentral gyrus (motor cortex) controls voluntary motor activity. The Broca’s area coordinates the complex muscular activity of the mouth, tongue, and larynx and makes expressive motor speech possible. The frontal area also controls attention and concentration, motivation, ability to formulate goals, the ability to plan, the ability to initiate and maintain action, ability to self monitor and the ability to use feedback (executive functions). These areas contribute to reasoning, problem solving and emotional stability. The parietal lobes interpret temperature, touch and pleasure. Concept formation and abstraction happens and are formulated in this area. The parietal lobes form two sides; the left parietal lobe and the right parietal lobe. The left parietal lobe assists with right and left orientation and mathematics, while the right parietal lobe is used for awareness, as to shape (steriognosis) and size...

Introduction: The causes of Asthma: Looking at some recent reports of asthma disease, most of the acute exacerbation because cold and phlegm caused by dysfunction of the lungs which occurred in sputum of asthma. Chronic repeatedly patients mostly offset organs function. Its complex etiology occurs due to some reasons of genetic, physical fitness, diet, environment, age, and other factors related to work and rest, and emphasize internal and external consistency due to infestation. Asthma patients in the onset of the disease is often accompanied by an abnormal increase in serum IgE, IgE is the primary antibody of Ι type hypersensitivity, when its binding to the antigen, mast cells and basophils release of large amounts of biologically active substances, causing a series Asthma disease symptoms, but also by the synthesis of IgE Ts cell regulation (Huang Zhiying 2011). The physiological basis of Asthma: There are many different causes of bronchial obstruction, which is the synonymous of asthma, such as bronchospasm, abnormalities, new growths, swelling of the bronchial mucosa and so on. Some causes may result in mechanical obstruction by new growth, foreign bodies and congenital abnormalities. There are also some secondary obstructions such as mucous secretions, bronchial mucosa swelling and bronchospasm. The reaction of bronchi to irritation with a kind of inside defense mechanism by human body. To antagonize...
