Pathogenesis, Clinical Picture, Diagnosis, And Treatment Of Pneumococcal Lobar Pneumonia

Pneumonia is an acute infection of the lungs, it can be caused by a variety of organisms entering the body – including bacteria, viruses or fungi. The infection causes an inflammation of the alveoli (air sacs) of the lungs and may result in the alveoli filling with fluid or other purulent material (Mayo Clinic, 2016). An accumulation of fluid within alveoli and portions of the lungs, can reduce the ability of the lungs to allow for oxygen diffusion across the alveoli walls. If oxygen saturation is low, it can cause the body’s cells to not work effectively. Therefore, the risk of the infection spreading through the body is increased – it is due to this reason, that pneumonia can be life-threatening (American Lung Foundation, 2016). Pneumonia

* Pneumonia is refers to an infection in the lungs that causes swelling in the lungs tissue and this inflammation

This paper explores Pneumonia and the respiratory disease process associated with bacterial and viral pathogens most commonly located in the lung. The paper examines the process, symptoms and treatments most commonly viewed in patient cases of Pneumonia. My goal is to educate the reader and to warn of the

Pneumonia is a disease that affects the respiratory system. Specifically, it is an inflammation of the lungs that can be caused by fungi, bacteria, viruses and parasites. Microscopic sacs in the lungs (Alveoli) become inflamed and fill up with fluid, which causes symptoms such as cough, fever, chills and trouble breathing. It is a lung disease that kills thousands every year and hospitalizes many more. Pneumonia is more serious and can be deadly for infants and elderly. This disease has personally affected me when my son was hospitalized with it for 5 days. He was only 10 months old at the time and was admitted with diagnosis of Pneumonia, low oxygen and dehydration.

Pneumonia is described in Tabers cyclopedia medical dictionary, “as inflammation of the lungs, usually due to an infection with bacteria, viruses, or other pathogenic organisms” (p.1833)

According to the University of Virginia (n.d.) in the radiographic findings seen in patients with pneumonia are airspace opacity, lobar consolidation, or interstitial opacities; pneumonia is a space occupying lesion without volume loss (University of University, n.d.).

One way is it caused your body to have inflammation. That happens because it breaks down the tissue between the air sacs and that is a major malt function. When  the tissue breaks down then liquid goes out to the respiratory system and causes fatigue, chills, chest pain, coughing thoracic pain, and vomiting. It also causes “a breakdown in your body's natural defenses which allows germs to invaded multiply in your lungs.” (RM healthy)  when does natural defenses break down back and we did chest pain in chest infections. Those are the malfunctions your body has with

The client’s secondary diagnosis is community-acquired pneumonia. Typically, immune defense mechanisms, such as the secretion of alveolar macrophages and immunoglobulins A and G, protect the lower airway from infection. Streptococcus pneumoniae, the most common causative agent of community-acquired pneumonia, invades the lungs. The organism triggers an inflammatory response, resulting in increased blood flow and vascular permeability. Neutrophil activation occurs, to surround the kill the invading organism. A combination of the offending organism, neutrophils and fluid from the surrounding blood vessels flood the alveoli, inhibiting normal oxygen transportation. This filling of the alveoli may lead to tachypnea, tachycardia and dyspnea. Further obstruction of airflow and an increased impairment of gas exchange occur as mucous production increases. When

Pneumonia is an inflammation of the lung which results into an excess of fluid or pus accumulating into the alveoli of the lung. Pneumonia impairs gas exchange which leads to hypoxemia and is acquire by inhaling a contagious organism or an irritating agent. (Ignatavicius & Workman, 2013). Fungal, bacteria and viruses are the most common organisms that can be inhale. Pneumonia could be community-acquired or health care associated. Community –acquired pneumonia (CAP) occurs out of a healthcare facility while health care associated pneumonia (HAP) is acquired in a healthcare facility. HAP are more resistant to antibiotic and patients on ventilators and those receiving kidney dialysis have a higher risk factor. Infants, children and the elderly also have a higher risk of acquiring pneumonia due to their immune system inability to fight the virus. Pneumonia can also be classified as aspiration pneumonia if it arises by inhaling saliva, vomit, food or drink into the lungs. Patients with abnormal gag reflex, dysphagia, brain injury, and are abusing drug or alcohol have a higher risk of aspiration pneumonia (Mayo Clinic, 2013). In the case of patient E.O., this patient had rhonchi in the lower lobe and the upper lobe sound was coarse and diminished. Signs and symptoms of pneumonia include difficulty breathing, chest pain, wheezing, fever, headache, chills, cough, confusion, pain in muscle or

Streptococcus pneumoniae is found worldwide. The common host is the human body, in which it often does not cause disease but at other times it can cause diseses in particular, pneumonia. It also causes otitis media, bacteremia, meningitis, peritonitis, and sinusitis. The route by which this organism is spread is from human to human in the form of aerosol droplets. When inside the host the organism’s primary site of pneumococcal colonization is the nasopharynx. From this site it can aspire to the lungs, eventually spread to the blood and traverse the blood-brain barrier to the meninges, once inside the blood it can cause infections throughout the body. Symptoms of the disease include sudden

Pneumonia is an illness of the lower respiratory tract in which the lungs become inflamed and congested and alveolar spaces are filled with fluid and cells-polymorphs and lymphocytes (Mandell L.A). It is an inflammatory condition of the lung and it is one of the most serious infections, causing two million deaths annually among the young and elderly. Pneumonia is the largest killer, accounting for 28% to 34% of all child deaths below five years of age in low-income countries and is an important cause of mortality in the elderly in high-income countries (Suárez).

Mrs. A (pseudonym) is an 83-year-old Samoan female of Christian religion who was admitted to an urban hospital on 02/04/15 by GP referral. She came in with chest pain associated with productive cough and shortness of breath (SOB) on exertion. She also complained of having recurrent episodes of vomiting mixed with saliva and fatigue. She has a history of asthma, hypertension, type 2 diabetes mellitus on Metformin and double incontinence due to a long-standing history of intermittent constipation. Her chest computed tomographic (CT) revealed right lower lobe opacity indicating pulmonary consolidation, which means that her right lower lung has accumulated exudates in the alveoli that would have normally been filled by gas, indicative of bacterial pneumonia. Furthermore, a sputum gram stain sample collected from Mrs. A showed gram-positive bacteria, which is also a characteristic of pneumonia. Her blood tests revealed a high haemoglobin count, which may be caused by an underlying lung disease, as well as high white blood cell count confirming the presence of infection. Considering all diagnostic results, Mrs. A was diagnosed with right lower lobe bacterial pneumonia.

Mycoplasma Pneumonia is the most common pneumonia ranging in older kids and younger adults. This type of lung infection goes by many different names such as Walking Pneumonia, Eaton Agent Pneumonia and Primary Atypical Pneumonia. Mycoplasma Pneumoniae is one of the smallest living organisms that can reproduce outside of a cell but, prefers to have a host and to be parasitic. Mycoplasma pneumoniae likes to party in the late summer and early fall especially in communities but is still found in the other seasons.

The clinical manifestations of pneumonia will be different according to the causative organism and the patient’s underlying conditions and/or comorbidities (Smeltzer, et al). Some of the manifestations are

Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus. Pneumonia can also be caused by inhaling vomit or other foreign substances. In all cases, the lungs' air sacs fill with pus , mucous, and other liquids and cannot function properly. This means oxygen cannot reach the blood and the cells of the body.
