Research Paper On 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 an infection of the lungs. Many different organisms can cause it, including bacteria, viruses, and fungi. Pneumonia can range from mild to severe, and can even be deadly. The severity depends on the type of organism causing pneumonia, as well as your age and underlying health.

When CAP occurs, it is determined if the need for hospitalisation is necessary as it depends on the seriousness of the infection. Gram- positive organisms such as S. pneumoniae, naturally occur in the upper respiratory tract, is one cause of lower respiratory infections such as pneumonia, but is also a culprit in causing upper respiratory infections like otitis media. H. influenzae is just one of many bacterial infections that can result in CAP, it therefore can be subacute and present with a low-grade fever and a persistent cough for a few weeks before a patient has a diagnosis. Adults that have very little or no immunity are an easier target for certain viruses such as that of the Cytomegalovirus, which is a viral pathogen that is commonly contracted within the community, other common virus are adenovirus and herpes simplex. When a virus starts to become acute, it starts an infection within the ciliated cells within the airway. When pneumonia occurs from this viral infection, the inflammatory action starts to seep into the alveolar areas and leads to the problem of excess exudation and oedema within the respiratory tract. It is sometimes often difficult to differentiate symptoms of a viral pneumonia from that of bacterial pneumonia (Smeltzer &

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

pneumoniae and there chemotactic signals and the host cell’s alternate pathway, invade the alveoli. Also red blood cells are recruited to this site. In the third stage, mostly neutrophils are packed into the alveoli and very few bacteria remain. In the final stage, macrophages eliminate the remaining residue from the inflammatory response. As one can see, the damage which is done to the lung is largely a result of the host’s inflammatory response, which causes the build up of fluids in the lungs. If S. pneumoniae is allowed to persist in the lungs it can then invade the blood, which causes bacteremia. When in the blood it can traverse the blood-brain barrier and infect the meninges, which results in meningitis. S. pneumoniae is also associated with diseases in other parts of the respiratory tract including the paranasal sinuses, which is better known as sinusitis, and the middle ear can become infected, which is known as otitis media. It has also been known to cause peritonitis, an inflammation of the peritoneum, the membrane that lines the abdominal wall, and it is also implicated in causing arthritis.

Pneumonias most common form is the Streptococcus pneumoniae but when it is caused by another bacterium it is called atypical pneumonia or walking pneumonia which usually causes a less severe form of the disease (hajiliadas, 2014). However pneumonia caused by the typical bacterium Streptococcus pneumoniae can be very severe and even life threatening. Symptoms of pneumonia can range in type and severity of the disease but usually someone who has or is developing the illness will feel fatigued, be running a fever, and will develop a cough that will most likely produce phlegm. In some cases patients have developed fluid being released into the plural cavity and in mire severe cases that fluid can become infected. The diagnosis for this illness is very straight forward and usually can be diagnosed by taking a pulse oximetry test and/or a sputum test. However, if the illness is in advanced stages and life threating X-rays of the chest can be performed in order to determine the severity and progression of the illness. This disease is easily treatable by antibiotics but for more severe cases antibiotics usually do not help.

There are four different classifications of pneumonia including community-acquired pneumonia, hospital-acquired pneumonia, healthcare associated pneumonia, and ventilator-associated event which were previously referred to as ventilator-associated pneumonia (HESS). Bacteria, fungus, and viruses are some of the major causes of any type of pneumonia. Specifically, pneumococcus and Haemophilus, influenza are common pneumonia-causing bacteria. In children, these bacteria are the most present. Streptococcus pneumonia These microorganisms are capable of causing pneumonia, which is defined as inflamed air sacs in the lungs capable of developing fluid.

This condition is most often caused by the same virus that causes a cold. You can get this virus by coming into close contact with someone who is infected with this virus or by touching something that they coughed or sneezed on.

The symptoms that cause bronchitis include: coughing, phlegm, and fatigue with fever chest discomfort .A small amounts of white mucus are often coughed up. This mucus often changes from white to green or yellow. The color change does not mean there is a bacterial infection.

Aspiration pneumonia results from an abnormal entry of fluid or particulate secretions into the lower airways. Factors that may cause aspiration pneumonia are those that compromise our body’s defense mechanism to protect the lower airways. These mechanisms include: epiglottis, cough reflex, and the ability to clear our airways. When our swallowing mechanism become weak with age and or inactivity, especially something like stroke, it puts the body at risk for aspirating bacteria that is typically found in the oral and nasaopharynx. The organisms responsible for pneumonia include: “Streptococcus pneumonia, Haemophilus influenza, Staphylococcus aureus, and gram-negative bacteria” (Swaminathan, 2017). In addition, the occurrence of aspiration pneumonia

The major causes of bacterial bronchitis are Mycoplasma and Streptococcus pneumoniae (Pneumococcus) with protracted bacteria bronchitis usually caused by the

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.
