Pneumonia is a common disease, which occurs in all age groups. However, pneumonia is the leading cause of death in elderly, people who are chronically and terminally ill, and children under five years old worldwide. It can result from a variety of causes, including infection with bacteria, viruses, fungi, or parasites, and chemical or physical injury to the lungs. Pneumonia is an irregular inflammatory condition of the lung. It is often described as inflammation and abnormal fluid filling of the alveoli of the lung, which are microscopic air filled sacs in the lungs responsible for gas exchange. [2] Typical symptoms associated with pneumonia include cough, chest pain, fever, and difficulty in breathing. Diagnostic tools include x-rays and …show more content…
The most common causes of bacterial pneumonia are Streptococcus pneumoniae and "atypical" bacteria. Atypical bacteria are parasitic bacteria that live inside the cell or do not have a cell wall. Furthermore, they cause generally less severe pneumonia, therefore atypical symptoms, and respond to different antibiotics than other bacteria. In the nose or mouth of many healthy people, you can find Gram-positive type bacteria that cause pneumonia. In developing countries, approximately one million children annually are killed by Streptococcus pnuemoniae. Another important Gram-positive bacterium is Staphylococcus aureus, and Streptococcus agalactiae cause of pneumonia in newborn babies. Gram-negative bacteria cause pneumonia less often than gram-positive bacteria. Haemophilus influenzae, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Moraxella catarrhalis are some of the gram-negative bacteria that cause pneumonia. If vomit is inhaled, these bacteria may enter the lungs because it often lives in the stomach or intestines. Chlamydophila pneumoniae, Mycoplasma pneumoniae, and Legionella pneumophila are “atypical" bacteria, which cause pneumonia. [1] Fungal pneumonia is infrequent. However, individuals with immune system problems due to AIDS, immunosuppresive drugs, or other medical problems are vulnerable to fungal pneumonia. The pneumonia caused by fungi is similar to that of bacterial
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
Anyone can get pneumonia, but elderly, infants, and those with weakened immune system are at a higher risk. Pneumonia is commonly a complication of an upper respiratory system infection such as the influenza virus. Pneumonia often starts with symptoms that are typical of a common cold, like sore throat, nasal congestion and cough. As the infection develops in the lungs, symptoms such as fever, difficulty breathing, fatigue, wheezing, dry cough, shaking chills,
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)
Pneumonia is a serious infection of the lungs. This is when the air sacs in the lungs become inflamed and fill with pus and other liquid, which make it difficult for oxygen to reach the blood through them. If there is too little oxygen in the blood, then the body’s cells cannot work properly. Pneumonia can cause lack of oxygen and the spread of infection through the body, which may lead to death. An annual flu shot can provide protection against Pneumonia since it is similar to
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
Community acquired pneumonia (CAP) is and has been a major health problem here in the U.S. This disease mostly affects young children and the elderly 65. Streptococcus pneumoniae is the most common bacteria causing pneumonia, this bacterium has over 90 different stereotypes and is extremely hard to pin point the different mutating strains. Pneumonia is contracted from inhalation of droplets; any one coughing or sneezing around your area and carrying the virus can pass it along to you fairly easy. Pneumonia is an upper respiratory infection that causes the lungs to be inflamed and fill the alveoli (air sacs) with fluids causing lack of oxygen to the red blood cells. The most common test for S. pneumoniae is the optichin sensitivity with an optichin
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.
If pneumococcal pneumonia is being suspected, Gram-staining and culturing of blood sputum should be obtained. The presence of neutrophils and more than ten-gram-positive diplococcic means a diagnosis of S. pneumonia.
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).
We can define what pneumonia is and who it affects, but what happens to those with pneumonia? Depending on the type of pneumonia, symptoms vary. Bacterial pneumonia causes high fever, chills, rapid breathing, cough, chest pain when breathing and coughing, nausea, tiredness, and other symptoms. Those with atypical or mycoplasma pneumonia, symptoms include dry
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.
