Pneumonia is an inflammation of the lung parenchyma that is caused by a microbial agent. “Pneumonitis” is a more general term that describes an inflammatory process in the lung tissue that may predispose a patient to or place a patient at risk for microbial invasion.
Sign and symptoms
Most people who develop pneumonia initially have symptoms of a cold (upper respiratory infection, for example, sneezing, sore throat, cough), which are then followed by a high fever (sometimes as high as 104 F), shaking chills, and a cough with sputum production. The sputum is usually discolored and sometimes bloody. Depending on the location of the infection, certain symptoms are more likely to develop. When the infection settles in the air passages, cough and sputum tend to predominate the symptoms. In some, the spongy tissue of the lungs that contain the air sacs is more involved. In this case, oxygenation can be impaired, along with stiffening of the lung, which results in shortness of breath. At times, the individual's skin color may change and become dusky or purplish (a condition known as "cyanosis") due to their blood being poorly oxygenated.
The only pain fibers in the lung are on the surface of the lung, in the area known as the pleura. Chest pain may develop if the outer aspects of the lung close to the pleura are involved. This pain is usually sharp and worsens when taking a deep breath and is known as pleuritic pain or pleurisy. In other cases of pneumonia, depending on the causative organism, there can be a slow onset of symptoms. A worsening cough, headaches, and muscle aches may be the only symptoms.
Children and babies who develop pneumonia often do not have any specific signs of a chest infection but develop a fever, appear quite ill, and can become lethargic. Elderly people may also have few symptoms with pneumonia.
Treatment for Pneumonia
The treatment of this inflammatory condition in varies according to the extent of infection. When detected early this can be treated from home and immunity needs no hospitalisation. Commonly used vaccines for pneumonia contain non-active bacteria or virus which enhances. The selection of an appropriate antibody is important. Home therapy involves few basic steps such as drinking lot of fluids and chest therapy.
