What is pneumonia? Pneumonia is an infection in one or both lungs. Many small microbes such as bacteria, viruses and fungi can cause pneumonia. Pneumonia is not a disease. It can have more than 30 different reasons. Understanding the causes of pneumonia is important because pneumonia treatment depends on its cause. Approximately one third of cases of pneumonia in the United States each year are caused by respiratory viruses. These viruses are the most common cause of pneumonia in children younger than 5 years. The influenza virus is the most common cause of viral pneumonia in adults. Other viruses that cause pneumonia include respiratory syncytial virus rynovirusy, herpes simplex virus, severe acute respiratory syndrome (VHRS), and more. As pneumonia affects the body? Most of the time, the body filter bacteria from the air that we breathe. This makes the lungs from infection. But sometimes the germs find a way to get into the lungs and cause infection. It is more likely to happen if:
Your immune system is weak. Rostock is very strong. Your body can not filter out germs from the air you breathe. When germs that cause pneumonia reaches the lungs, lung air sacs (alveoli) become inflamed and filled with fluid and pus. It causes symptoms of pneumonia such as cough, fever, chills and shortness of breath. If you have pneumonia, oxygen has trouble reaching your blood. If there is too little oxygen in the blood cells of your body can not function properly. Because of this and spreading infection through the body pneumonia can cause death. Pneumonia affects the lungs in two ways. Partial pneumonia affects part (share) lungs. Bronchial pneumonia (or bronchopneumonia) affects patches throughout both lungs. What is pneumonia? Many small germs can cause pneumonia. There are five main causes of pneumonia:
Other infectious agents such as fungi - including pneumonia
If you have viral pneumonia, you are also at risk of getting bacterial pneumonia. What are the different types of pneumonia? Bacterial pneumonia can attack anyone at any age. Bacterial pneumonia can occur by itself or develop after it has been cold or flu. People who are most at risk of bacterial pneumonia include people, convalescents after surgery, people with respiratory diseases and viral infections and people who have weakened immune systems. If protecting your body is weakenedby illness, old age, malnutrition or violation immunitythe pneumonia bacteria that can live in a healthy throat can multiply and work their way into the lungs. This infection can quickly spread through the bloodstream and penetrate into the body. Dozens of different species of bacteria can cause pneumonia. The most common cause of bacterial pneumonia in adults pneumoniae (pneumococcus), but there is no vaccine for this form of pneumonia. Atypical pneumonia is often called walking pneumonia caused by bacteria, such as lehyonelly Pneumophila, mycoplasma pneumonia, and Chlamydophila pneumonia. Pnevmotsistnoy pneumonia sometimes occurs in people whose immune system is compromised (because of AIDS or certain medications that suppress the immune system). Other bacteria that can cause pneumonia include Staphylococcus aureus, Moraxella catarrhal, Streptococcus pyogenes, Neisseria meningitidis, Klebsiella pneumonia and Haemophilus influenzae. Most respiratory viruses attack the upper respiratory tract, but some causes of pneumonia, especially in children. Most of these pneumonias are not serious and last a short time, while others can be very serious. Viral pneumonia caused by influenza virus can be severe and sometimes fatal. The virus enters the lungs and multiplies, but almost no physical signs of lung tissue becomes filled with fluid. This pneumonia is the most serious in people with existing heart or lung disease and pregnant women. In extreme cases, the patient's acute need for air and extreme breathlessness.
Viral pneumonia may be complicated by bacterial invasion, with all the typical symptoms of bacterial pneumonia. Mycoplasmas are the smallest free living pathogens in humanity. They do not belong, they are bacteria or viruses, but they have features of both. Mycoplasmas cause a mild and widespread pneumonia. They affect all age groups but most often occur in older children and young people. Tuberculosis can cause inflammation of the lungs (pneumonia tuberculosis). This is a very serious pneumonia and very dangerous if treatment is started early. Pnevmotsistnoy pneumonia (SSR) is caused by an organism is the fungus. PCP can be the first sign of disease many people with AIDS. PCP can be successfully treated in many cases. This can be repeated several months later, but treatment can help prevent or delay relapse. Other less common pneumonias may be quite severe, and occur more frequently. Various special pneumonias are caused by inhalation of food, liquids, gases and dust, and fungi. Rickettsia (also considered an organism somewhere between viruses and bacteria) cause spotted fever Rocky Mountains, Ku fever, typhus and psittacosis, diseases that may have moderate or severe impact on the lungs. How serious is pneumonia? Pneumonia can be very serious and can lead to death. Pneumonia is usually more serious consequences for infants and young children, the elderly (people 65 and older), people who have other chronic health problems and people who have weak immune system as a result of illness or other factors . If you develop pneumonia, your chances lasix 40 mg iv of rapid recovery of most, if:
With treatment, most patients improved within two weeks. Elderly and debilitated patients may require more prolonged treatment. If you take antibiotics, your doctor can make sure your chest x-ray becomes normal again after you finish all requirements. It may take several weeks to clear X-ray. Possible complications People with other serious health problems such as diabetes or cirrhosis >> << respiratory failure requiring ventilator or breathing machine
sepsis, a condition in which there is uncontrolled swelling ( inflammation) in the body that can lead to organ failure
acute respiratory distress syndrome (HRDS), a severe form of respiratory failure
emphysema or abscessesThese rare but serious complication of pneumonia. They occur when pockets of pus form around or inside the lungs. They can sometimes must be removed surgically. Who gets pneumonia? Anyone can get pneumonia, but some people are prone to higher risk than others to get pneumonia. Latest SARS infectiona cold, laryngitis, etc.
Difficulty swallowing (due to stroke, dementia, Parkinson's disease and other neurological diseases)
Chronic lung disease, such as
or other serious diseases such as heart disease, cirrhosis, diabetes mellitus or
disorders of consciousness (loss of brain activity through dementia, stroke or other neurological diseases)
having a weakened immune system due to illness, certain medications, and autoimmune disease.
