What is pneumonia?
Pneumonia is an infection of one or both of the lungs caused by bacteria, viruses, or fungi. It is a serious infection in which the air sacs fill with pus and other liquid.
- Lobar pneumonia affects one or more sections (lobes) of the lungs.
- Bronchial pneumonia (also known as bronchopneumonia) affects patches throughout both lungs.
What causes pneumonia?
There are more than 30 different causes of pneumonia, and they’re grouped by the cause. The main types of pneumonia are:
- source link Bacterial pneumonia. This type is caused by various bacteria. The most common is Streptococcus pneumoniae. It usually occurs when the body is weakened in some way, such as by illness, poor nutrition, old age, or impaired immunity, and the bacteria are able to work their way into the lungs. Bacterial pneumonia can affect all ages, but you are at greater risk if you abuse alcohol, smoke cigarettes, are debilitated, have recently had surgery, have a respiratory disease or viral infection, or have a weakened immune system.
- order best price free viagra Viral pneumonia. This type is caused by various viruses, including the flu (influenza), and is responsible for about one-third of all pneumonia cases. You may be more likely to get bacterial pneumonia if you have viral pneumonia.
- levitra user forum Mycoplasma pneumonia. This type has somewhat different symptoms and physical signs and is referred to as atypical pneumonia. It is caused by the bacterium Mycoplasma pneumoniae. It generally causes a mild, widespread pneumonia that affects all age groups.
- go here Other pneumonias. There are other less common pneumonias that may be caused by other infections including fungi.
Who is at risk for pneumonia?
Anyone can get pneumonia. However, the following groups are at the highest risk:
- Adults ages 65 and older
- Children younger than age 2
- People with certain medical conditions
- People that smoke
What are the symptoms of pneumonia?
The symptoms of bacterial pneumonia include:
- Bluish color to lips and fingernails
- Confused mental state or delirium, especially in older people
- Cough that produces green, yellow, or bloody mucus
- Heavy sweating
- Loss of appetite
- Low energy and extreme tiredness
- Rapid breathing
- Rapid pulse
- Shaking chills
- Sharp or stabbing chest pain that’s worse with deep breathing or coughing
- Shortness of breath that gets worse with activity
Early symptoms of viral pneumonia are the same as those of bacterial pneumonia, which may be followed by:
- Increasing shortness of breath
- Muscle pain
- Worsening of the cough
- Mycoplasma pneumonia has somewhat different symptoms, which include a severe cough that may produce mucus.
How is pneumonia diagnosed?
Diagnosis is usually made based on your recent health history (such as surgery, a cold, or travel exposures) and the extent of the illness. Based on these factors, your healthcare provider may diagnose pneumonia simply on a thorough history and physical exam. The following tests may be used to confirm the diagnosis:
- go site Chest X-ray. This test takes pictures of internal tissues, bones, and organs, including the lungs.
Blood tests. This test may be used to see whether infection is present and if infection has spread to the bloodstream (blood cultures). Arterial blood gas testing checks the amount of oxygen in your bloodstream.
- source link Sputum culture. This test is done on the material that is coughed up from the lungs and into the mouth. It’s often used to see if there’s an infection in the lungs.
- watch Pulse oximetry. An oximeter is a small machine that measures the amount of oxygen in the blood. A small sensor is taped or clipped onto a finger. When the machine is on, a small red light can be seen in the sensor. The test is painless and the red light does not get hot.
- go site Chest CT scan. This imaging procedure uses a combination of X-rays and computer technology to produce sharp, detailed horizontal, or axial, images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than regular X-rays.
Bronchoscopy. This is direct exam of the bronchi (the main airways of the lungs) using a flexible tube (called a bronchoscope). It helps to evaluate and diagnose lung problems, assess blockages, and take out samples of tissue and/or fluid for testing,
- see Pleural fluid culture. In this test, a sample of a fluid sample is taken from the pleural space. This is the space between the lungs and chest wall. A long, thin needle is put through the skin between the ribs and into the pleural space. Fluid is pulled into a syringe attached to the needle. It is sent to the lab where it’s tested to find out which bacteria is causing the pneumonia.
How is pneumonia treated?
Treatment depends on the type of pneumonia you have. Most of the time, pneumonia is treated at home, but severe cases may be treated in the hospital. Antibiotics are used for bacterial pneumonia. Antibiotics may also speed recovery from mycoplasma pneumonia and some special cases. Most viral pneumonias don’t have specific treatment. They usually get better on their own.
Other treatment may include eating well, increasing fluid intake, getting rest, oxygen therapy, pain medicine, fever control, and maybe cough-relief medicine if cough is severe.
Can pneumonia be prevented?
Check with your healthcare provider about getting immunizations. The flu is a common cause of pneumonia. Because of that, getting a flu shot every year can help prevent both the flu and pneumonia.
There is also a pneumococcal vaccine. It will protect you from a common form of bacterial pneumonia. Children younger than age 5 and adults ages 65 and older should get this shot.
The pneumococcal shot is also recommended for all children and adults who are at increased risk of pneumococcal disease due to other health conditions.
What are the complications of pneumonia?
Most people with pneumonia respond well to treatment, but pneumonia can be very serious and even deadly.
You are more likely to have complications if you are an older adult, a very young child, have a weakened immune system, or have a serious medical problem like diabetes or cirrhosis. Complications may include:
- http://maientertainmentlaw.com/?search=buy-prednisone-without-a-doctor-prescription-discount Acute respiratory distress syndrome (ARDS). This is a severe form of respiratory failure.
- Lung abscesses. These are pockets of pus that form inside or around the lung. They may need to be drained with surgery
- Respiratory failure. This requires the use of a breathing machine or ventilator.
- Sepsis. This is when the infection gets into the blood. It may lead to organ failure.
Key points about pneumonia
- Pneumonia is an infection of one or both of the lungs caused by bacteria, viruses, or fungi.
- There are more than 30 different causes of pneumonia, and they’re grouped by the cause. The main types of pneumonia are bacterial, viral, and mycoplasma pneumonia.

- Pneumonia can often be diagnosed with a thorough history and physical exam. Tests used to look at the lungs, blood tests, and tests done on the sputum you cough up may also be used.
- Treatment depends on the type of pneumonia you have. Antibiotics are used for bacterial pneumonia. It may also speed recovery from mycoplasma pneumonia and some special cases. Most viral pneumonias don’t have a specific treatment and just get better on their own.
