On November 12, Barnabas Health recognizes World Pneumonia Day.
New Jersey -- Each year in the United States, about 1 million people are hospitalized
with pneumonia, and approximately 50,000 people die from the disease,
reports the Centers for Disease Control and Prevention.
According to the Barnabas Health Advanced Lung Disease and Transplant Program
at Newark Beth Israel Medical Center in Newark, New Jersey’s only
lung transplant program, 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 in the lungs fill with pus and other liquid. It
can affect one or more sections (lobes) of the lung (lobar pneumonia)
or patches throughout both lungs (bronchial pneumonia).
What are the different types of pneumonia?
The main types of pneumonia are:
- Bacterial pneumonia. This type is caused by various bacteria, the most
common of which is streptococcus pneumoniae. It usually occurs when the
body is weakened in some way, such as by illness, malnutrition, old age,
or impaired immunity and the bacteria are able to work their way into
the lungs. Bacterial pneumonia can affect all ages, but those at greater
risk include people who smoke, abuse alcohol, have respiratory diseases
or viral infections, have weakened immune symptoms, or have recently had surgery.
Symptoms of bacterial pneumonia include shaking and chills, low energy,
fatigue, loss of appetite, sharp or stabbing chest pain that worsens with
deep breathing or cough, high temperature, rapid pulse, rapid breathing,
bluish color to lips and nail beds, and/or a cough that produces greenish,
yellow, or bloody mucus.
- Viral pneumonia. This is caused by various viruses, including influenza,
and is responsible for one-third of all pneumonia cases. Early symptoms
of viral pneumonia are the same as those of bacterial pneumonia, which
may be followed by increasing breathlessness, headache, muscle pain, weakness,
and a worsening of the cough. Viral pneumonias may make a person susceptible
to bacterial pneumonia.
- Mycoplasma pneumonia. This type has somewhat different symptoms and physical
signs and is referred to as atypical pneumonia. It is caused by the mycoplasma
pneumoniae, the smallest known disease-causing agents, and which have
characteristics of both bacteria and viruses. They generally cause a mild,
widespread pneumonia that affects all age groups. Symptoms include a severe
cough that may produce some mucus.
How is pneumonia diagnosed?
Diagnosis is usually made based on the season and the extent of the illness.
Based on these factors, your health care provider may make a diagnosis
simply on a thorough history and physical examination, but may include
the following tests to confirm the diagnosis:
- Chest X-ray.
- Blood tests to analyze whether infection is present and if infection has
spread to the bloodstream (blood cultures). Arterial blood gas testing
determines if enough oxygen is in your bloodstream.
- Sputum culture. A diagnostic test performed on the material that is coughed
up from the lungs and into the mouth. A sputum culture is often performed
to determine if an infection is present.
- Pulse oximetry. An oximeter is a small machine that measures the amount
of oxygen in the blood. To obtain this measurement, a small sensor (like
a bandage) is taped onto a finger. When the machine is on, a small red
light can be seen in the sensor. The sensor is painless and the red light
does not get hot.
- Chest CT scan. A test that takes images of the structures in the chest
to see how the lungs are functioning.
- Bronchoscopy. A procedure used to look inside the airways of the lungs.
- Pleural fluid culture. A culture of a fluid sample taken from the pleural
space (space between the lungs and chest wall) to identify the bacteria
that cause pneumonia.
What is the treatment for pneumonia?
According to the Barnabas Health, specific treatment will be determined
by your health care provider based on your age, overall health, and medical
history; extent of the disease; your tolerance for specific medications,
procedures, or therapies; and expectations for the course of the disease.
It may include ay include antibiotics for bacterial pneumonia. Antibiotics
may also speed recovery from mycoplasma pneumonia and some special cases.
There is no clearly effective treatment for viral pneumonia, which usually
heals on its own. Other treatment may include appropriate diet, increased
fluids, oxygen therapy, pain medication, and medication for cough.
Preventing pneumonia involves taking care of your overall health and wellness.
Wash your hands frequently, especially during cold and flu season, don’t
smoke, get plenty of rest, eat well and get a flu shot annually.
