Pneumonia believed to be due to bacteria is treated with antibiotics. [11] If the pneumonia is severe, the affected person is generally hospitalized. [20] Oxygen therapy may be used if oxygen levels are low. [11] Each year, pneumonia affects about 450 million people globally (7% of the population) and results in about 4 million deaths.
Diagnosis of pneumonia is made clinically, rather than on the basis of a particular test. [13] Evaluation begins with a physical examination by a health provider, which may reveal fever, an increased respiratory rate , low blood pressure (hypotension), a fast heart rate (tachycardia) and changes in the amount of oxygen in the blood.
Pneumonia may develop complications such as a lung abscess, a round cavity in the lung caused by the infection, or may spread to the pleural cavity. [ citation needed ] Poor oral care may be a contributing factor to lower respiratory disease, as bacteria from gum disease may travel through airways and into the lungs.
This term actually refers to a pathological condition of the lungs, frequently demonstrated by chest X-ray. Edema of the lungs should be thought of as the result of a disease such as congestive heart failure and not a disease in and of itself. In this case it would be a cardiac disease and not a pulmonary disease.
Multilobar pneumonia involves more than one lobe, and it often causes a more severe illness. Bronchial pneumonia affects the lungs in patches around the tubes (bronchi or bronchioles). Interstitial pneumonia involves the areas in between the alveoli, and it may be called "interstitial pneumonitis." It is more likely to be caused by viruses or ...
The bacterium can linger in the nose and throat without making a person sick, but people may develop pneumonia if it spreads to the lungs. Mycoplasma pneumonia is often a milder form of pneumonia ...
An irregular and often very fast heart rate. Premature ventricular contraction (PVC). ... Cardiovascular disease is a catchall term for any condition that affects the heart or blood vessels. It ...
Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1] [2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
