Pneumonia as seen on chest x-ray. A: Normal chest x-ray.B: Abnormal chest x-ray with shadowing from pneumonia in the right lung (left side of image).. Hospital-acquired pneumonia (HAP) or nosocomial pneumonia refers to any pneumonia contracted by a patient in a hospital at least 48–72 hours after being admitted.
Pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae. [1]S. pneumoniae is a common member of the bacterial flora colonizing the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. [2]
For adults and children in the hospital who require a respirator, there is no strong evidence indicating a difference between heat and moisture exchangers and heated humidifiers for preventing pneumonia. [109] There is tentative evidence that laying flat on the back compared to semi-raised increases pneumonia risks in people who are intubated ...
It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases.
The advantage of this classification scheme over previous systems is that it can help guide the selection of appropriate initial treatments even before the microbiologic cause of the pneumonia is known. There are two broad categories of pneumonia in this scheme: community-acquired pneumonia and hospital-acquired pneumonia.
Viral pneumonia is a pneumonia caused by a virus.Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [1]
Pneumonitis describes general inflammation of lung tissue. [1] [2] Possible causative agents include radiation therapy of the chest, [3] exposure to medications used during chemo-therapy, the inhalation of debris (e.g., animal dander), aspiration, herbicides or fluorocarbons and some systemic diseases.
Community-acquired pneumonia (CAP) refers to pneumonia (any of several lung diseases) contracted by a person outside of the healthcare system. In contrast, hospital-acquired pneumonia (HAP) is seen in patients who have recently visited a hospital or who live in long-term care facilities.
