A pulmonary hematoma is a collection of blood within the tissue of the lung. It may result when a pulmonary laceration fills with blood. [ 1 ] A lung laceration filled with air is called a pneumatocele . [ 1 ]
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.
Therefore, mild pneumonia might be better dealt with inside the long-term care facility. [28] [29] [30] In patients with a limited life expectancy (for example, those with advanced dementia), end-of-life pneumonia also requires recognition and appropriate, palliative care. [31]
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
People may become infected with pneumonia in a hospital; this is defined as pneumonia not present at the time of admission (symptoms must start at least 48 hours after admission). [ 85 ] [ 84 ] It is likely to involve hospital-acquired infections , with higher risk of multidrug-resistant pathogens.
Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. [1] The scarring ( pulmonary fibrosis ) involves the pulmonary interstitium (the supporting framework of the lung).
Lower respiratory tract infection (LRTI) is a term often used as a synonym for pneumonia but can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath , weakness, fever , coughing and fatigue. [ 3 ]
The pneumonia progresses for two to four days and may cause respiratory failure and shock. Patients will die without early treatment, some within 36 hours.
