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. [2]
Pneumonia fills the lung's alveoli with fluid, hindering oxygenation. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [56]
Most people who take a drug test take a presumptive test, cheaper and faster than other methods of testing. However, it is less accurate and can render false results. The FDA recommends for confirmatory testing to be conducted and the placing of a warning label on the presumptive drug test: "This assay provides only a preliminary result.
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 ( tachypnea ), low blood pressure ( hypotension ), a fast heart rate ( tachycardia ) and changes in the amount of oxygen in the ...
A dull, muffled sound may replace resonance in conditions like pneumonia or hemothorax. Hyper-resonance: Very loud, very low pitch, and longer in duration. Abnormal. [14] Hyper-resonance can result from asthma or emphysema; Tympany: Loud and high pitched. Common for percussion over gas-filled spaces. [14] Tympany may result in pneumothorax. [15]
Doctors have long urged people ages 50 and older to get a shot to protect against bacterial pneumonia.
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
Almost half of all U.S. adults have elevated blood pressure (systolic pressure between 120 and 19 and diastolic pressure less than 80). High blood pressure (hypertension, ...
