Pneumonia Flashcards

Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing symptoms such as cough, fever, chills, and difficulty breathing.

Common symptoms include cough, fever, shortness of breath, chest pain, fatigue, muscle pain, headache, confusion, nausea, vomiting, and loss of appetite.

Pneumonia can be caused by a variety of organisms, including bacteria, viruses, and fungi.

Infants, young children, people older than age 65, and those with underlying health problems or weakened immune systems are at higher risk.

Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place, crucial for effective respiration.

Pulmonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred, making it difficult for the lungs to function properly.

Edwin Klebs was a prominent German-Swiss pathologist known for his work in bacteriology and for discovering the bacterium Corynebacterium diphtheriae.

Streptococcus pneumoniae is a Gram-positive bacterium commonly associated with community-acquired pneumonia, while Klebsiella pneumoniae is a Gram-negative bacterium often linked to hospital-acquired infections and known for its antibiotic resistance.

Penicillin, discovered by Alexander Fleming, was the first true antibiotic and revolutionized the treatment of bacterial infections.

Treatments for bacterial pneumonia typically include antibiotics, with the choice depending on the specific bacteria and local resistance patterns.

Supportive care includes oxygen therapy, intravenous fluids, pain and fever management, and rest to aid recovery.

Vaccines such as the pneumococcal vaccine and the influenza vaccine are available to help prevent pneumonia, especially in high-risk groups.

Pneumonia was once referred to as 'the old man's friend' because it often resulted in a relatively peaceful death for elderly patients suffering from other painful conditions.

Good hygiene, not smoking, and maintaining a healthy lifestyle can help prevent pneumonia.

Common laboratory findings may include lymphopenia, prolonged prothrombin time, and elevated lactate dehydrogenase.

Antiviral medications may be prescribed for viral pneumonia, such as oseltamivir for influenza.

Oxygen therapy is crucial for maintaining adequate oxygen levels in the blood, especially in severe cases of pneumonia.

Symptoms of pulmonary fibrosis often include persistent dry cough, fatigue, unexplained weight loss, and aching muscles and joints.

The 2019 novel coronavirus (2019-nCoV) was linked to pneumonia cases in Wuhan, China, highlighting the need for enhanced surveillance and research.

Hospitalization may be required for severe pneumonia cases to provide intensive treatments, including intravenous antibiotics and advanced respiratory support.

Antibiotic resistance, particularly in bacteria like Klebsiella pneumoniae, makes infections difficult to treat and poses a significant challenge in managing pneumonia.

Common complications of pneumonia include acute respiratory distress syndrome, arrhythmia, and shock.

Pneumonia can affect individuals of all ages, but it is particularly serious for infants, young children, and the elderly.
