What is Lobar pneumonia?

Lobar pneumonia is an infection of one or more lobes of the lungs, usually caused by bacteria. It is characterized by inflammation of the lung tissue and typically presents with a sudden onset of fever, chills, cough, shortness of breath, and pleuritic chest pain. Pneumonia can be classified as either community-acquired or healthcare-acquired, depending on the location and circumstances in which it is contracted.

Signs and symptoms

• Sudden onset of fever and chills

• Coughing, initially dry and later with green sputum

• Chest pain that worsens when you breathe or cough

• Shortness of breath

• Rapid breathing

• Fatigue

• Loss of appetite

• Sweating

• Nausea or vomiting

• Confusion (in older adults)

Treatment

The treatment of pneumonia typically involves antibiotics to kill the causative bacteria and supportive measures to relieve symptoms. Antibiotics are chosen based on the likely causative organism and the patient's individual circumstances.

Supportive measures may include:

• Rest

• Adequate hydration

• Oxygen therapy if necessary

• Medications to relieve pain, fever, and cough

Prevention

Preventive measures for lobar pneumonia include:

• Vaccination against Streptococcus pneumoniae, Haemophilus influenzae, and influenza virus
