The 4 stages of Pneumonia are Consolidation, Red Hepatization, Grey Hepatization, and Resolution.

  • Consolidation (Congestion)
    • The presence of exudate (a mass of cells and fluid) begins.
    • Occurs during the first 24 hours
    • Lasts about 1 day
  • Red Hepatization (Early Consolidation)
    • When red blood cells, white blood cells (neutrophils ), and fibrin (fibers in the blood that help with clotting) in the alveolus/ alveoli (the tiny air sacs of the lungs) enter the fluid-filled lungs.
    • Occurs 2 to 3 days after Consolidation
    • Lasts from 2 to 4 days
  • Grey Hepatization (Late Consolidation)
    • The red blood cells during the previous stage - red hepatization have begun to disintegrate, the fibrin mass and fluid continue to persist. In this stage, the lung tissue turns yellow to grayish-brown.
    • Occurs 2 to 3 days after Red Hepatization
    • Lasts from 4 to 8 days
  • Resolution (Restoration)
    • This stage means that the patient has completely recovered.
    • Occurs from day 6 to 13, with full recovery lasting more than 28 days.

  • Fever
  • Shortness of breath
  • Rapid, shallow breathing

What is Pneumonia?

  • Pneumonia is an infection of one or both of the lungs and can be viral or bacterial, with most people coming down with the latter.


How to treat Pneumonia?

  • Your first step should be to see a qualified physician so that they can give you an official diagnosis and prescribe any medications such as an antibiotic or an anti-viral.
  • After you have visited a primary care physician or walk-in clinic, you may experience a fever which can be controlled with aspirin, ibuprofen, or naproxen (Aleve, Wal-Proxen, Naprosyn)
  • Drinking fluids helps to bring up phlegm and loosen secretions.
  • Cough medicines should be avoided since coughing is your body's way of removing the infection.
  • Humidifiers, steam baths, and warm drinks help to ease your breathing and open up your airways, hot tea with honey is a favorite around our house.
  • Do not smoke, stay away from wood fires, etc.
  • Rest, rest, rest, and more rest.
  • If your symptoms persist or worsen notify your physician to get their recommendations.
