What does pneumonia look like in the lung?

What does pneumonia look like in the lung?

Along with bacteria and fungi, they fill the air sacs within your lungs (alveoli). Breathing may be labored. A classic sign of bacterial pneumonia is a cough that produces thick, blood-tinged or yellowish-greenish sputum with pus. Pneumonia is an infection that inflames the air sacs in one or both lungs.

What does airspace consolidation mean?

Airspace consolidation is defined as replacement of gas within the airspaces by fluid, protein, cells, or other material.

What is the definition of airspace?

: the space lying above the earth or above a certain area of land or water especially : the space lying above a nation and coming under its jurisdiction.

Why is vocal Fremitus increased in consolidation?

The reason for increased fremitus in a consolidated lung is the fact that the sound waves are transmitted with less decay in a solid or fluid medium (the consolidation) than in a gaseous medium (aerated lung).

How do you get rid of lung consolidation?

How is a lung consolidation treated?

  1. Pneumonia. Pneumonia is treated with medication targeted to the organism that caused it.
  2. Pulmonary edema. Treatment of pulmonary edema is based on its cause.
  3. Pulmonary hemorrhage. If you have vasculitis, you’ll usually be treated with steroids and immunosuppressants.
  4. Aspiration.
  5. Cancer.

What causes consolidation?

Consolidation occurs through accumulation of inflammatory cellular exudate in the alveoli and adjoining ducts. The liquid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or hemorrhage from a pulmonary artery).

What causes atelectasis in the lungs?

Atelectasis is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the outside of the lung. Atelectasis is not the same as another type of collapsed lung called pneumothorax, which occurs when air escapes from the lung.

What do air Bronchograms indicate?

Air-bronchograms are gas-filled bronchi surrounded by alveoli filled with fluid, pus or other material 1. It is a very useful sign because it is highly sensitive and specific for the presence of lung consolidation rather than collapse.

How do you know if you have air Bronchogram?


  1. dynamic air bronchograms move centrifugally with respiration. represent fluid mixed with air inside larger bronchi, which are in continuity with the gas inspired by the patient.
  2. static air bronchograms lack detectable movement. indicate isolated, trapped air, consistent with resorptive atelectasis.

What diagnosis does the presence of air Bronchograms suggest?

The shape and lumen of the bronchi with air bronchogram sign can be used to distinguish lung cancer, tuberculosis, and pneumonia.

What is the silhouette sign?

In radiology, the silhouette sign refers to the loss of normal borders between thoracic structures. It is usually caused by an intrathoracic radiopaque mass that touches the border of the heart or aorta.

What is normal cardiac silhouette?

I did chest x-ray and the result said, “Cardiac silhouette appears prominent and the CTR is approximately 57 percent.” What does this mean? A normal measurement should be less than 0.5. A number > 0.5 may suggest enlargement of the heart chamber size.

What does it mean when the cardiac silhouette is enlarged?

An enlarged heart may be the result of a short-term stress on the body, such as pregnancy, or a medical condition, such as the weakening of the heart muscle, coronary artery disease, heart valve problems or abnormal heart rhythms.

What is meant by cardiac silhouette?

Cardiac silhouette refers to the outline of the heart as seen on frontal and lateral chest radiographs and forms part of the cardiomediastinal contour. The size and shape of the cardiac silhouette provide useful clues for underlying disease.

What is the symptoms of heart enlargement?

Symptoms of an enlarged heart

  • breathing problems.
  • shortness of breath.
  • dizziness.
  • irregular heartbeat (arrhythmia)
  • heart palpitations.
  • fluid retention.

How is cardiac silhouette measured?

Cardiac size is measured by drawing vertical parallel lines down the most lateral points of the heart and measuring between them. Thoracic width is measured by drawing vertical parallel lines down the inner aspect of the widest points of the rib cage, and measuring between them.

Can you live a normal life with enlarged heart?

It may not pump blood effectively, which can cause congestive heart failure. It may improve over time. But most people with an enlarged heart need lifelong treatment with medications.

Is it OK to exercise with an enlarged heart?

According to new research, aerobic exercise does just that for patients with stable heart failure, literally turning an enlarged heart into a trimmer, more efficient organ for pumping blood throughout the body.

What is the life expectancy of someone with diastolic heart failure?

Diastolic HF is associated with high mortality comparable with that of HF with depressed ejection fraction with a five year survival rate after a first episode of 43% and a higher excess mortality compared with the general population.
